> Currently, in [SyncUtilHelpers|https://github.com/apache/hudi/blob/a2db1a9363a68d0dacc7f2970f37f016aefc2951/hudi-sync/hudi-sync-common/src/main/java/org/apache/hudi/sync/common/util/SyncUtilHelpers.java#L56] runHoodieMetaSync is synchronized. This was done to make access thread-safe. However, for multi-table deltastreamers, syncs running for different tables from the same driver would frequently block. We can introduce a fine-grained concurrency control by taking a lock only for base path/sync tool class.
