Configuration

The connector is configured using the org.infinispan.spark.config.ConnectorConfiguration class, the following methods are provided:

Method Description Default
setServerList(String) List of servers localhost:11222
setCacheName(String) The name of the Infinispan cache to be used in the computations default cache
setAutoCreateCacheFromConfig(String) Creates the cache with the supplied configuration in case it does not exist. The configuration is in XML format and follows the Infinispan Embedded Schema
setAutoCreateCacheFromTemplate(String) Creates the cache with a pre-existent configuration template in case it does not exist. This setting is ignored if setAutoCreateCacheFromConfig() was previously called
setReadBatchSize(Integer) Batch size (number of entries) when reading from the cache 10000
setWriteBatchSize(Integer) Batch size (number of entries) when writing to the cache 500
setPartitions(Integer) Number of partitions created per Infinispan server when processing data 2
addProtoFile(String name, String contents) Register a protobuf file describing one or more entities in the cache Can be omitted if entities are annotated with protobuf encoding information. Protobuf encoding is required to filter the RDD by Query or to use the Dataset API
addMessageMarshaller(Class) Registers a Message Marshaller for an entity in the cache Can be omitted if entities are annotated with protobuf encoding information. Protobuf encoding is required to filter the RDD by Query or to use the Dataset API
addProtoAnnotatedClass(Class) Registers a Class containing protobuf annotations such as @ProtoMessage and @ProtoField Alternative to using addProtoFile and addMessageMarshaller methods, since both will be auto-generated based on the annotations.
setAutoRegisterProto() Will cause automatically registration of protobuf schemas in the server. The schema can either be provided by addProtoFile() or inferred from the annotated classes registered with addProtoAnnotatedClass no automatic registration is done
addHotRodClientProperty(key, value) Used to configured extra Hot Rod client properties when contacting the Infinispan Server
setTargetEntity(Class) Used in conjunction with the Dataset API to specify the Query target If omitted, and in case there is only one class annotated with protobuf configured, it will choose that class
setKeyMarshaller(Class) An implementation of org.infinispan.commons.marshall.Marshaller used to serialize and deserialize the keys org.infinispan.jboss.marshalling.commons.GenericJBossMarshaller
setValueMarshaller(Class) Same as keyMarshaller but for the values same default as above
setKeyMediaType(String) Specify an alternate Media type to be used for keys during cache operations. Infinispan will convert the stored keys to this format when reading data. It is recommended to configure the Media Type of the cache when planning to use this property application/x-jboss-marshalling or application/x-protostream when using protofiles and message marshallers
setValueMediaType(String) Same as keyMediaType but for values same default as above
Connecting to secure servers

The following properties can be used via ConnectorConfiguration.addHotRodClientProperty(prop, value) in order to connect to Infinispan server with security enabled:

Property Description
infinispan.client.hotrod.use_ssl Enable SSL
infinispan.client.hotrod.key_store_file_name The JKS keystore file name, required when mutual SSL authentication is enabled in the Infinispan server. Can be either the file path or a class path resource. Examples: "/usr/local/keystore.jks", "classpath:/keystore.jks"
infinispan.client.hotrod.trust_store_file_name The JKS keystore path or classpath containing server certificates
infinispan.client.hotrod.key_store_password Password for the key store
infinispan.client.hotrod.trust_store_password Password for the trust store

Basic usage:

Creating an RDD

Scala
import org.apache.spark.SparkContext
import org.infinispan.spark.config.ConnectorConfiguration
import org.infinispan.spark.rdd.InfinispanRDD

val sc: SparkContext = new SparkContext()

val config = new ConnectorConfiguration().setCacheName("my-cache").setServerList("10.9.0.8:11222")

val infinispanRDD = new InfinispanRDD[String, MyEntity](sc, config)

val entitiesRDD = infinispanRDD.values
Java
import org.apache.spark.api.java.JavaPairRDD;
import org.apache.spark.api.java.JavaRDD;
import org.apache.spark.api.java.JavaSparkContext;
import org.infinispan.spark.config.ConnectorConfiguration;
import org.infinispan.spark.rdd.InfinispanJavaRDD;

JavaSparkContext jsc = new JavaSparkContext();

ConnectorConfiguration config = new ConnectorConfiguration()
            .setCacheName("exampleCache").setServerList("server:11222");

