Debezium MongoDB Connector
Since Camel 3.0
Only consumer is supported
The Debezium MongoDB component is wrapper around Debezium using Debezium Embedded, which enables Change Data Capture from MongoDB database using Debezium without the need for Kafka or Kafka Connect.
Note: The Debezium MongoDB connector uses MongoDB’s oplog to capture the changes, so the connector works only with MongoDB replica sets or with sharded clusters where each shard is a separate replica set, therefore you will need to have your MongoDB instance running either in replica set mode or sharded clusters mode.
Note on handling failures: Per Debezium Embedded Engine documentation, the engines is actively recording source offsets and periodically flushes these offsets to a persistent storage, so when the application is restarted or crashed, the engine will resume from the last recorded offset. Thus, at normal operation, your downstream routes will receive each event exactly once, however in case of an application crash (not having a graceful shutdown), the application will resume from the last recorded offset, which may result in receiving duplicate events immediately after the restart. Therefore, your downstream routes should be tolerant enough of such case and deduplicate events if needed.
Note: The Debezium Mongodb component is currently not supported in OSGi
Maven users will need to add the following dependency to their pom.xml
for this component.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-debezium-mongodb</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>Options
The Debezium MongoDB Connector component supports 58 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
additionalProperties (common) |
Additional properties for debezium components in case they can’t be set directly on the camel configurations (e.g: setting Kafka Connect properties needed by Debezium engine, for example setting KafkaOffsetBackingStore), the properties have to be prefixed with additionalProperties.. E.g: additionalProperties.transactional.id=12345&additionalProperties.schema.registry.url=\http://localhost:8811/avro |

Message headers
Consumer headers
The following headers are available when consuming change events from Debezium.
| Header constant | Header value | Type | Description |
|---|---|---|---|
|
|
|
The identifier of the connector, normally is this format "{server-name}.{database-name}.{table-name}". |
|
|
|
The key of the event, normally is the table Primary Key. |
|
|
|
The metadata about the source event, for example |
|
|
|
If presents, the type of event operation. Values for the connector are |
|
|
|
If presents, the time (using the system clock in the JVM) at which the connector processed the event. |
Note: Debezium Mongodb uses MongoDB’s oplog to populate the CDC events, the update events in MongoDB’s oplog don’t have the before or after states of the changed document, so there’s no way for the Debezium connector to provide this information, therefore header key CamelDebeziumBefore is not available in this component.
Message body
The message body if is not null (in case of tombstones), it contains the state of the row after the event occurred as String JSON format and you can unmarchal using Camel JSON Data Format.
Samples
Consuming events
Here is a very simple route that you can use in order to listen to Debezium events from MongoDB connector.
from("debezium-mongodb:dbz-test-1?offsetStorageFileName=/usr/offset-file-1.dat&mongodbHosts=rs0/localhost:27017&mongodbUser=debezium&mongodbPassword=dbz&mongodbName=dbserver1&databaseHistoryFileName=/usr/history-file-1.dat")
.log("Event received from Debezium : ${body}")
.log(" with this identifier ${headers.CamelDebeziumIdentifier}")
.log(" with these source metadata ${headers.CamelDebeziumSourceMetadata}")
.log(" the event occured upon this operation '${headers.CamelDebeziumSourceOperation}'")
.log(" on this database '${headers.CamelDebeziumSourceMetadata[db]}' and this table '${headers.CamelDebeziumSourceMetadata[table]}'")
.log(" with the key ${headers.CamelDebeziumKey}")
.choice()
.when(header(DebeziumConstants.HEADER_OPERATION).in("c", "u", "r"))
.unmarshal().json()
.log("Event received from Debezium : ${body}")
.end()
.end();By default, the component will emit the events in the body String JSON format in case of u, c or r operations, this can be easily converted to JSON using Camel JSON Data Format e.g: .unmarshal().json() like the above example. In case of operation d, the body will be null.
Important Note: This component is a thin wrapper around Debezium Engine as mentioned, therefore before using this component in production, you need to understand how Debezium works and how configurations can reflect the expected behavior, especially in regards to handling failures.
Spring Boot Auto-Configuration
When using debezium-mongodb with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-debezium-mongodb-starter</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>The component supports 59 options, which are listed below.
