public BigtableOptions.Builder setColumnFamilies(List<BigtableColumnFamily> columnFamilies)
List of column families to expose in the table schema along with their types.
This list restricts the column families that can be referenced in queries and specifies
their value types. You can use this list to do type conversions - see the 'type' field for
more details. If you leave this list empty, all column families are present in the table
schema and their values are read as BYTES. During a query only the column families referenced
in that query are read from Bigtable.
public BigtableOptions.Builder setIgnoreUnspecifiedColumnFamilies(Boolean ignoreUnspecifiedColumnFamilies)
If field is true, then the column families that are not specified in columnFamilies list are
not exposed in the table schema. Otherwise, they are read with BYTES type values. The default
value is false.
public BigtableOptions.Builder setReadRowkeyAsString(Boolean readRowkeyAsString)
If readRowkeyAsString is true, then the rowkey column families will be read and converted to
string. Otherwise they are read with BYTES type values and users need to manually cast them
with CAST if necessary. The default value is false.
