Change subject: IMPALA-5500: Reduce catalog update topic size ...................................................................... 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.
