Example 1 with FileCompactStrategy

use of org.apache.flink.connector.file.sink.compactor.FileCompactStrategy in project flink by apache.

the class FileSink method addPreCommitTopology.

        // coordinator and the compactor operators.

    // parallelism of the compactors is not configurable at present, since it must be identical
    // to that of the committers, or the committable summary and the committables may be
    // distributed to different committers, which will cause a failure
