Class DirectRow (2.17.0)

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')

Row key.

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_row_key] :end-before: [END bigtable_api_row_row_key] :dedent: 4

Row table.

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_table] :end-before: [END bigtable_api_row_table] :dedent: 4

clear()

Removes all currently accumulated mutations on the current row.

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_clear] :end-before: [END bigtable_api_row_clear] :dedent: 4

commit()

Makes a MutateRow API request.

If no mutations have been created in the row, no request is made.

Mutations are applied atomically and in order, meaning that earlier mutations can be masked / negated by later ones. Cells already present in the row are left unchanged unless explicitly changed by a mutation.

After committing the accumulated mutations, resets the local mutations to an empty list.

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_commit] :end-before: [END bigtable_api_row_commit] :dedent: 4

delete()

Deletes this row from the table.

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_delete] :end-before: [END bigtable_api_row_delete] :dedent: 4

delete_cell(column_family_id, column, time_range=None)

Deletes cell in this row.

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_delete_cell] :end-before: [END bigtable_api_row_delete_cell] :dedent: 4

delete_cells(column_family_id, columns, time_range=None)

Deletes cells in this row.

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_delete_cells] :end-before: [END bigtable_api_row_delete_cells] :dedent: 4

get_mutations_size()

Gets the total mutations size for current row

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_get_mutations_size] :end-before: [END bigtable_api_row_get_mutations_size] :dedent: 4

set_cell(column_family_id, column, value, timestamp=None)

Sets a value in this row.

The cell is determined by the row_key of this DirectRow and the column. The column must be in an existing .ColumnFamily (as determined by column_family_id).

.. literalinclude:: snippets_table.py :start-after: [START bigtable_api_row_set_cell] :end-before: [END bigtable_api_row_set_cell] :dedent: 4
