Cheng Lian updated SPARK-6759: ------------------------------ Priority: Critical (was: Major) > Do not borrow/release a kryo instance for every value in a complex type value > when doing serialization/deserialization in in-memory columnar store > -------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: SPARK-6759 > URL: https://issues.apache.org/jira/browse/SPARK-6759 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Yin Huai > Priority: Critical > > Right now, for columns of map, array, and struct types, we borrow/release a > kryo instance when serializing/deserializing every value, which is really > expensive (the kryo pool is backed by a ArrayBlockingQueue). It will be good > if we borrow before the serialization/deserialization and release it after we > have done all of the work. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
