Method Detail

getSnapshotChangeEventSource

SnapshotChangeEventSource getSnapshotChangeEventSource(OffsetContext offsetContext,
                                                       SnapshotProgressListener snapshotProgressListener)

Returns a snapshot change event source that may emit change events for schema and/or data changes. Depending on the snapshot mode, a given source may decide to do nothing at all if a previous offset is given. In this case it should return that given offset context from its StreamingChangeEventSource.execute(io.debezium.pipeline.source.spi.ChangeEventSource.ChangeEventSourceContext) method.

Parameters:

offsetContext - A context representing a restored offset from an earlier run of this connector. May be null.

snapshotProgressListener - A listener called for changes in the state of snapshot. May be null.

Returns:

A snapshot change event source

getStreamingChangeEventSource

StreamingChangeEventSource getStreamingChangeEventSource(OffsetContext offsetContext)

Returns a streaming change event source that starts streaming at the given offset.
