Summary: Optimize streaming path in Cassandra
Key: CASSANDRA-14556
URL: https://issues.apache.org/jira/browse/CASSANDRA-14556
Project: Cassandra
Issue Type: Improvement
Reporter: Dinesh Joshi
Assignee: Dinesh Joshi
During streaming, Cassandra reifies the sstables into objects. This creates
unnecessary garbage and slows down the whole streaming process as some sstables
can be transferred as a whole file rather than individual partitions. The
objective of the ticket is to detect when a whole sstable can be transferred
and skip the object reification. We can also use a zero-copy path to avoid
bringing data into user-space on both sending and receiving side.
