> Key: HUDI-3760
> URL: https://issues.apache.org/jira/browse/HUDI-3760
> Project: Apache Hudi
> Issue Type: Bug
> Reporter: Alexey Kudinkin

> Priority: Blocker

> Fix For: 0.11.0
>
>
> Right now all the records from ColStats for _all columns,_ for _all files_
> are being read to compose the index used in Data Skipping.
> In reality, individual queries touch up only a handful of columns at any
> given moment, so we can very effectively prune the # of records we fetch
> simply fetching records for the columns referenced in the query (by the key
> prefix, since CS record key is concatenation of column, partition-path,
> filename)
