Hi all, Let's start the discussion regarding the partition table.
To support partition table, what we should do? 1. create table with partition to support Range Partitioning, Hash Partitioning, List Partitioning and Composite Partitioning, write the partition info to schema. 2. during data loading, re-partition the input data, start a task process a partition, write partition information to footer and index file. 3. during data query, prune B+Tree by partition if the filter contain the partition column. or prune data blocks by partition when there is only partition column predicate. 4. optimizer the join performance of two partition tables if partition column is the join column. Any thoughts, comments and questions ? Thanks!
