When UseRESTCatalogCommit(true) is set, FileStoreCommit does not write snapshot files to the filesystem — it delegates the final commit to the REST catalog server. The object store restriction (which exists because atomic rename is not supported on object stores) does not apply in this mode since no snapshot file needs to be atomically written. This allows external catalog integrations (e.g., DLF) to use FileStoreCommit with oss:// table paths without needing the "enable-object-store-commit-in-inte-test" workaround flag.

Purpose
When
UseRESTCatalogCommit(true)is set,FileStoreCommitdelegates the final snapshot commit to the REST catalog server instead of writing the snapshot file to the filesystem. The existing object store restriction (which blocks commit onoss://,s3://, etc.) exists because atomic rename is not supported on object stores — but this restriction does not apply in REST commit mode since no snapshot file needs to be atomically written by the client.Currently, external catalog integrations that use
UseRESTCatalogCommit(true)with object store table paths are forced to set the internal test flagenable-object-store-commit-in-inte-testto bypass this check. This PR relaxes the constraint so thatUseRESTCatalogCommit(true)alone is sufficient.Changes
file_store_commit.cpp: Added!ctx->UseRESTCatalogCommit()to the object store check condition, so REST commit mode skips the restriction.Tests
TestObjectStoreBlockedWithoutRESTCommit: Verifies that non-REST commit mode still correctly identifies object store vs. local paths viaFileSystem::IsObjectStore().TestRESTCatalogCommitWithObjectStorePath: Verifies that REST commit mode works end-to-end (Create → Commit → GetLastCommitTableRequest) and does not write snapshot files to the filesystem.All 30 existing
FileStoreCommitImplTesttests continue to pass.
