Interface ChangeStreamRecordAdapter<ChangeStreamRecordT>

All Known Implementing Classes:
DefaultChangeStreamRecordAdapter
@InternalApi("Intended for use by the BigtableIO in apache/beam only.") public interface ChangeStreamRecordAdapter<ChangeStreamRecordT>
An extension point that allows end users to plug in a custom implementation of logical change stream records. This is useful in cases where the user would like to apply advanced client side filtering(for example, only keep DeleteFamily in the mutations). This adapter acts like a factory for a SAX style change stream record builder.
