Example 6 with OperandPolicy

use of org.scale7.cassandra.pelops.OperandPolicy in project scale7-pelops by s7.

the class Pelops method addPool.

/**
	 * Add a new Thrift connection pool for a specific cluster and keyspace. The name given to the pool is later used
	 * when creating operands such as <code>Mutator</code> and <code>Selector</code>.
	 * @param poolName				A name used to reference the pool e.g. "MainDatabase" or "LucandraIndexes"
     * @param cluster				The Cassandra cluster that network connections will be made to
     * @param keyspace				The keyspace in the Cassandra cluster against which pool operations will apply
     * @param policy                The configuration used by the pool
     * @param operandPolicy         The configuration used by the {@link org.scale7.cassandra.pelops.Operand}
