Semantic Model: spark.dynamicAllocation.maxExecutors

Description:
This property specifies the maximum number of executors Kyvos could launch during the Spark jobs in the semantic model process. When Kyvos submits a semantic model process or data profile job to Spark, it delegates this property value to the same-named property of Spark.

Values and behavior:
Any positive integer.

Default value:

100 - At most, these many executors will be launched during a Spark job.

Scope:

• Connection: If the property is set at the connection, then the property value is applicable for all semantic model processes or data profile jobs launched using Spark.

• Semantic model: If the property is set on a semantic model, then the value will override the connection level value for that semantic model’s job.

Comes into effect:

This property comes into effect only when kyvos.build.execution.engine is set as Spark. The value of the property can be changed at any time and will be respected in the next semantic model job.

Dependencies and related properties:

• kyvos.build.execution.engine

• spark.dynamicAllocation.minExecutors

• spark.executor.cores

• spark.executor.memory

• Semantic Model: spark.yarn.executor.memoryOverhead
