Module row (2.18.1)

User-friendly container for Google Cloud Bigtable Row.

  AppendRow 
 ( 
 row_key 
 , 
 table 
 ) 
 

Google Cloud Bigtable Row for sending append mutations.

These mutations are intended to augment the value of an existing cell and uses the methods:

• append_cell_value
• increment_cell_value

The first works by appending bytes and the second by incrementing an integer (stored in the cell as 8 bytes). In either case, if the cell is empty, assumes the default empty value (empty string for bytes or 0 for integer).

  Cell 
 ( 
 value 
 , 
 timestamp_micros 
 , 
 labels 
 = 
 None 
 ) 
 

Representation of a Google Cloud Bigtable Cell.

  ConditionalRow 
 ( 
 row_key 
 , 
 table 
 , 
 filter_ 
 ) 
 

Google Cloud Bigtable Row for sending mutations conditionally.

Each mutation has an associated state: :data: True or :data: False . When commit -ed, the mutations for the :data: True state will be applied if the filter matches any cells in the row, otherwise the :data: False state will be applied.

A ConditionalRow accumulates mutations in the same way a DirectRow does:

• set_cell
• delete
• delete_cell
• delete_cells

with the only change the extra state parameter::

row_cond = table.row(b'row-key2', filter_=row_filter) row_cond.set_cell(u'fam', b'col', b'cell-val', state=True) row_cond.delete_cell(u'fam', b'col', state=False)

  DirectRow 
 ( 
 row_key 
 , 
 table 
 = 
 None 
 ) 
 

Google Cloud Bigtable Row for sending "direct" mutations.

These mutations directly set or delete cell contents:

• set_cell
• delete
• delete_cell
• delete_cells

These methods can be used directly::

row = table.row(b'row-key1') row.set_cell(u'fam', b'col1', b'cell-val') row.delete_cell(u'fam', b'col2')

Exception raised to invalid chunk data from back-end.

  PartialRowData 
 ( 
 row_key 
 ) 
 

Representation of partial row in a Google Cloud Bigtable Table.

These are expected to be updated directly from a ._generated.bigtable_service_messages_pb2.ReadRowsResponse

  Row 
 ( 
 row_key 
 , 
 table 
 = 
 None 
 ) 
 

Base representation of a Google Cloud Bigtable Row.

This class has three subclasses corresponding to the three RPC methods for sending row mutations:

• DirectRow for MutateRow
• ConditionalRow for CheckAndMutateRow
• AppendRow for ReadModifyWriteRow
