In this chapter, we learned how to use partitioning to optimize very big tables.

We learned which partitioning types are supported by MariaDB and how to write a good partitioning expression. We examined a sample table and learned how we can benefit from different partitioning strategies. We discussed subpartitioning. We learned the SQL statements that can be used to maintain partitions. Finally, we discussed how the optimizer excludes the irrelevant partitions from a statement execution, and how the use can force the exclusive use of some partitions.

In the next chapter, we will discuss how to distribute data across multiple servers.