JavaPairRDD<String, MyEntity> infinispanRDD = InfinispanJavaRDD.createInfinispanRDD(jsc, config);

JavaRDD<MyEntity> entitiesRDD = infinispanRDD.values();

Cache lifecycle control

Scala
import org.apache.spark.SparkContext
import org.infinispan.spark.config.ConnectorConfiguration
import org.infinispan.spark.rdd.InfinispanRDD

val sc: SparkContext = new SparkContext()

// Automatically create distributed cache "tempCache" in the server
val config = new ConnectorConfiguration()
                    .setCacheName("myTempCache")
                    .setServerList("10.9.0.8:11222")
                    .setAutoCreateCacheFromConfig(<infinispan><cache-container><distributed-cache name="tempCache"/></cache-container></infinispan>.toString)

val infinispanRDD = new InfinispanRDD[String, MyEntity](sc, config)

val entitiesRDD = infinispanRDD.values

// Obtain the cache admin object
val cacheAdmin = infinispanRDD.cacheAdmin()

// Check if cache exists
cacheAdmin.exists("tempCache")

// Clear cache
cacheAdmin.clear("tempCache")

// Delete cache
cacheAdmin.delete("tempCache")
Java
import org.apache.spark.api.java.JavaPairRDD;
import org.apache.spark.api.java.JavaRDD;
import org.apache.spark.api.java.JavaSparkContext;
import org.infinispan.spark.config.ConnectorConfiguration;

    .setCacheName("exampleCache").setServerList("server:11222")
    .setAutoCreateCacheFromConfig("<infinispan><cache-container><distributed-cache name=\"tempCache\"/></cache-container></infinispan>");

InfinispanJavaRDD<String, MyEntity> infinispanRDD = InfinispanJavaRDD.createInfinispanRDD(jsc, config);

JavaRDD<MyEntity> entitiesRDD = infinispanRDD.values();

// Obtain the cache admin object
CacheAdmin cacheAdmin = infinispanRDD.cacheAdmin();

// Check if cache exists
cacheAdmin.exists("tempCache");

// Clear cache
cacheAdmin.clear("tempCache");

// Delete cache
cacheAdmin.delete("tempCache");

Creating an RDD Using a custom Splitter

Scala
import org.apache.spark.SparkContext
import org.infinispan.spark.config.ConnectorConfiguration
import org.infinispan.spark.rdd._

val sc: SparkContext = ...

val config: ConnectorConfiguration = ...

InfinispanJavaRDD.createInfinispanRDD(jsc, config, customSplitter);

Creating a DStream

Scala
import org.apache.spark.SparkContext
import org.apache.spark.storage.StorageLevel
import org.apache.spark.streaming.{Seconds, StreamingContext}
import org.infinispan.spark.config.ConnectorConfiguration
import org.infinispan.spark.stream._

val sc = new SparkContext()
val config = new ConnectorConfiguration()
val ssc = new StreamingContext(sc, Seconds(1))
val stream = new InfinispanInputDStream[String, MyEntity](ssc, StorageLevel.MEMORY_ONLY, config)
Java
import org.apache.spark.SparkConf;
import org.apache.spark.streaming.Seconds;
import org.apache.spark.streaming.api.java.JavaStreamingContext;

import org.infinispan.spark.rdd.InfinispanRDD

val rdd: InfinispanRDD[String, MyEntity] = ???
val cache: RemoteCache[String, MyEntity] = ???

Query query = Search.getQueryFactory(remoteCache).from(MyEntity.class).having("field").equal("value").build();

JavaPairRDD<String, MyEntity> filtered = infinispanRDD.filterByQuery(query);

Filtering using Ickle Queries

Scala

InfinispanJavaRDD<String, MyEntity> infinispanRDD = InfinispanJavaRDD.createInfinispanRDD(jsc, conf);

JavaPairRDD<String, MyEntity> filtered = infinispanRDD.filterByQuery("From myEntity where field = 'value'");

Filtering by filter deployed in the Infinispan Server

Scala
import org.infinispan.spark.rdd.InfinispanRDD

val rdd: InfinispanRDD[String, MyEntity] = ???
// "my-filter-factory" filter and converts MyEntity to a Double, and has two parameters
val filteredRDD = rdd.filterByCustom[Double]("my-filter-factory", "param1", "param2")
