Cloud Bigtable V2 API - Class Google::Cloud::Bigtable::V2::RowFilter (v1.5.0)

Reference documentation and code samples for the Cloud Bigtable V2 API class Google::Cloud::Bigtable::V2::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 20480 bytes, and RowFilters may not be nested within each other (in Chains or Interleaves) to a depth of more than 20.

#apply_label_transformer

def apply_label_transformer() -> ::String

Returns

(::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.

Note: The following fields are mutually exclusive: apply_label_transformer, chain, interleave, condition, sink, pass_all_filter, block_all_filter, row_key_regex_filter, row_sample_filter, family_name_regex_filter, column_qualifier_regex_filter, column_range_filter, timestamp_range_filter, value_regex_filter, value_range_filter, cells_per_row_offset_filter, cells_per_row_limit_filter, cells_per_column_limit_filter, strip_value_transformer. If a field in that set is populated, all other fields in the set will automatically be cleared.

#row_key_regex_filter

def row_key_regex_filter() -> ::String

Returns

(::String) — 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.

#sink

def sink() -> ::Boolean

Returns

(::Boolean) — 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(

  Interleave(
    All(),

       A,A,1,w              A,A,1,w,labels:[foo]
       A,B,2,x              A,B,2,x,labels:[foo]

          +------------+      x------+          A,A,1,w,labels:[foo]
                       |                        A,B,2,x,labels:[foo]

                    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.

Note: The following fields are mutually exclusive: sink, chain, interleave, condition, pass_all_filter, block_all_filter, row_key_regex_filter, row_sample_filter, family_name_regex_filter, column_qualifier_regex_filter, column_range_filter, timestamp_range_filter, value_regex_filter, value_range_filter, cells_per_row_offset_filter, cells_per_row_limit_filter, cells_per_column_limit_filter, strip_value_transformer, apply_label_transformer. If a field in that set is populated, all other fields in the set will automatically be cleared.

def value_regex_filter() -> ::String

Returns

(::String) — 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.

Note: The following fields are mutually exclusive: value_regex_filter, chain, interleave, condition, sink, pass_all_filter, block_all_filter, row_key_regex_filter, row_sample_filter, family_name_regex_filter, column_qualifier_regex_filter, column_range_filter, timestamp_range_filter, value_range_filter, cells_per_row_offset_filter, cells_per_row_limit_filter, cells_per_column_limit_filter, strip_value_transformer, apply_label_transformer. If a field in that set is populated, all other fields in the set will automatically be cleared.
