Partitioning Performance. One Giant Leap For SQL: MySQL 8.0 Released; Forums. For information on partitioning restrictions and feature limitations, see Section 18.5, "Restrictions and Limitations on Partitioning".. As a database grows exponentially, then some queries (even the optimized one) are getting slower. Partitioning increases query performance, which means when you query, you will only have to look at a subset of the data to get a result rather than whole table. – No, MySQL uses a pruning algorithm and is not parallel – Good partitioning design is required to benefit from pruning, concentrate on aligning query filters to partitioning scheme • When is Partitioning faster?

Description: When trying to insert data into a table with hundreds of partitions, performance drops drastically. MySQL partitioning makes data distribution of individual tables (typically we recommend partition for large & complex I/O table for performance, scalability and manageability) across multiple files based on partition strategy / rules.In very simple terms, different portions of table are stored as separate tables in different location to distribute I/O optimally. Section 21.3.4, “Maintenance of Partitions”, discusses table based on MySQL official document.
