#### 27.12.8.1 The accounts Table

[]()[]()

 The [`accounts`](performance-schema-accounts-table.html) table contains a row for each account that has connected to the MySQL server. For each account, the table counts the current and total number of connections. The table size is autosized at server startup. To set the table size explicitly, set the [`performance_schema_accounts_size`](performance-schema-system-variables.html#sysvar_performance_schema_accounts_size) system variable at server startup. To disable account statistics, set this variable to 0.

 The [`accounts`](performance-schema-accounts-table.html) table has the following columns. For a description of how the Performance Schema maintains rows in this table, including the effect of [`TRUNCATE TABLE`](truncate-table.html), see [Section 27.12.8, “Performance Schema Connection Tables”](performance-schema-connection-tables.html).

* `USER`

   The client user name for the connection. This is `NULL` for an internal thread, or for a user session that failed to authenticate.

* `HOST`

   The host from which the client connected. This is `NULL` for an internal thread, or for a user session that failed to authenticate.

* `CURRENT_CONNECTIONS`

   The current number of connections for the account.

* `TOTAL_CONNECTIONS`

   The total number of connections for the account.

 The [`accounts`](performance-schema-accounts-table.html) table has these indexes:

* Primary key on (`USER`, `HOST`)
