Class ColumnFamilyMapping

Configuration for writing a Pub/Sub message to a Bigtable row with a user-defined key and writing to column families. If this field is set: - The subscription messages must be formatted as JSON. - The row key mapping is configured in the key_definition section. - The top-level fields will be written either: - By default, they will be written to the data column family with the field name as the column qualifier. - But if the field name matches an existing column family (except for the default data column), then that field will be written to that column family, either as a scalar or its next level nested fields if it's a JSON object. - The cell timestamp will be the message publish timestamp. If the field is not set, the default behavior is to write: - row key: subscription name, message ID hash, and message ID delimited by #. - columns: message bytes written to a single column family data with an empty-string column qualifier. - cell timestamp: the message publish timestamp.
