a9s MySQL Resources Considerations
This document describes concerns and limitations to be considered when allocating resources for your a9s MySQL plans.
The relevant buffer configuration configured by a9s MySQL is
innodb_buffer_pool_size, which by
total_memory - 1GB reserved. a9s MySQL reserves
1GB for side processes,
and it is configured to use
50% of the remaining memory.
The remaining memory is shared with other small buffers, side processes, and the OS. It is
important to notice that the number of open connections influences on the usage of the remaining
max_connections is configured as
1500, but to instances, this might be too
much, and the number of open connection will directly affect the performance of your node.
