Let’s see how the Partition Maintenance is done in MariaDB. At Bobcares, with our Server Management Services, we can handle your server issues.

Partition Maintenance in MariaDB

We can divide one table into multiple smaller tables using this method. The size of the table, however, hardly affects performance. The problems are actually with I/O time and indexes.

With MariaDB 5.6’s, we can use specific SQL statements to complete a variety of partition maintenance jobs. We can use multiple statements for table maintenance.

For running these actions directly on one or more partitions, we can use a number of extensions to ALTER TABLE, as follows:

1. Rebuilding partitions: This has the same effect as deleting all data from a partition and then re-inserting it. Defragmentation objectives may benefit from this.

2. Optimizing partitions: We may use ALTER TABLE… OPTIMIZE PARTITION to recover any unused space and to defragment the partition data file if we’ve removed a lot of rows from a partition. We can also use it if we’ve made a lot of changes to a partitioned table with variable-length rows.

3. Analyzing partitions: The key distributions are read and stored in this manner.

4. Repairing partitions: We use this extension to repair corrupted partitions.

5. Checking partitions: We can check partitions for errors in much the same way that we can use CHECK TABLE with nonpartitioned tables. If we see any error, we can use ALTER TABLE … REPAIR PARTITION to repair the partition.

Using ALTER TABLE… TRUNCATE PARTITION in MariaDB 5.6, we may also reduce partitions. Similar to how TRUNCATE TABLE deletes all rows from a table, this command will delete all rows from one or more partitions. We can use the keyword ALL instead of the list of partition names so that these statements act on all partitions in the table.
