Dinesh Joshi commented on CASSANDRA-14482: ------------------------------------------ Adding our own checksumming incurs additional overhead not just in terms of the additional CPU that we would use going over the data twice (once for compression inside Zstd and then once in the compressor to compute the hash) but also additional code and maintaining that code. From my digging around in the code it seems [they're clobbering parameters|https://github.com/facebook/zstd/issues/1534] which should be an easy fix. > ZSTD Compressor support in Cassandra > ------------------------------------ > > Key: CASSANDRA-14482 > URL: https://issues.apache.org/jira/browse/CASSANDRA-14482 > Project: Cassandra > Issue Type: New Feature > Components: Dependencies, Feature/Compression > Reporter: Sushma A Devendrappa > Assignee: Dinesh Joshi > Priority: Major > Labels: performance, pull-request-available > Fix For: 4.x > > Time Spent: 2h 40m > Remaining Estimate: 0h > > ZStandard has a great speed and compression ratio tradeoff. > ZStandard is open source compression from Facebook. > More about ZSTD > [https://github.com/facebook/zstd] > https://code.facebook.com/posts/1658392934479273/smaller-and-faster-data-compression-with-zstandard/ > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
