How can Mysql server auto re-index tables
I have a table which has very minimal data. However the index_length is very very huge, because of frequent DML operations on this table.
Ex :
+-----------------------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+---------+
| Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment |
+-----------------------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+---------+
| TABLE_NAME | InnoDB | 10 | Compact | 0 | 0 | 16384 | 0 | 1046790144 | 6291456 | NULL | 2018-01-29 18:29:41 | NULL | NULL | utf8_general_ci | NULL | | |
To manually fix this, we can use OPTIMIZE TABLE command to re-index a table.
How can we configure it on db server side, so that re-index happens automatically based on some configuration or threshold ?

There is no way to auto-reindex.
As you point out, OPTIMIZE TABLE
(or certain variants of ALTER TABLE
) will rebuild the index(es).
Instead, please elaborate on what is going on that led to the situation. Perhaps there is another approach that can avoid the 'problem'.
