I remember you telling me that you had 500+ columns. Its known that you could see a perf hit w/ such large columns and since hudi builds col stats index for all columns. Suggestion here is to disable col stats and re-build w/ just a few cols. Step1: you can disable col stats fully hoodie.metadata.index.column.stats.enable = false. So during your next write, hudi will clean up entire col stats partition in metadata table. Step2: after few commits, you can re-enable col stats for your table, by explicitly setting cols to index. `hoodie.metadata.index.column.stats.enable=true` and by setting appropriate value for hoodie.metadata.index.column.stats.column.list your first commit with this new set of configs might hav e some higher latency since it bootstraps entire col stats for your table. After this, you should be able to leverage col stats in your queries. -- This is an automated message from the Apache Git Service.
