= Cassandra Consumer
|
|
|
|
This module provides a Cassandra Consumer that can be reused and composed in other applications.
|
|
Internally it uses the `CassandraMessageHandler` from Spring Integration.
|
|
`CassandraConsumerFunction` is implemented as a `java.util.function.Function`.
|
|
|
|
== Beans for injection
|
|
|
|
The `CassnadraConsumerConfiguration` auto-configuration provides the following beans:
|
|
|
|
`cassandraConsumerFunction`
|
|
|
|
You can use `cassandraConsumerFunction` as a qualifier when injecting.
|
|
|
|
Type for injection: `Function<Object, Mono<? extends WriteResult>>`
|
|
|
|
You have to subscribe to the returned `Mono` to trigger a communication with Cassandra.
|
|
Or use `Consumer<Object> cassandraConsumer` instead which ignores the result and performs just `Mono.block()` before returning.
|
|
|
|
== Configuration Options
|
|
|
|
All configuration properties are prefixed with `cassandra.consumer` and `cassandra.cluster`.
|
|
|
|
For more information on the various options available, please see link:src/main/java/org/springframework/cloud/fn/consumer/cassandra/CassandraConsumerProperties.java[CassandraConsumerProperties].
|
|
See link:src/main/java/org/springframework/cloud/fn/consumer/cassandra/cluster/CassandraClusterProperties.java[this] also.
|
|
|
|
== Tests
|
|
|
|
See this link:src/test/java/org/springframework/cloud/fn/consumer/cassandra[test suite] for the various ways, this consumer is used.
|
|
|
|
== Other usage
|
|
|
|
See this https://github.com/spring-cloud/stream-applications/blob/main/applications/sink/cassandra-sink/README.adoc[README] where this consumer is used to create a Spring Cloud Stream application where it makes a Cassandra sink.
