Class CouchbaseTableWriteFunction<V>

java.lang.Object

org.apache.samza.table.remote.BaseTableFunction

org.apache.samza.table.remote.couchbase.BaseCouchbaseTableFunction<V>

org.apache.samza.table.remote.couchbase.CouchbaseTableWriteFunction<V>

Type Parameters:

V - Type of values to write to Couchbase

All Implemented Interfaces:

java.io.Serializable, org.apache.samza.operators.functions.ClosableFunction, org.apache.samza.table.remote.TableFunction, org.apache.samza.table.remote.TablePart, org.apache.samza.table.remote.TableWriteFunction<java.lang.String,V>

public class CouchbaseTableWriteFunction<V>
extends BaseCouchbaseTableFunction<V>
implements org.apache.samza.table.remote.TableWriteFunction<java.lang.String,V>

TableWriteFunction implementation for writing to Couchbase. The value type can be either JsonObject or any other Object. If the value type is JsonObject, data will be stored in Couchbase in JSON format, which can be queried with N1QL. Otherwise, a Serde needs to be provided to serialize and deserialize the value object.

Constructor Detail

CouchbaseTableWriteFunction

public CouchbaseTableWriteFunction(java.lang.String bucketName,
                                   java.lang.Class<V> valueClass,
                                   java.lang.String... clusterNodes)

Construct an instance of CouchbaseTableWriteFunction.

Parameters:

bucketName - Name of the couchbase bucket

clusterNodes - Some Hosts of the Couchbase cluster. Recommended to provide more than one nodes so that if the first node could not be connected, other nodes can be tried.

valueClass - Type of values
