> Table Store sink continuously fails with "Trying to add file which is already
> added" when snapshot committing is slow.
> This is due to a bug in {{FileStoreCommitImpl#filterCommitted}}. When this
> method finds an identifier, it removes the identifier from a map. However
> different snapshots may have the same identifier (for example an APPEND
> commit and the following COMPACT commit will have the same identifier), so we
> need to use another set to check for identifiers.
> When snapshot committing is fast there is at most 1 identifier to check after
> the job restarts, so nothing happens. However when snapshot committing is
> slow, there will be multiple identifiers to check and some identifiers will
> be mistakenly kept.
