> Pushing Down Partition Pruning Conditions to Column Stats During Data Skipping
> ------------------------------------------------------------------------------

> Key: HUDI-7291
> URL: https://issues.apache.org/jira/browse/HUDI-7291
> Project: Apache Hudi
> Issue Type: Improvement
> Reporter: Ma Jian
> Priority: Major
> Labels: pull-request-available
>
> In the current implementation of data skipping, column statistics for the
> entire table are read and then subjected to data skipping filtering
> operations based on these stats. When the table has a large volume of data
> and a high number of partitions, this approach can reduce the efficiency of
> data skipping, as partition pruning conditions are not utilized.
> By pushing down the conditions for partition filtering to after the column
> statistics are read and applying pruning at that point, the size of the
> column stats that are subsequently involved in data skipping will be
> significantly reduced. This not only saves time on later computations but
> also conserves memory.
