 Common components that interact with the TiDB database in Java applications include:
 
 - Network protocol: A client interacts with a TiDB server via the standard [MySQL protocol](https://dev.mysql.com/doc/dev/mysql-server/latest/PAGE_PROTOCOL.html).
-- JDBC API and JDBC drivers: Java applications usually use the standard [JDBC (Java Database Connectivity)](https://docs.oracle.com/javase/8/docs/technotes/guides/jdbc/) API to access a database. To connect to TiDB, you can use a JDBC driver that implements the MySQL protocol via the JDBC API. Such common JDBC drivers for MySQL include [MySQL Connector/J](https://github.com/mysql/mysql-connector-j) and [MariaDB Connector/J](https://mariadb.com/kb/en/library/about-mariadb-connector-j/#about-mariadb-connectorj).

 - Database connection pool: To reduce the overhead of creating a connection each time it is requested, applications usually use a connection pool to cache and reuse connections. JDBC [DataSource](https://docs.oracle.com/javase/8/docs/api/javax/sql/DataSource.html) defines a connection pool API. You can choose from different open-source connection pool implementations as needed.
 - Data access framework: Applications usually use a data access framework such as [MyBatis](https://mybatis.org/mybatis-3/index.html) and [Hibernate](https://hibernate.org/) to further simplify and manage the database access operations.
 - Application implementation: The application logic controls when to send what commands to the database. Some applications use [Spring Transaction](https://docs.spring.io/spring/docs/4.2.x/spring-framework-reference/html/transaction.html) aspects to manage transactions' start and commit logics.

 ### MySQL JDBC parameters
 
-JDBC usually provides implementation-related configurations in the form of JDBC URL parameters. This section introduces [MySQL Connector/J's parameter configurations](https://dev.mysql.com/doc/connector-j/en/connector-j-reference-configuration-properties.html) (If you use MariaDB, see [MariaDB's parameter configurations](https://mariadb.com/kb/en/library/about-mariadb-connector-j/#optional-url-parameters)). Because this document cannot cover all configuration items, it mainly focuses on several parameters that might affect performance.

Refer to [MySQL Binary Log](https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_replication.html) and [MariaDB Binary Log](https://mariadb.com/kb/en/library/binary-log/) for details.

 ### Binlog event
 
-Binlog events are information about data modification made to a MySQL or MariaDB server instance. These binlog events are stored in the binlog files. Refer to [MySQL Binlog Event](https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_replication_binlog_event.html) and [MariaDB Binlog Event](https://mariadb.com/kb/en/library/1-binlog-events/) for details.

 ### Binlog event filter
 
 [Binlog event filter](/dm/dm-binlog-event-filter.md) is a more fine-grained filtering feature than the block and allow lists filtering rule. Refer to [binlog event filter](/dm/dm-binlog-event-filter.md) for details.
 
 ### Binlog position
 
-The binlog position is the offset information of a binlog event in a binlog file. Refer to [MySQL `SHOW BINLOG EVENTS`](https://dev.mysql.com/doc/refman/8.0/en/show-binlog-events.html) and [MariaDB `SHOW BINLOG EVENTS`](https://mariadb.com/kb/en/library/show-binlog-events/) for details.

 ### Binlog replication processing unit/sync unit
 
 Binlog replication processing unit is the processing unit used in DM-worker to read upstream binlogs or local relay logs, and to migrate these logs to the downstream. Each subtask corresponds to a binlog replication processing unit. In the current documentation, the binlog replication processing unit is also referred to as the sync processing unit.
 
 ### Block & allow table list
 
-Block & allow table list is the feature that filters or only migrates all operations of some databases or some tables. Refer to [block & allow table lists](/dm/dm-block-allow-table-lists.md) for details. This feature is similar to [MySQL Replication Filtering](https://dev.mysql.com/doc/refman/8.0/en/replication-rules.html) and [MariaDB Replication Filters](https://mariadb.com/kb/en/replication-filters/).
