Module column_family (2.13.2)

User friendly container for Google Cloud Bigtable Column Family.

  ColumnFamily 
 ( 
 column_family_id 
 , 
 table 
 , 
 gc_rule 
 = 
 None 
 ) 
 

Representation of a Google Cloud Bigtable Column Family.

We can use a ColumnFamily to:

• create itself
• update itself
• delete itself

  GCRuleIntersection 
 ( 
 rules 
 ) 
 

Intersection of garbage collection rules.

For example:

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

  GCRuleUnion 
 ( 
 rules 
 ) 
 

Union of garbage collection rules.

For example:

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

  GarbageCollectionRule 
 () 
 

Garbage collection rule for column families within a table.

Cells in the column family (within a table) fitting the rule will be deleted during garbage collection.

A string gc_expression can also be used with API requests, but that value would be superceded by a gc_rule . As a result, we don't support that feature and instead support via native classes.

  MaxAgeGCRule 
 ( 
 max_age 
 ) 
 

Garbage collection limiting the age of a cell.

For example:

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

  MaxVersionsGCRule 
 ( 
 max_num_versions 
 ) 
 

Garbage collection limiting the number of versions of a cell.

For example:

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