Cell

Specifies (some of) the contents of a single row/column/timestamp of a table.

Field name Type Description
timestamp_micros int64 The cell's stored timestamp, which also uniquely identifies it within its column. Values are always expressed in microseconds, but individual tables may set a coarser granularity to further restrict the allowed values. For example, a table which specifies millisecond granularity will only allow values of timestamp_micros which are multiples of 1000.
value bytes The value stored in the cell. May contain any byte string, including the empty string, up to 100MiB in length.
labels[] string Labels applied to the cell by a RowFilter.

CheckAndMutateRowRequest

Field name Type Description
table_name string The unique name of the table to which the conditional mutation should be applied. Values are of the form projects/<project>/instances/<instance>/tables/<table>
row_key bytes The key of the row to which the conditional mutation should be applied.
predicate_filter RowFilter The filter to be applied to the contents of the specified row. Depending on whether or not any results are yielded, either true_mutations or false_mutations will be executed. If unset, checks that the row contains any values at all.
true_mutations[] Mutation Changes to be atomically applied to the specified row if predicate_filter yields at least one cell when applied to row_key. Entries are applied in order, meaning that earlier mutations can be masked by later ones. Must contain at least one entry if false_mutations is empty, and at most 100000.
false_mutations[] Mutation Changes to be atomically applied to the specified row if predicate_filter does not yield any cells when applied to row_key. Entries are applied in order, meaning that earlier mutations can be masked by later ones. Must contain at least one entry if true_mutations is empty, and at most 100000.

CheckAndMutateRowResponse

Response message for Bigtable.CheckAndMutateRow.

cells[] Cell Must not be empty. Sorted in order of decreasing "timestamp_micros".

ColumnRange

Specifies a contiguous range of columns within a single column family. The range spans from <column_family>:<start_qualifier> to <column_family>:<end_qualifier>, where both bounds can be either inclusive or exclusive.

Union field end_qualifier. The column qualifier at which to end the range (within column_family). If neither field is set, interpreted as the infinite string, exclusive. end_qualifier can be only one of the following:
end_qualifier_closed bytes Used when giving an inclusive upper bound for the range.
end_qualifier_open bytes Used when giving an exclusive upper bound for the range.

Family

Specifies (some of) the contents of a single row/column family intersection of a table.

Field name Type Description
name string The unique key which identifies this family within its row. This is the same key that's used to identify the family in, for example, a RowFilter which sets its "family_name_regex_filter" field. Must match [-_.a-zA-Z0-9]+, except that AggregatingRowProcessors may produce cells in a sentinel family with an empty name. Must be no greater than 64 characters in length.

column_qualifier bytes The qualifier of the column into which new data should be written. Can be any byte string, including the empty string.
timestamp_micros int64 The timestamp of the cell into which new data should be written. Use -1 for current Bigtable server time. Otherwise, the client should set this value itself, noting that the default value is a timestamp of zero if the field is left unspecified. Values must match the granularity of the table (e.g. micros, millis).
value bytes The value to be written into the specified cell.

ReadModifyWriteRowRequest

Request message for Bigtable.ReadModifyWriteRow.

Field name Type Description
table_name string The unique name of the table to which the read/modify/write rules should be applied. Values are of the form projects/<project>/instances/<instance>/tables/<table>
row_key bytes The key of the row to which the read/modify/write rules should be applied.
rules[] ReadModifyWriteRule Rules specifying how the specified row's contents are to be transformed into writes. Entries are applied in order, meaning that earlier rules will affect the results of later ones.

ReadModifyWriteRowResponse

Response message for Bigtable.ReadModifyWriteRow.

Field name Type Description
row Row A Row containing the new contents of all cells modified by the request.

ReadModifyWriteRule

Specifies an atomic read/modify/write operation on the latest value of the specified column.

Field name Type Description

column_qualifier bytes The qualifier of the column to which the read/modify/write should be applied. Can be any byte string, including the empty string.
Union field rule. The rule used to determine the column's new latest value from its current latest value. rule can be only one of the following:
append_value bytes Rule specifying that append_value be appended to the existing value. If the targeted cell is unset, it will be treated as containing the empty string.
increment_amount int64 Rule specifying that increment_amount be added to the existing value. If the targeted cell is unset, it will be treated as containing a zero. Otherwise, the targeted cell must contain an 8-byte value (interpreted as a 64-bit big-endian signed integer), or the entire request will fail.

ReadRowsRequest

Request message for Bigtable.ReadRows.

