Ma Jian created HUDI-7291: ----------------------------- Summary: 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
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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
