innodb_buffer_pool_instances. Also make sure that innodb_buffer_pool_size is for performance reasons set to x4 of log file size. Change the innodb_log_file_size value in MySQL/MariaDB with assistance from our in-house experts. You should set the combined size # of log files to about 25%-100% of your buffer pool size to avoid # unneeded buffer pool flush activity on log file overwrite. Overview. Default options are read from the following files in the given order . But for most systems, 48M is plenty big. On log checkpoint, some file name information needs to be appended to the log. MariaDB, version 10.4; Setup. At Bobcares, we offer solutions for every query, big and small, as a part of our Server Management Service. The combined size of log files (innodb_log_file_size * innodb_log_files_in_group) cannot exceed a maximum value that is slightly less than 512GB. innodb_io_capacity = 800 -> Why are you setting this? Lower your innodb_log_buffer_size to 32M. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M # # Remove leading # to revert to previous value for default_authentication_plugin, # this will increase compatibility with older clients. Ratio InnoDB log file size / InnoDB Buffer pool size (75 %): 96.0M * 1/128.0M should be equal to 25% [--] Number of InnoDB Buffer Pool Chunk : 1 for 1 Buffer Pool Instance(s) [OK] Innodb_buffer_pool_size aligned with Innodb_buffer_pool_chunk_size & Innodb_buffer_pool_instances [OK] InnoDB Read buffer efficiency: 99.98% (499634018 hits .

The new buffer pool size must be a multiple of innodb_buffer_pool_chunk_size * innodb_buffer_pool_instances (note that innodb_buffer_pool_instances is ignored from MariaDB 10.5, and removed in MariaDB 10.6, as the buffer pool is no longer split into multiple instances). To change the log file size, configure innodb_log_file_size. A specific reference to this ^^ is here: InnoDB System Variables but the chosen value of 2 is commented out (#) anyway @UHolthausen so the default value of 1 should still be being applied, without causing any issues, as noted ^^ by @john0001 The innodb_file_size value of 128M is also commented out (#) too. .
