Swaminathan Balachandran updated HDDS-14166:
--------------------------------------------
Description: Completely get rid of byte array operations for PUT and DELETE
from RDBBatchOperation. A direct byte buffer copy can be still performed even
if a byte array is sent from the table interface. Since the underlying rocksdb
interface is going to perform the same buffer copy on the JNI side i.e. copying
heap to off heap memory. Thus it would be more optimal to just copy it to
direct byte buffer and get rid of the byte array for gc. This directByteBuffer
can be now used for ByteWise comparisons which would be much faster on the
native side done in HDDS-14238 (was: In this JIRA, we will add a
deleteWithBatch method using RocksDB ByteBuffer APIs.)
