org.apache.accumulo.core.client.Connector.createBatchWriter()
Factory method to create a BatchWriter connected to Accumulo. @param tableName the name of the table to insert data into @param maxMemory size in bytes of the maximum memory to batch before writing @param maxLatency time in milliseconds; set to 0 or Long.MAX_VALUE to allow the maximum time to hold a batch before writing @param maxWriteThreads the maximum number of threads to use for writing data to the tablet servers @return BatchWriter object for configuring and writing data to @throws TableNotFoundException when the specified table doesn't exist @deprecated since 1.5.0; Use {@link #createBatchWriter(String,BatchWriterConfig)} instead.
