----------------------------------
Summary: mongodb sdk
MongoDbIO.BoundedMongoDbSource.splitKeysToFilters incorrect
Key: BEAM-2256
URL: https://issues.apache.org/jira/browse/BEAM-2256
Project: Beam
Issue Type: Bug
Components: sdk-java-extensions
Affects Versions: 0.6.0, 0.5.0, 0.4.0, Not applicable
Reporter: wang hongmin
Assignee: Davor Bonaci
When use beam-sdks-java-io-mongodb to count a large collection in MongoDB, I
always get a smaller number than actual size of the collection. It seems a
puzzle, until I dived into source code and trace the execution. The fault
exists in method MongoDbIO.BoundedMongoDbSource.splitKeysToFilters(), which
should return one more FILTER than size of input argument splitKeys.
I check all version of this file, it seems none was correct.
Additionally, it seems no suitable [Component]. I choose a similar tag.:)
