Jacob Jona Fahlenkamp updated FLINK-37950:
------------------------------------------
Description:
The MongoDB connector is slower than expected. When using MongoDB API directly,
we typically use the ordered(false) option to improve bulk write performance:
[https://www.mongodb.com/docs/drivers/java/sync/current/crud/bulk/#unordered-execution]
The mongodb connector currently doesn't expose this option. It calls bulkWrite
without specifying BulkWriteOptions - hence using default options - here:
[https://github.com/apache/flink-connector-mongodb/blob/main/flink-connector-mongodb/src/main/java/org/apache/flink/connector/mongodb/sink/writer/MongoWriter.java#L216]
The default setting is ordered(true), where mongodb is forced to perform the
bulk operations in sequence.
It would be great if there was a connector option to set this mongodb option.
