Open tsinan opened 2 years ago

tsinan commented 2 years ago

When use prestosql to query carbondata, the lucene index can be used to prune blocklet? (Like 'TEXT_MATCH')

Thanks.

@tsinan 1)Create lucene index is not support from presto 2) Read lucene index support is there [You need to create lucene index from spark]

@maheshrajus Thanks for your reply. "2) Read lucene index support is there" When I use "TEXT_MATCH" in prestosql, prestosql prompts that "TEXT_MATCH" is not supported. I searched the source code under the integration/presto/... directory, but did not find the relevant source code. Which document describes the specific method of using lucene index by prestosql? Or some details can be found in which file of the source code. thank you very much.
