Sean Owen updated SPARK-12060: ------------------------------ Fix Version/s: (was: 1.6.0) > Avoid memory copy in JavaSerializerInstance.serialize > ----------------------------------------------------- > > Key: SPARK-12060 > URL: https://issues.apache.org/jira/browse/SPARK-12060 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Shixiong Zhu > Assignee: Shixiong Zhu > Priority: Critical > > JavaSerializerInstance.serialize uses ByteArrayOutputStream.toByteArray to > get the serialized data. ByteArrayOutputStream.toByteArray needs to copy the > content in the internal array to a new array. However, since the array will > be converted to ByteBuffer at once, we can avoid the memory copy. -- 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
