-<p>If you’re a Kylin administrator but new to Spark, suggest you go through <a href="https://spark.apache.org/docs/1.6.3/">Spark document</a>, and don’t forget to update the configurations accordingly. Spark’s performance relies on Cluster’s memory and CPU resource, while Kylin’s Cube build is a heavy task when having a complex data model and a huge dataset to build at one time. If your cluster can not match the requirement, kinds of error like “OutOfMemorry” will be thrown in executors, so please use the new engine properly. For Cube which has many combinations (e.g, a full cube with more than 12 dimensions), UHC, or memory hungry measures (Count Distinct, Top-N), suggest to keep using the MapReduce engine. If your Cube model is simple, all measures are SUM/MIN/MAX/COUNT, source data is small to medium scale, Spark engine would be a good choice. Besides, Streaming build isn’t supported in Spark engine so far (KYLIN-2484).</p>
