DanSkells opened a new issue, #54646: URL: https://github.com/apache/spark/issues/54646
In my day job, we came across an issue where we were performing lookups in a map with > 1,000,000 element. After profiling, we realised that the map lookup is a linear scan, and looking to either optimise this or understand if some other library or other programming metaphor exists within Spark. The use case is insertion and lookup, without any need to remove elements. Happy to discuss / work with maintainers if appropriate to address the issue. I have seen the OpenHashMap implementation, but this seems to be a Spark internal implementation, so not sure if this would be an appropriate base to work from. -- This is an automated message from the Apache Git Service.
