3 varchar(10) utf8_general_ci FOREGROUND or BACKGROUND, depending on the thread type. User connection threads are FOREGROUND, internal server threads are BACKGROUND.
4 bigint(20) UNSIGNED NULL The PROCESSLIST.ID value for threads displayed in the INFORMATION_SCHEMA.PROCESSLIST table, or 0 for background threads. Also corresponds with the CONNECTION_ID() return value for the thread.
5 varchar(128) utf8_general_ci NULL Foreground thread user, or NULL for a background thread.
6 varchar(60) utf8_general_ci NULL Foreground thread host, or NULL for a background thread.
7 varchar(64) utf8_general_ci NULL Thread's default database, or NULL if none exists.
8 varchar(16) utf8_general_ci NULL Type of command executed by the thread. These correspond to the the COM_xxx client/server protocol commands, and the Com_xxx status variables. See Thread Command Values.
9 bigint(20) NULL Time in seconds the thread has been in its current state.
10 varchar(64) utf8_general_ci NULL Action, event or state indicating what the thread is doing.
11 longtext utf8_general_ci NULL Statement being executed by the thread, or NULL if a statement is not being executed. If a statement results in calling other statements, such as for a stored procedure, the innermost statement from the stored procedure is shown here.
12 bigint(20) UNSIGNED NULL THREAD_ID of the parent thread, if any. Subthreads can for example be spawned as a result of INSERT DELAYED statements.
13 varchar(64) utf8_general_ci NULL Unused.
14 enum('YES', 'NO') utf8_general_ci YES or NO for Whether the thread is instrumented or not. For foreground threads, the initial value is determined by whether there's a user/host match in the setup_actors table. Subthreads are again matched, while for background threads, this will be set to YES by default. To monitor events that the thread executes, INSTRUMENTED must be YES and the thread_instrumentation consumer in the setup_consumers table must also be YES.
