IMPALA-5500: Reduce catalog update topic size Problem: IMPALA-4029 introduced the use of the flatbuffers serialization libary for storing file and block metadata. That change reduced the effectiveness of the Thrift compaction protocol (when --compact_catalog_topic is used), thereby causing a 2X increase in catalog update topic size when the compact protocol is used. Fix: LZ4 compress the catalog topic updates before sent to the statestore when --compact_catalog_topic is set to true. Results: ~4X reduction in catalog update topic size Change-Id: I2f725cd8596205e6101d5b56abf08125faa30b0a Reviewed-on: http://gerrit.cloudera.org:8080/7268 Reviewed-by: Dimitris Tsirogiannis <[email protected]> Tested-by: Impala Public Jenkins --- M be/src/catalog/catalog-server.cc M be/src/catalog/catalog-util.cc M be/src/catalog/catalog-util.h M be/src/service/impala-server.cc A tests/custom_cluster/test_compact_catalog_updates.py 5 files changed, 136 insertions(+), 5 deletions(-) Approvals: Impala Public Jenkins: Verified Dimitris Tsirogiannis: Looks good to me, approved -- To view, visit http://gerrit.cloudera.org:8080/7268 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: merged Gerrit-Change-Id: I2f725cd8596205e6101d5b56abf08125faa30b0a Gerrit-PatchSet: 11 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Dimitris Tsirogiannis <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Dimitris Tsirogiannis <[email protected]> Gerrit-Reviewer: Impala Public Jenkins Gerrit-Reviewer: Tim Armstrong <[email protected]>
