MV Assistant
Specifying the Spark-related configurations of each MV is a very important step toward improving the MV loading time and performance. However, it is not a simple task to identify the appropriate value combination of these configurations. The 2022.9.0 release introduces the MV Assistant feature to facilitate identifying the appropriate values for each MV. When the feature is enabled, Incorta collects various metrics during each MV load job, analyzes these metrics, and simulates different values to identify and recommend the optimal value combination.
Note
The MV Assistant is a preview feature in the 2022.9.0 release.
The MV Assistant mainly consists of a Spark Listener, a Heuristics Recommender, and a Cleanup job.
- The Spark Listener collects the required metrics while running the Spark application of an MV load job, simulates different values of the Spark configurations, and saves the output to a file in the following path:
<TENANT_NAME>/mvlenslogs/pending/<SCHEMA_NAME>/<TABLE_NAME>/. - The Heuristics Recommender uses the output file created by the Spark Listener and applies several heuristics to find the most optimal set of values and saves them to the metadata database. After using the output file, it is moved to the
<TENANT_NAME>/mvlenslogs/archived/<SCHEMA_NAME>/<TABLE_NAME>/. directory. - The Cleanup Job, when enabled, deletes the archived files that the Heuristics Recommender has already used after a specific number of days or after reaching the maximum number of archived files to keep. For details, see the MV Assistant Properties
The following are the configurations that the MV Assistant analyzes and recommends new values for.
- Executor instances (
spark.executor.instances): The total number of executors to allocate for the application - Executor cores (
spark.executor.cores): The number of cores per each executor - Executor memory (
spark.executor.memory): The amount of memory to be allocated for each executor - Shuffle partitions (
spark.sql.shuffle.partitions): Determines how many partitions should the data be partitioned into after shuffling
Recommended values are saved to the metadata database per MV and are introduced via a dedicated dashboard. Schema developers can manually apply the recommended values per MV.
Note
Contact Incorta Support to get the required assets.
Feature limitations
- The MV Assistant runs on the level of a single MV. Only one instance of the MV Assistant can run per tenant at a time.
- Recommended values cannot be automatically populated to the related MV or other MVs. You have to set them manually.
- This feature aims at enhancing the MV loading time and performance regardless of the cost and resources; however, they will be limited to the defined configurations.
- The MV Assistant does not consider the cluster size.
- The MV Assistant does not currently support the dynamic resource allocation option at the MV level or system-wide and is intended for those customers managing MV resource allocation with default configuration plus overrides at the individual level.
- The recommended values are for both full and incremental load jobs.
Note
- The MV Assistant introduces recommendations when there is a chance of improvement in the loading time and performance, otherwise, it will introduce no recommendations.
- The improvement percentage and value are approximate.
- The MV Assistant consumes a very minor amount of system resources during each MV job submission.
