| #### Does TiDB support XA？ | |||

|||
| No. TiDB JDBC drive is MySQL JDBC (Connector/J). When using Atomikos, set the data source to `type="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource"`. TiDB does not support the connection with MySQL JDBC XADataSource. MySQL JDBC XADataSource only works for MySQL (for example, using DML to modify the `redo` log). | |||

"TiDB JDBC drive" -> "The JDBC drive of TiDB". I think it sounds better this way.

||
| After you configure the two data sources of Atomikos, set the JDBC drives to XA. When Atomikos operates TM and RM (DB), Atomikos sends the command about XA to JDBC layer. Taking MySQL for an example, when XA is enabled in the JDBC layer, JDBC will send a series of XA logic operations to InnoDB, including using DML to change the `redo` log. This is the operation of the two-phase commit. The current TiDB version does not support the upper application layer JTA/XA and does not parse operations about XA sent by Atomikos. |

- sends the command about XA to JDBC layer -> sends the command including XA to the JDBC layer
- operations about XA -> XA operations

| The display content of TiDB `show processlist` is almost the same as that of MySQL `show processlist`. TiDB `show processlist` does not display the system process ID. The ID that it displays is the current session ID. The differences between TiDB `show processlist` and MySQL `show processlist` are as follows: | ||
|
|
||
| - As TiDB is a distributed database, the `tidb-server` instance is a stateless engine for parsing and executing the SQL statements (for details, see [TiDB architecture](overview.md#tidb-architecture)). `show processlist` displays the session list executed in the `tidb-server` instance which the user uses the MySQL client to log into, not the list of all the sessions running in the cluster. But MySQL is a standalone database and its `show processlist` displays all the SQL statements executed in MySQL. |

which the user uses the MySQL client to log into -> that the user logs in to from the MySQL client

| `cop task` is the computing task which is pushed down to the KV end for execution distributedly; `root task` is the computing task executed for single point of execution on TiDB end. | ||
|
|
||
| Generally the input data of `root task` comes from `cop task`; when `root task` processes data, `cop task` of TiKV can processes data at the same time and waits for the pull of `root task` of TiDB. Therefore, `cop` tasks can be considered as executed concurrently; but their data is of upstream and downstream relation. During the execution process, they are executed concurrently during some time. For example, the first `cop task` is processing the data in [100, 200] and the second `cop task` is processing the data in [1, 100]. For details, see [Understanding the TiDB Query Plan](sql/understanding-the-query-execution-plan.md). |

|
|
|||
| In TiDB 2.0, Region health is monitored in the PD metric monitor page, in which the `Region Health` monitor item shows the statistics of all the Region replica status. `miss` means shortage of replicas and `extra` means the extra replica exists. In addition, `Region Health` also shows the isolation level by `label`. `level-1` means the Region replicas are isolated physically in the first `label` level. All the Regions are in `level-0` when `location label` is not configured. | |||
