Stream
Constructors
Properties
AppendOnly mode defines that the stream of changes (INSERT, UPDATE-INSERT, UPDATE-DELETE and DELETE events) to a source table will be written to the destination Google BigQuery table, retaining the historical state of the data.
The guaranteed data freshness (in seconds) when querying tables created by the stream. Editing this field will only affect new tables created in the future, but existing tables will not be impacted. Lower values mean that queries will return fresher data, but may result in higher cost. A duration in seconds with up to nine fractional digits, terminated by 's'. Example: "3.5s". Defaults to 900s.
Merge mode defines that all changes to a table will be merged at the destination Google BigQuery table. This is the default write mode. When selected, BigQuery reflects the way the data is stored in the source database. With Merge mode, no historical record of the change events is kept.
A single target dataset to which all data will be streamed. Structure is documented below.
Destination datasets are created so that hierarchy of the destination data objects matches the source hierarchy. Structure is documented below.
