Hello, Checkpointing is enabled and works fine if configured parquet page size is at least 64 bytes as otherwise there is exception thrown at back-end.
Looks to be an issue which is not handled by file sink bulk writer?

By default, write parquet files will roll a new file when checkpointing.

If configured parquet page size as low as 1 byte (allowed configuration) then flink keeps on creating multiple ‘in-progress’ state files and with content only as ‘PAR1’ and never closed the file. I want to know what is the reason of not closing the file and creating multiple ‘in-progress’ part files or why no error is given if applicable? Rgds, Kamal
