JDBC Message Store¶
Introduction¶
Used for storing and retrieving messages more efficiently in comparison with other message stores. This is a variation of the already existing synapse message store implementation and is designed in a manner similar to the same message store. The JDBC message store uses a JDBC connector to connect to external relational databases.
The advantages of using a JDBC message store instead of any other message store are as follows:
- Easy to connect: You only need to have a JDBC connector to connect to an external relational database.
- Quick transactions: JDBC message stores are capable of handling a large number of transactions per second.
- Ability to work with a high capacity for a long period of time: Since JDBC stores use databases as the medium to store data, it can store a large volume of data and is capable of handling data for a longer period of time.
Properties¶
Listed below are the properties used for creating a JDBC Message Store.
Required Properties¶
The following properties are required when creating a JDBC Message Store.
Property | Description |
---|---|
Name | The name of the message store. |
Database Table | The name of the database table. |
Driver | The class name of the database driver. |
URL | The JDBC URL of the database that the data will be written to. |
User | The user name used to connect to the database. |
Password | The password used to connect to the database. |
Connection Pool Properties¶
The syntax of the JDBC message store can be different depending on whether you connect to the database using a connection pool, or using a datasource. Given below are the connection pool properties:
Property | Description |
---|---|
store.jdbc.driver | The class name of the database driver. |
store.jdbc.connection.url | The database URL. |
store.jdbc.username | The user name to access the database. |
store.jdbc.password | The password to access the database. |
store.jdbc.table | Table name of the database. |
External Datasource Properties¶
The syntax of the JDBC message store can be different depending on whether you connect to the database using a connection pool, or using a datasource. Given below are the external datasource properties:
Property | Description |
---|---|
store.jdbc.dsName | The name of the datasource to be looked up. |
store.jdbc.table | The table name of the database. |
Internal Datasource Properties¶
To make sure that the datasource appears in the Datasource Name list, you need to expose it as a JNDI datasource.
Property | Description |
---|---|
Name | The name for the message store. |
Database Table | The name of the database table. |
Datasource Name | The class name of the datasource. |
