Class CassandraEmbeddingConfiguration

java.lang.Object

dev.langchain4j.store.embedding.cassandra.CassandraEmbeddingConfiguration

public class CassandraEmbeddingConfiguration
extends Object

Plain old Java Object (POJO) to hold the configuration for the CassandraEmbeddingStore. Wrapping all arguments needed to initialize a store in a single object makes it easier to pass them around. It also makes it easier to add new arguments in the future, without having to change the constructor of the store. This is especially useful when the store is used in a pipeline, where the arguments are passed around multiple times.

table

@NonNull
protected @NonNull String table

Represents the name of the table.

dimension

@NonNull
protected @NonNull Integer dimension
