Class DirectRow (0.34.0)

  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_row_row_key] :end-before: [END bigtable_row_row_key]

Row table.

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_row_table] :end-before: [END bigtable_row_table]

  clear 
 () 
 

Removes all currently accumulated mutations on the current row.

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_row_clear] :end-before: [END bigtable_row_clear]

  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_row_commit] :end-before: [END bigtable_row_commit]

  delete 
 () 
 

Deletes this row from the table.

.. literalinclude:: snippets_table.py :start-after: [START bigtable_row_delete] :end-before: [END bigtable_row_delete]

  delete_cell 
 ( 
 column_family_id 
 , 
 column 
 , 
 time_range 
 = 
 None 
 ) 
 

Deletes cell in this row.

.. literalinclude:: snippets_table.py :start-after: [START bigtable_row_delete_cell] :end-before: [END bigtable_row_delete_cell]

  delete_cells 
 ( 
 column_family_id 
 , 
 columns 
 , 
 time_range 
 = 
 None 
 ) 
 

Deletes cells in this row.

.. literalinclude:: snippets_table.py :start-after: [START bigtable_row_delete_cells] :end-before: [END bigtable_row_delete_cells]

  get_mutations_size 
 () 
 

Gets the total mutations size for current row

For example:

.. literalinclude:: snippets_table.py :start-after: [START bigtable_row_get_mutations_size] :end-before: [END bigtable_row_get_mutations_size]

  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_row_set_cell] :end-before: [END bigtable_row_set_cell]
