What is Debezium?
Debezium is an open-source distributed platform that provides change data capture (CDC) functionality. It allows you to monitor and capture changes in data stores, such as databases, and stream those changes to other systems in real-time.
Debezium is built on top of Apache Kafka and uses Kafka Connect to monitor and capture changes. It provides connectors for various data stores, including MySQL, PostgreSQL, Oracle, MongoDB, and more.
Using Debezium, you can easily set up CDC for your data stores and stream the changes to other systems for further processing or analysis. This can be useful for a variety of use cases, such as synchronizing data between systems, data replication, and event-driven architectures.
SpringBoot Debezium MySQL Example
Here is an example of how you could use Debezium with Spring Boot to monitor and capture changes in a database:
First, you will need to add the Debezium dependencies to your project’s pom.xml file:\
io.debezium debezium-core 1.4.0.Final io.debezium debezium-connector-mysql 1.4.0.Final
Next, you will need to configure the Debezium connector in your application’s application.properties file:
# Debezium MySQL connector configuration spring.datasource.url=jdbc:mysql://localhost:3306/test spring.datasource.username=user spring.datasource.password=password # Debezium configuration debezium.name=my-connector debezium.connector.class=io.debezium.connector.mysql.MySqlConnector debezium.offset.storage=org.apache.kafka.connect.storage.FileOffsetBackingStore debezium.offset.storage.file.filename=/tmp/debezium/offsets.dat debezium.offset.flush.interval.ms=60000 debezium.config.common.key.converter=org.apache.kafka.connect.json.JsonConverter debezium.config.common.value.converter=org.apache.kafka.connect.json.JsonConverter debezium.config.common.key.converter.schemas.enable=true debezium.config.common.value.converter.schemas.enable=true debezium.config.connector.mysql.server.id=12345 debezium.config.connector.mysql.server.name=my-server debezium.config.connector.mysql.hostname=localhost debezium.config.connector.mysql.port=3306 debezium.config.connector.mysql.user=user debezium.config.connector.mysql.password=password debezium.config.connector.mysql.database.whitelist=test debezium.config.connector.mysql.table.whitelist=test.customers
Then, you can create a DebeziumConfig class to initialize the Debezium connector:
@Configuration public class DebeziumConfig { @Bean public EmbeddedEngine embeddedEngine(@Value("${debezium.name}") String connectorName, @Value("${debezium.config.common.key.converter}") String keyConverter, @Value("${debezium.config.common.value
SpringBoot Debezium PostgreSQL example
Here is an example of how you could use Debezium with Spring Boot to monitor and capture changes in a PostgreSQL database:
First, you will need to add the Debezium dependencies to your project’s pom.xml file:
io.debezium debezium-core 1.4.0.Final io.debezium debezium-connector-postgresql 1.4.0.Final
Next, you will need to configure the Debezium connector in your application’s application.properties file:
# Debezium PostgreSQL connector configuration spring.datasource.url=jdbc:postgresql://localhost:5432/test spring.datasource.username=user spring.datasource.password=password # Debezium configuration debezium.name=my-connector debezium.connector.class=io.debezium.connector.postgresql.PostgresConnector debezium.offset.storage=org.apache.kafka.connect.storage.FileOffsetBackingStore debezium.offset.storage.file.filename=/tmp/debezium/offsets.dat debezium.offset.flush.interval.ms=60000 debezium.config.common.key.converter=org.apache.kafka.connect.json.JsonConverter debezium.config.common.value.converter=org.apache.kafka.connect.json.JsonConverter debezium.config.common.key.converter.schemas.enable=true debezium.config.common.value.converter.schemas.enable=true debezium.config.connector.postgresql.server.name=my-server debezium.config.connector.postgresql.hostname=localhost debezium.config.connector.postgresql.port=5432 debezium.config.connector.postgresql.user=user debezium.config.connector.postgresql.password=password debezium.config.connector.postgresql.database.whitelist=test debezium.config.connector.postgresql.table.whitelist=test.customers
Then, you can create a DebeziumConfig class to initialize the Debezium connector:
@Configuration public class DebeziumConfig { @Bean public EmbeddedEngine embeddedEngine(@Value("${debezium.name}") String connectorName, @Value("${debezium.config.common.key.converter}") String keyConverter, @Value("${debezium.config.common.value.converter}") String value
SpringBoot Debezium AWS RDS Example
Here is an example of how you could use Debezium with Spring Boot to monitor and capture changes in an Amazon RDS database:
First, you will need to add the Debezium dependencies to your project’s pom.xml file:
io.debezium debezium-core 1.4.0.Final io.debezium debezium-connector-mysql 1.4.0.Final
Next, you will need to configure the Debezium connector in your application’s application.properties file:
# Debezium MySQL connector configuration spring.datasource.url=jdbc:mysql://: / spring.datasource.username= spring.datasource.password= # Debezium configuration debezium.name=my-connector debezium.connector.class=io.debezium.connector.mysql.MySqlConnector debezium.offset.storage=org.apache.kafka.connect.storage.FileOffsetBackingStore debezium.offset.storage.file.filename=/tmp/debezium/offsets.dat debezium.offset.flush.interval.ms=60000 debezium.config.common.key.converter=org.apache.kafka.connect.json.JsonConverter debezium.config.common.value.converter=org.apache.kafka.connect.json.JsonConverter debezium.config.common.key.converter.schemas.enable=true debezium.config.common.value.converter.schemas.enable=true debezium.config.connector.mysql.server.id=12345 debezium.config.connector.mysql.server.name=my-server debezium.config.connector.mysql.hostname= debezium.config.connector.mysql.port= debezium.config.connector.mysql.user= debezium.config.connector.mysql.password= debezium.config.connector.mysql.database.whitelist= debezium.config.connector.mysql.table.whitelist= .customers
