Camel Spring Boot Starter for debezium-sqlserver

Spring Boot Auto-Configuration

When using debezium-sqlserver 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-sqlserver-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 56 options, which are listed below.

Name Description Default Type

camel.component.debezium-sqlserver.additional-properties

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

Map

camel.component.debezium-sqlserver.basic-property-binding

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

false

Boolean

camel.component.debezium-sqlserver.skipped-operations

Integer

camel.component.debezium-sqlserver.snapshot-isolation-mode

Controls which transaction isolation level is used and how long the connector locks the monitored tables. The default is 'repeatable_read', which means that repeatable read isolation level is used. In addition, exclusive locks are taken only during schema snapshot. Using a value of 'exclusive' ensures that the connector holds the exclusive lock (and thus prevents any reads and updates) for all monitored tables during the entire snapshot duration. When 'snapshot' is specified, connector runs the initial snapshot in SNAPSHOT isolation level, which guarantees snapshot consistency. In addition, neither table nor row-level locks are held. When 'read_committed' is specified, connector runs the initial snapshot in READ COMMITTED isolation level. No long-running locks are taken, so that initial snapshot does not prevent other transactions from updating table rows. Snapshot consistency is not guaranteed.In 'read_uncommitted' mode neither table nor row-level locks are acquired, but connector does not guarantee snapshot consistency.

repeatable_read

String

camel.component.debezium-sqlserver.snapshot-lock-timeout-ms

String

camel.component.debezium-sqlserver.snapshot-mode

The criteria for running a snapshot upon startup of the connector. Options include: 'initial' (the default) to specify the connector should run a snapshot only when no offsets are available for the logical server name; 'schema_only' to specify the connector should run a snapshot of the schema when no offsets are available for the logical server name.

initial

String

camel.component.debezium-sqlserver.snapshot-select-statement-overrides

This property contains a comma-separated list of fully-qualified tables (DB_NAME.TABLE_NAME) or (SCHEMA_NAME.TABLE_NAME), depending on thespecific connectors . Select statements for the individual tables are specified in further configuration properties, one for each table, identified by the id 'snapshot.select.statement.overrides.DB_NAME.TABLE_NAME' or 'snapshot.select.statement.overrides.SCHEMA_NAME.TABLE_NAME', respectively. The value of those properties is the select statement to use when retrieving data from the specific table during snapshotting. A possible use case for large append-only tables is setting a specific point where to start (resume) snapshotting, in case a previous snapshotting was interrupted.

adaptive

String

camel.component.debezium-sqlserver.tombstones-on-delete

Whether delete operations should be represented by a delete event and a subsquenttombstone event (true) or only by a delete event (false). Emitting the tombstone event (the default behavior) allows Kafka to completely delete all events pertaining to the given key once the source record got deleted.

false

Boolean