Field name Type Description
table_name string The unique name of the table from which to read. Values are of the form projects/<project>/instances/<instance>/tables/<table>
rows RowSet The row keys and/or ranges to read. If not specified, reads from all rows.
filter RowFilter The filter to apply to the contents of the specified row(s). If unset, reads the entirety of each row.
rows_limit int64 The read will terminate after committing to N rows' worth of results. The default (zero) is to return all results.

ReadRowsResponse

Response message for Bigtable.ReadRows.

Field name Type Description
chunks[] CellChunk
last_scanned_row_key bytes Optionally the server might return the row key of the last row it has scanned. The client can use this to construct a more efficient retry request if needed: any row keys or portions of ranges less than this row key can be dropped from the request. This is primarily useful for cases where the server has read a lot of data that was filtered out since the last committed row key, allowing the client to skip that work on a retry.

CellChunk

Specifies a piece of a row's contents returned as part of the read response stream.

Field name Type Description
row_key bytes The row key for this chunk of data. If the row key is empty, this CellChunk is a continuation of the same row as the previous CellChunk in the response stream, even if that CellChunk was in a previous ReadRowsResponse message.
family_name StringValue The column family name for this chunk of data. If this message is not present this CellChunk is a continuation of the same column family as the previous CellChunk. The empty string can occur as a column family name in a response so clients must check explicitly for the presence of this message, not just for family_name.value being non-empty.
qualifier BytesValue The column qualifier for this chunk of data. If this message is not present, this CellChunk is a continuation of the same column as the previous CellChunk. Column qualifiers may be empty so clients must check for the presence of this message, not just for qualifier.value being non-empty.
timestamp_micros int64 The cell's stored timestamp, which also uniquely identifies it within its column. Values are always expressed in microseconds, but individual tables may set a coarser granularity to further restrict the allowed values. For example, a table which specifies millisecond granularity will only allow values of timestamp_micros which are multiples of 1000. Timestamps are only set in the first CellChunk per cell (for cells split into multiple chunks).
labels[] string Labels applied to the cell by a RowFilter. Labels are only set on the first CellChunk per cell.
value bytes The value stored in the cell. Cell values can be split across multiple CellChunks. In that case only the value field will be set in CellChunks after the first: the timestamp and labels will only be present in the first CellChunk, even if the first CellChunk came in a previous ReadRowsResponse.
value_size int32 If this CellChunk is part of a chunked cell value and this is not the final chunk of that cell, value_size will be set to the total length of the cell value. The client can use this size to pre-allocate memory to hold the full cell value.

Union field row_status.

row_status can be only one of the following:

reset_row bool Indicates that the client should drop all previous chunks for row_key, as it will be re-read from the beginning.
commit_row bool Indicates that the client can safely process all previous chunks for row_key, as its data has been fully read.

Row

Specifies the complete (requested) contents of a single row of a table. Rows which exceed 256MiB in size cannot be read in full.

Field name Type Description
key bytes The unique key which identifies this row within its table. This is the same key that's used to identify the row in, for example, a MutateRowRequest. May contain any non-empty byte string up to 4KiB in length.
families[] Family May be empty, but only if the entire row is empty. The mutual ordering of column families is not specified.

RowFilter

Takes a row as input and produces an alternate view of the row based on specified rules. For example, a RowFilter might trim down a row to include just the cells from columns matching a given regular expression, or might return all the cells of a row but not their values. More complicated filters can be composed out of these components to express requests such as, "within every column of a particular family, give just the two most recent cells which are older than timestamp X."

There are two broad categories of RowFilters (true filters and transformers), as well as two ways to compose simple filters into more complex ones (chains and interleaves). They work as follows:

  • True filters alter the input row by excluding some of its cells wholesale from the output row. An example of a true filter is the value_regex_filter, which excludes cells whose values don't match the specified pattern. All regex true filters use RE2 syntax (https://github.com/google/re2/wiki/Syntax) in raw byte mode (RE2::Latin1), and are evaluated as full matches. An important point to keep in mind is that RE2(.) is equivalent by default to RE2([^\n]), meaning that it does not match newlines. When attempting to match an arbitrary byte, you should therefore use the escape sequence \C, which may need to be further escaped as \\C in your client language.

  • Transformers alter the input row by changing the values of some of its cells in the output, without excluding them completely. Currently, the only supported transformer is the strip_value_transformer, which replaces every cell's value with the empty string.

  • Chains and interleaves are described in more detail in the RowFilter.Chain and RowFilter.Interleave documentation.

The total serialized size of a RowFilter message must not exceed 4096 bytes, and RowFilters may not be nested within each other (in Chains or Interleaves) to a depth of more than 20.

