rkhachatryan opened a new pull request #12362:
URL: https://github.com/apache/flink/pull/12362
## What is the purpose of the change
With Unaligned Checkpoints enabled, channel state is written to the file
system. If the underlying state handle is shared between multiple handles, they
should report their size according to offsets.
Currently, each handle reports the size of the underlying handle, therefore
multiplying total state size in reports.
This PR stores state size explicitly in each handle.
## Verifying this change
This change added tests and can be verified as follows: added
`ChannelStateCheckpointWriterTest.testFileHandleSize`.
