----------------------------------------------
Summary: Optimize Snapdiff to compute diff from Delta SST Files in
case of DAG based Diff
Key: HDDS-9154
URL: https://issues.apache.org/jira/browse/HDDS-9154
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Swaminathan Balachandran
Assignee: Swaminathan Balachandran
Currently Snapdiff is computed by getting a reverse object id mapping by
reading the Delta sst Files and referring to the src and target snapshot
rocksdb. Instead of computing the diff based on the contents of the sst files
directly based on the internal rocksdb sequence number and value in the sst
file which will save lot of io-ops in the diff computation.
