Hello,
Problem:
There is an issue that RAM usage is too high for mysqld, it uses around 86% of memory. Following are the system information,
RAM : 48168.6M
Buffer pool config: innodb_buffer_pool_size=38534M
So from the above configuration that 80% of the RAM is allocation to the buffer pool to cache the data from the physical DB. We cannot change the innodb_buffer_pool_size as we need to support high availability and throughput time.
Query:
1. Is there a way to optimize the RAM usage of mysqld?
2. Is it possible that RAM get fragmented with huge transaction with update/insert/delete as it always reflects in both RAM and hard disk?
3. Can you please provide the De-fragmentation steps to perform it on the RAM to optimize the memory usage ?
For any other information needed please reply.
Thanks in advance.
