Apache Spark commented on SPARK-9411: ------------------------------------- User 'JoshRosen' has created a pull request for this issue: https://github.com/apache/spark/pull/7741 > Make page size configurable > --------------------------- > > Key: SPARK-9411 > URL: https://issues.apache.org/jira/browse/SPARK-9411 > Project: Spark > Issue Type: Improvement > Reporter: Reynold Xin > Assignee: Josh Rosen > Priority: Critical > > We need to make page sizes configurable so we can reduce them in unit tests > and increase them in real production workloads. > The following hardcoded page sizes need to be updated: > - Spark Core: UnsafeShuffleExternalSorter.PAGE_SIZE > - Spark SQL: UnsafeExternalSorter.PAGE_SIZE > - Unsafe: BytesToBytesMap.PAGE_SIZE_BYTES > While updating the page sizes, we should also update certain size > calculations which are based on the page size so that they do not assume that > all pages are the same size. This isn't strictly necessary in this patch but > should be done eventually as part of supporting overflow pages for large > records. > A number of unit tests also need to be updated to account for the new page > sizes. -- 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
