Innodb_buffer_pool_size show

InnoDB Standard Monitor output , which can be accessed using SHOW ENGINE INNODB STATUS , provides metrics regarding operation of the buffer pool. A background thread performs the resizing operation. In a typical server, the buffer pool starts small, but quickly grows to that max size and stays there.

Note: If that is bigger than RAM (or even close), then that leads to swapping, which is terrible for performance. What to set innodb_buffer_pool and why. To enable multiple buffer pool instances, set the innodb_buffer_pool_instances configuration option to a value greater than (the default) up to (the maximum). If innodb _ buffer _ pool _ size is greater than 1. GB was chosen as the boundary at which there is significant risk for 32-bit Windows to be unable to allocate the contiguous address space needed for a single buffer pool.

Plot of InnoDB Buffer Pool Size for Various RAM Sizes. Word of Caution for InnoDB Buffer Pool Size Calculations. The sum of data, misc and free pages is equivalent to total pages.

And the number of total pages multiplied by Innodb _page_ size corresponds to your innodb _ buffer _ pool _ size. This new feature also introduced a new variable — innodb_buffer_pool_chunk_size — which defines the chunk size by which the buffer pool is enlarged or reduced.

The size of the buffer that is used for plain index scans, range index scans, and joins that do not use indexes and thus perform full table scans. Normally, the best way to get fast joins is to add indexes.

I recommend adding indexes or slightly increasing join_buffer_size (but in this case a full table scan will be performed). On Linux, there are thresholds of 256KB and 2MB where larger values may significantly slow down memory allocation (). Unfortunately, I do not have any experience with editing the my.

A materialized view log is located in the master database in the same schema as the master table. A master table can have only one materialized view log defined on it.

Use the ALTER MATERIALIZED VIEW LOG statement to alter the storage characteristics or type of an existing materialized view log. You cannot create a materialized view log for a table in the schema of the user SYS. Specify the schema containing the materialized view log and its master table.

Using materialized views against remote tables is the simplest way to achieve replication of data between sites. To fast refresh a materialized join view , you must create a materialized view log for each of the tables referenced by the materialized views. This is called fast refreshing.

Before a materialized view can perform a fast refresh however it needs a mechanism to capture any changes made to its base table. Use the WITH clause to indicate whether the materialized view log should record the primary key, rowi object I or a combination of these row identifiers when rows in the master are changed.
