-
-*Since Camel 3.0*
-
-The Debezium component is wrapper around https://debezium.io/[Debezium] using
https://debezium.io/documentation/reference/0.9/operations/embedded.html[Debezium
Embedded], which enables Change Data Capture from various databases using
Debezium without the need for Kafka or Kafka Connect.
-
-*Note on handling failures:* Per
https://debezium.io/documentation/reference/0.9/operations/embedded.html#_handling_failures[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.
-
-Maven users will need to add the following dependency to their `pom.xml`
-for this component.

option may expose tables or fields explicitly blacklisted or masked by
including the original SQL statement in the change event. For this reason the
default value is 'false'. | false | [...]
-| *includeSchemaChanges* (mysql) | Whether the connector should publish
changes in the database schema to a Kafka topic with the same name as the
database server ID. Each schema change will be recorded using a key that
contains the database name and whose value includes the DDL statement(s).The
default is 'true'. This is independent of how the connector internally records
database history. | true | boolean

the global read lock while it is performing a snapshot. The default is
'minimal', which means the connector holds the global read lock (and thus
prevents any updates) for just the initial portion of the snapshot while the
database schemas and other metadata are being read. The remaining work in a
snapshot involves selecting all rows from each table, and this can be done
using the snapshot process' REPEATABLE REA [...]
-| *snapshotMode* (mysql) | The criteria for running a snapshot upon startup of
the connector. Options include: 'when_needed' to specify that the connector run
a snapshot upon startup whenever it deems it necessary; 'initial' (the default)

precision;'adaptive' (deprecated) bases the precision of time, date, and
timestamp values on the database column's precision; 'connect' always
represents time, date, and timestamp values using Kafka Connect's built-in
representations for Time, Date, and Timestamp [...]
-| *tombstonesOnDelete* (mysql) | 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)

-== Message headers
-
-=== Consumer headers
-
-The following headers are available when consuming change events from Debezium.
-[width="100%",cols="2m,2m,1m,5",options="header"]
-|===
-| 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 MySQL connector.
-[source,java]
-----
-from("debezium:mysql?name=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
https://kafka.apache.org/22/javadoc/org/apache/kafka/connect/data/Struct.html[`Struct`]
data type, the reasoning behind this, is to perceive the schema information in
case is needed.
-However, the component as well contains a
xref:manual::type-converter.adoc[Type Converter] that converts
-from default output type of
https://kafka.apache.org/22/javadoc/org/apache/kafka/connect/data/Struct.html[`Struct`]
to `Map` in order to leverage Camel's rich xref:manual::data-format.adoc[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
https://kafka.apache.org/22/javadoc/org/apache/kafka/connect/data/Schema.html[`Schema`]
type from `Struct` like this:
-[source,java]
-----
-from("debezium:[connectorType]?[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
https://debezium.io/documentation/reference/0.9/operations/embedded.html#_handling_failures[handling
failures].

+
+*Since Camel 3.0*
+
+The Debezium MySQL component is wrapper around https://debezium.io/[Debezium]
using
https://debezium.io/documentation/reference/0.9/operations/embedded.html[Debezium
Embedded], which enables Change Data Capture from MySQL database using
Debezium without the need for Kafka or Kafka Connect.
+
+*Note on handling failures:* Per
https://debezium.io/documentation/reference/0.9/operations/embedded.html#_handling_failures[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.
+
+Maven users will need to add the following dependency to their `pom.xml`
+for this component.

changes in the database schema to a Kafka topic with the same name as the
database server ID. Each schema change will be recorded using a key that
contains the database name and whose value includes the DDL statement(s).The

the global read lock while it is performing a snapshot. The default is
'minimal', which means the connector holds the global read lock (and thus
prevents any updates) for just the initial portion of the snapshot while the
database schemas and other metadata are being read. The remaining work in a
snapshot involves selecting all rows from each table, and this can be done
using the snapshot process' REPEATABLE REA [...]
+| *snapshotMode* (mysql) | The criteria for running a snapshot upon startup of
the connector. Options include: 'when_needed' to specify that the connector run
a snapshot upon startup whenever it deems it necessary; 'initial' (the default)

precision;'adaptive' (deprecated) bases the precision of time, date, and
timestamp values on the database column's precision; 'connect' always
represents time, date, and timestamp values using Kafka Connect's built-in
representations for Time, Date, and Timestamp [...]
+| *tombstonesOnDelete* (mysql) | 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)

+== Message headers
+
+=== Consumer headers
+
+The following headers are available when consuming change events from Debezium.
+[width="100%",cols="2m,2m,1m,5",options="header"]
+|===
+| 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 MySQL connector.
+[source,java]
+----
+from("debezium-mysql: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
https://kafka.apache.org/22/javadoc/org/apache/kafka/connect/data/Struct.html[`Struct`]
data type, the reasoning behind this, is to perceive the schema information in
case is needed.
+However, the component as well contains a
xref:manual::type-converter.adoc[Type Converter] that converts
+from default output type of
https://kafka.apache.org/22/javadoc/org/apache/kafka/connect/data/Struct.html[`Struct`]
to `Map` in order to leverage Camel's rich xref:manual::data-format.adoc[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
https://kafka.apache.org/22/javadoc/org/apache/kafka/connect/data/Schema.html[`Schema`]
type from `Struct` like this:
+[source,java]
+----
+from("debezium-mysql:[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
https://debezium.io/documentation/reference/0.9/operations/embedded.html#_handling_failures[handling
failures].
