MongoDB Data Sources

MongoDB data sources use a Teiid specific JCA connector that is deployed into WildFly 17.0.0 during installation. There are many ways to create a MongoDB data source, using CLI, admin-console, etc. The example shown below uses the CLI tool, as this works in both Standalone and Domain modes.

Execute the following command using the CLI once you connected to the Server. Make sure you provide the correct URL and user credentials. Add any additional properties required by the connector by duplicating the "connection-definitions" command below. Edit the JNDI name to match the JNDI name you used in VDB.

batch
/subsystem=resource-adapters/resource-adapter=mongodb/connection-definitions=mongodbDS:add(jndi-name="java:/mongoDS", class-name=org.teiid.resource.adapter.mongodb.MongoDBManagedConnectionFactory, enabled=true, use-java-context=true)
/subsystem=resource-adapters/resource-adapter=mongodb/connection-definitions=mongodbDS/config-properties=RemoteServerList:add(value="{host}:27017")
/subsystem=resource-adapters/resource-adapter=mongodb/connection-definitions=mongodbDS/config-properties=Database:add(value="{db-name}")
/subsystem=resource-adapters/resource-adapter=mongodb:activate
runbatch

All the properties that are defined on the RAR file are

Property Name Description Required Default

RemoteServerList

A comma separated list of server locations. Each location can contain an optional port, of the format host:port. The property may also contain a full standard (mongodb://) or seedlist (mongodb+srv://) connection string.

true

Username

Connection User’s Name

false

none

Password

Connection User’s password

false

none

Database

MongoDB database name

true

none

SecurityType

MongoDB Type of Authentication to be used. Allowed values are "None","SCRAM_SHA_1","MONGODB_CR", "Kerberos","X509". If you are using MongoDB version lessthan 3.0, MongoDB by default uses "MONGODB_CR", thus this value need to be set accordingly or set to None.

false

SCRAM_SHA_1

AuthDatabase

MongoDB Database Name for user authentication in case when SecurityType 'MONGODB-CR' is used. This is an optional value.

false

none

Ssl

Use SSL Connections

false

none

To find out all the properties that are supported by this MongoDB Connector execute the following command in the CLI.

/subsystem=teiid:read-rar-description(rar-name=mongodb)
Tip
Developer’s Tip - If WildFly 17.0.0 is running in standalone mode, you can also manually edit the "<jboss-install>/standalone/configuration/standalone-teiid.xml" file and add the XML configuration defined in "<jboss-install>/docs/teiid/datasources/mongodb" directory under "resource-adapters" subsystem. Shutdown the server before you edit this file, and restart after the modifications are done.

Transaction support

With Teiid 12.1 running against a MongoDB server 4+ in a replica set, you may optionally use LocalTransaction transaction support. Doing so through the CLI requires the creation of a new resource adapter.

batch
/subsystem=resource-adapters/resource-adapter=mongodbLocal:add(transaction-support=LocalTransaction, module=org.jboss.teiid.resource-adapter.mongodb:main
/subsystem=resource-adapters/resource-adapter=mongodbLocal/connection-definitions=mongodbLocal:add(jndi-name="java:/mongoDS", class-name=org.teiid.resource.adapter.mongodb.MongoDBManagedConnectionFactory, enabled=true, use-java-context=true)
