[jira] [Commented] (SPARK-31463) Enhance JsonDataSource by replacing jackson with simdjson
[ https://issues.apache.org/jira/browse/SPARK-31463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17091389#comment-17091389 ] Maxim Gekk commented on SPARK-31463: Parsing itself takes 10-20%. JSON datasource spends significant time in conversions to desired types according to schema. Even if you improve performance of parsing by a few times, the total impact will be not so significant. > Enhance JsonDataSource by replacing jackson with simdjson > - > > Key: SPARK-31463 > URL: https://issues.apache.org/jira/browse/SPARK-31463 > Project: Spark > Issue Type: Improvement > Components: SQL >Affects Versions: 3.0.0 >Reporter: Steven Moy >Priority: Minor > > I came across this VLDB paper: [https://arxiv.org/pdf/1902.08318.pdf] on how > to improve json reading speed.

I was following SQLite and DuckDB, their approach is to inline the dependency (bring the code in in the case of compatible license). Or would it better to support simdjson as a compeletely separate DataSourcev2 implementation? simdjson license is Apache License as well; [https://github.com/simdjson/simdjson/blob/master/LICENSE] > Enhance JsonDataSource by replacing jackson with simdjson > - > > Key: SPARK-31463 > URL: https://issues.apache.org/jira/browse/SPARK-31463 > Project: Spark > Issue Type: Improvement > Components: SQL >Affects Versions: 3.0.0 >Reporter: Steven Moy >Priority: Minor > > I came across this VLDB paper: [https://arxiv.org/pdf/1902.08318.pdf] on how > to improve json reading speed.

I think [~maxgekk] talked about vectorization somewhere. My biggest concern is that if it's right to bring the C library into Spark as a dependency or not. > Enhance JsonDataSource by replacing jackson with simdjson > - > > Key: SPARK-31463 > URL: https://issues.apache.org/jira/browse/SPARK-31463 > Project: Spark > Issue Type: Improvement > Components: SQL >Affects Versions: 3.0.0 >Reporter: Steven Moy >Priority: Minor > > I came across this VLDB paper: [https://arxiv.org/pdf/1902.08318.pdf] on how > to improve json reading speed.
