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: Snappy 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 --- M be/src/catalog/catalog-server.cc M be/src/catalog/catalog-server.h M be/src/service/impala-server.cc M be/src/service/impala-server.h A tests/custom_cluster/test_compact_catalog_updates.py 5 files changed, 143 insertions(+), 6 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/68/7268/4 -- To view, visit http://gerrit.cloudera.org:8080/7268 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: I2f725cd8596205e6101d5b56abf08125faa30b0a Gerrit-PatchSet: 4 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Dimitris Tsirogiannis <dtsirogian...@cloudera.com> Gerrit-Reviewer: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Dimitris Tsirogiannis <dtsirogian...@cloudera.com>
