Prasanth Jayachandran commented on HIVE-19211:
----------------------------------------------
For static partitions locks are acquired for specific partition. For dynamic
partition, only table level shared lock is acquired and the property
setIsDynamicPartitionWrite() is set on the lock component builder (not sure if
this alone is sufficient). For dynamic partition case, do we still have to
acquire lock per partition?
> New streaming ingest API and support for dynamic partitioning
