--------------------------------
Summary: BlockManagerImpl#getBlockByID does unnecessary
serialization
Key: HDDS-4220
URL: https://issues.apache.org/jira/browse/HDDS-4220
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: Ozone Datanode
Reporter: Ethan Rose
Assignee: Ethan Rose
After HDDS-3869, tables in the datanode handle coding/decoding objects to/from
RocksDB, and the caller no longer has to do this manually. As a result, the
BlockManagerImpl#getBlockByID method should now return a BlockData type,
instead of a byte array. In the current implementation, this method converts
the block data into a byte array and returns it to the caller, who then
converts the byte array back to block data in order to use it.
