Partitioning Under The Hood

Mikael Ronström and Mattias Jonsson worked on implementing and improving partitioning in MySQL. Partitioning allows tables to be broken into smaller pieces (partitions) that can improve performance by making queries faster and reducing locking overhead. The implementation involves a partitioning handler that directs queries to individual partitions while supporting pruning to avoid scanning irrelevant partitions. Future work may include moving partitions between tables and improving locking to further optimize queries on partitioned tables.
