> Thats interesting that dashmap performed better. Would you mind also doing a query with a filter / pruning involved and comparing the results (perhaps with a range scan as well)? And just to confirm, the cache is filled at creation time during schema inference, right? > > Also is the cache used by both `ListingTable` and `ParquetExec`? Im not sure how it works if adding the cache removes currently used by ListingTable the duplicate calls or if additional work is required for that (if it's additional work could probably be done as a separate PR once cache implementation is finalized). Yes, could you give me some review advice if you are available to see if I implement it right? The closed PR is SequenceTrie and the draft PR is DashMap > > I think it would also be nice to have a new benchmark for this to help monitor moving forward. I want to do it, too, but I could not find a suitable open-source dataset for it. Currently, I am using bitcoin. -- This is an automated message from the Apache Git Service.