Field name Type Description
Union field filter. Which of the possible RowFilter types to apply. If none are set, this RowFilter returns all cells in the input row. filter can be only one of the following:
chain Chain Applies several RowFilters to the data in sequence, progressively narrowing the results.
interleave Interleave Applies several RowFilters to the data in parallel and combines the results.
condition Condition Applies one of two possible RowFilters to the data based on the output of a predicate RowFilter.
sink bool

ADVANCED USE ONLY. Hook for introspection into the RowFilter. Outputs all cells directly to the output of the read rather than to any parent filter. Consider the following example:

Chain(
  FamilyRegex("A"),
  Interleave(
    All(),
    Chain(Label("foo"), Sink())
  ),
  QualifierRegex("B")
)

                    A,A,1,w
                    A,B,2,x
                    B,B,4,z
                       |
                FamilyRegex("A")
                       |
                    A,A,1,w
                    A,B,2,x
                       |
          +------------+-------------+
          |                          |
        All()                    Label(foo)
          |                          |
       A,A,1,w              A,A,1,w,labels:[foo]
       A,B,2,x              A,B,2,x,labels:[foo]
          |                          |
          |                        Sink() --------------+
          |                          |                  |
          +------------+      x------+          A,A,1,w,labels:[foo]
                       |                        A,B,2,x,labels:[foo]
                    A,A,1,w                             |
                    A,B,2,x                             |
                       |                                |
               QualifierRegex("B")                      |
                       |                                |
                    A,B,2,x                             |
                       |                                |
                       +--------------------------------+
                       |
                    A,A,1,w,labels:[foo]
                    A,B,2,x,labels:[foo]  // could be switched
                    A,B,2,x               // could be switched

Despite being excluded by the qualifier filter, a copy of every cell that reaches the sink is present in the final result.

As with an Interleave, duplicate cells are possible, and appear in an unspecified mutual order. In this case we have a duplicate with column "A:B" and timestamp 2, because one copy passed through the all filter while the other was passed through the label and sink. Note that one copy has label "foo", while the other does not.

Cannot be used within the predicate_filter, true_filter, or false_filter of a Condition.

pass_all_filter bool Matches all cells, regardless of input. Functionally equivalent to leaving filter unset, but included for completeness.
block_all_filter bool Does not match any cells, regardless of input. Useful for temporarily disabling just part of a filter.
row_key_regex_filter bytes Matches only cells from rows whose keys satisfy the given RE2 regex. In other words, passes through the entire row when the key matches, and otherwise produces an empty row. Note that, since row keys can contain arbitrary bytes, the \C escape sequence must be used if a true wildcard is desired. The . character will not match the new line character \n, which may be present in a binary key.
row_sample_filter double Matches all cells from a row with probability p, and matches no cells from the row with probability 1-p.
family_name_regex_filter string Matches only cells from columns whose families satisfy the given RE2 regex. For technical reasons, the regex must not contain the : character, even if it is not being used as a literal. Note that, since column families cannot contain the new line character \n, it is sufficient to use . as a full wildcard when matching column family names.
column_qualifier_regex_filter bytes Matches only cells from columns whose qualifiers satisfy the given RE2 regex. Note that, since column qualifiers can contain arbitrary bytes, the \C escape sequence must be used if a true wildcard is desired. The . character will not match the new line character \n, which may be present in a binary qualifier.
column_range_filter ColumnRange Matches only cells from columns within the given range.
timestamp_range_filter TimestampRange Matches only cells with timestamps within the given range.
value_regex_filter bytes Matches only cells with values that satisfy the given regular expression. Note that, since cell values can contain arbitrary bytes, the \C escape sequence must be used if a true wildcard is desired. The . character will not match the new line character \n, which may be present in a binary value.
value_range_filter ValueRange Matches only cells with values that fall within the given range.
cells_per_row_offset_filter int32 Skips the first N cells of each row, matching all subsequent cells. If duplicate cells are present, as is possible when using an Interleave, each copy of the cell is counted separately.
cells_per_row_limit_filter int32 Matches only the first N cells of each row. If duplicate cells are present, as is possible when using an Interleave, each copy of the cell is counted separately.
cells_per_column_limit_filter int32 Matches only the most recent N cells within each column. For example, if N=2, this filter would match column foo:bar at timestamps 10 and 9, skip all earlier cells in foo:bar, and then begin matching again in column foo:bar2. If duplicate cells are present, as is possible when using an Interleave, each copy of the cell is counted separately.
strip_value_transformer bool Replaces each cell's value with the empty string.
apply_label_transformer string

Applies the given label to all cells in the output row. This allows the client to determine which results were produced from which part of the filter.

