Debezium SQL Server Connector Component

Since Camel 3.0

Only consumer is supported

The Debezium SQL Server component is wrapper around Debezium using Debezium Embedded, which enables Change Data Capture from SQL Server database using Debezium without the need for Kafka or Kafka Connect.

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 SQL Server 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-sqlserver</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

Options

The Debezium SQL Server Connector component supports 4 options, which are listed below.

Name Description Default Type

configuration (consumer)

Allow pre-configured Configurations to be set.

SqlServerConnectorEmbeddedDebeziumConfiguration

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

The Debezium SQL Server Connector endpoint is configured using URI syntax:

Message headers

Consumer headers

The following headers are available when consuming change events from Debezium.

Header constant Header value Type Description

DebeziumConstants.HEADER_IDENTIFIER

"CamelDebeziumIdentifier"

String

The identifier of the connector, normally is this format "{server-name}.{database-name}.{table-name}".

DebeziumConstants.HEADER_KEY

"CamelDebeziumKey"

Struct

The key of the event, normally is the table Primary Key.

DebeziumConstants.HEADER_SOURCE_METADATA

"CamelDebeziumSourceMetadata"

Map

The metadata about the source event, for example table name, database name, log position, etc, please refer to the Debezium documentation for more info.

DebeziumConstants.HEADER_OPERATION

"CamelDebeziumOperation"

String

If presents, the type of event operation. Values for the connector are c for create (or insert), u for update, d for delete or r in case of a snapshot event.

DebeziumConstants.HEADER_TIMESTAMP

"CamelDebeziumTimestamp"

Long

If presents, the time (using the system clock in the JVM) at which the connector processed the event.

DebeziumConstants.HEADER_BEFORE

"CamelDebeziumBefore"

Struct

If presents, contains the state of the row before the event occurred.

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 Struct format or Map format if you use the included Type Converter from Struct to Map (please look below for more explanation).

Samples

Consuming events

Here is a very simple route that you can use in order to listen to Debezium events from SQL Server connector.

from("debezium-sqlserver:dbz-test-1?offsetStorageFileName=/usr/offset-file-1.dat&databaseHostName=localhost&databaseUser=debezium&databasePassword=dbz&databaseServerName=my-app-connector&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}")
    .log("    the previous value is ${headers.CamelDebeziumBefore}")

By default, the component will emit the events in the body and CamelDebeziumBefore header as Struct data type, the reasoning behind this, is to perceive the schema information in case is needed. However, the component as well contains a Type Converter that converts from default output type of Struct to Map in order to leverage Camel’s rich Data Format types which many of them work out of box with Map data type. To use it, you can either add Map.class type when you access the message e.g: exchange.getIn().getBody(Map.class), or you can convert the body always to Map from the route builder by adding .convertBodyTo(Map.class) to your Camel Route DSL after from statement.

We mentioned above about the schema, which can be used in case you need to perform advance data transformation and the schema is needed for that. If you choose not to convert your body to Map, you can obtain the schema information as Schema type from Struct like this:

from("debezium-sqlserver:[name]?[options]])
    .process(exchange -> {
        final Struct bodyValue = exchange.getIn().getBody(Struct.class);
        final Schema schemaValue = bodyValue.schema();

        log.info("Body value is :" + bodyValue);
        log.info("With Schema : " + schemaValue);
        log.info("And fields of :" + schemaValue.fields());
        log.info("Field name has `" + schemaValue.field("name").schema() + "` type");
    });

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.
