Module column_family (2.16.0)

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A string gc_expression can also be used with API requests, but that value would be superceded by a gc_rule.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