Values must be at most 15 characters in length, and match the RE2 pattern [a-z0-9\\-]+

Due to a technical limitation, it is not currently possible to apply multiple labels to a cell. As a result, a Chain may have no more than one sub-filter which contains a apply_label_transformer. It is okay for an Interleave to contain multiple apply_label_transformers, as they will be applied to separate copies of the input. This may be relaxed in the future.

Chain

A RowFilter which sends rows through several RowFilters in sequence.

Field name Type Description
filters[] RowFilter The elements of "filters" are chained together to process the input row: in row -> f(0) -> intermediate row -> f(1) -> ... -> f(N) -> out row The full chain is executed atomically.

Condition

A RowFilter which evaluates one of two possible RowFilters, depending on whether or not a predicate RowFilter outputs any cells from the input row.

IMPORTANT NOTE: The predicate filter does not execute atomically with the true and false filters, which may lead to inconsistent or unexpected results. Additionally, Condition filters have poor performance, especially when filters are set for the false condition.

Field name Type Description
predicate_filter RowFilter If predicate_filter outputs any cells, then true_filter will be evaluated on the input row. Otherwise, false_filter will be evaluated.
true_filter RowFilter The filter to apply to the input row if predicate_filter returns any results. If not provided, no results will be returned in the true case.
false_filter RowFilter The filter to apply to the input row if predicate_filter does not return any results. If not provided, no results will be returned in the false case.

Interleave

A RowFilter which sends each row to each of several component RowFilters and interleaves the results.

Field name Type Description
filters[] RowFilter

The elements of "filters" all process a copy of the input row, and the results are pooled, sorted, and combined into a single output row. If multiple cells are produced with the same column and timestamp, they will all appear in the output row in an unspecified mutual order. Consider the following example, with three filters:

                             input row
                                 |
       -----------------------------------------------------
       |                         |                         |
      f(0)                      f(1)                      f(2)
       |                         |                         |
1: foo,bar,10,x             foo,bar,10,z              far,bar,7,a
2: foo,blah,11,z            far,blah,5,x              far,blah,5,x
       |                         |                         |
       -----------------------------------------------------

All interleaved filters are executed atomically.

RowRange

Specifies a contiguous range of rows.

Field name Type Description
Union field start_key. The row key at which to start the range. If neither field is set, interpreted as the empty string, inclusive. start_key can be only one of the following:
start_key_closed bytes Used when giving an inclusive lower bound for the range.
start_key_open bytes Used when giving an exclusive lower bound for the range.
Union field end_key. The row key at which to end the range. If neither field is set, interpreted as the infinite row key, exclusive. end_key can be only one of the following:
end_key_open bytes Used when giving an inclusive upper bound for the range.
end_key_closed bytes Used when giving an exclusive upper bound for the range.

RowSet

Specifies a non-contiguous set of rows.

Field name Type Description
row_keys[] bytes Single rows included in the set.
row_ranges[] RowRange Contiguous row ranges included in the set.

SampleRowKeysRequest

Request message for Bigtable.SampleRowKeys.

Field name Type Description
table_name string The unique name of the table from which to sample row keys. Values are of the form projects/<project>/instances/<instance>/tables/<table>

SampleRowKeysResponse

Response message for Bigtable.SampleRowKeys.

Field name Type Description
row_key bytes Sorted streamed sequence of sample row keys in the table. The table might have contents before the first row key in the list and after the last one, but a key containing the empty string indicates "end of table" and will be the last response given, if present. Note that row keys in this list may not have ever been written to or read from, and users should therefore not make any assumptions about the row key structure that are specific to their use case.
offset_bytes int64 Approximate total storage space used by all rows in the table which precede row_key. Buffering the contents of all rows between two subsequent samples would require space roughly equal to the difference in their offset_bytes fields.

TimestampRange

Specified a contiguous range of microsecond timestamps.

Field name Type Description
start_timestamp_micros int64 Inclusive lower bound. If left empty, interpreted as 0.
end_timestamp_micros int64 Exclusive upper bound. If left empty, interpreted as infinity.

ValueRange

Specifies a contiguous range of raw byte values.

Field name Type Description
Union field start_value. The value at which to start the range. If neither field is set, interpreted as the empty string, inclusive. start_value can be only one of the following:
start_value_closed bytes Used when giving an inclusive lower bound for the range.
start_value_open bytes Used when giving an exclusive lower bound for the range.
Union field end_value. The value at which to end the range. If neither field is set, interpreted as the infinite string, exclusive. end_value can be only one of the following:
end_value_closed bytes Used when giving an inclusive upper bound for the range.
end_value_open bytes Used when giving an exclusive upper bound for the range.
