Expand description
Track whether or not we should skip a specific debezium message
The goal of deduplication is to omit sending true duplicates – the exact same record being sent into materialize twice. That means that we create one deduplicator per timely worker and use use timely key sharding normally. But it also means that no single deduplicator knows the highest-ever seen binlog offset.
Fields§
§last_position: Option<RowCoordinates>
Last recorded binlog position.
DebeziumEnvelope
determines whether messages that are not ahead
of the last recorded position will be skipped.
messages_processed: MzOffset
§filenames_to_indices: BTreeMap<String, u64>
§projection: DebeziumDedupProjection
