Reynold Xin resolved SPARK-3135. -------------------------------- Resolution: Fixed Fix Version/s: 1.2.0 Assignee: Reynold Xin > Avoid memory copy in TorrentBroadcast serialization > --------------------------------------------------- > > Key: SPARK-3135 > URL: https://issues.apache.org/jira/browse/SPARK-3135 > Project: Spark > Issue Type: Sub-task > Reporter: Reynold Xin > Assignee: Reynold Xin > Labels: starter > Fix For: 1.2.0 > > > TorrentBroadcast.blockifyObject uses a ByteArrayOutputStream to serialize > broadcast object into a single giant byte array, and then separates it into > smaller chunks. We should implement a new OutputStream that writes > serialized bytes directly into chunks of byte arrays so we don't need the > extra 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
