I'd avoid slow innodb engine for "temporary" frequently changing tables like
location. Use MyISAM engine instead for the table.

Also, what value do you have for MySQL parameter
innodb_buffer_pool_size and
how large is your MySQL data directory at peak?

Thank you so much for your response. Well if putting the table into memory
is not a good option what is the best way to handle this situation?

that as being a major issue for transient data such as that stored in the
Kamailio DB.
I’m not entirely convinced that changing it to a memory table will help as
you are presumably doing MySQL replication between your two Kamailio nodes.
Memory tables don’t replicate well.

On average I have about 2000 registrations per second and this configuration
does not work with this rate. Maximum number of registrations that we can
handle with db_mode 3 is 1000 per second.

Subject: [SR-Users] Location Table In db_mode 3
I have multiple Kamailio servers in an Active/Active scenario (the database
is a MySQL server) using db_mode 3. But when the number of clients goes up
writes on the location table become too much and it causes database
problems. I even put my location table on a separate SSD disk on the server
to separate it's IO but still at times I have problems. How can I move
location table into memory? Is this a good solution? What other options do
I have?
