= 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.
