mz.aggregation.storage.maxneedssync

Default value: 5000

This property defines when updated aggregation sessions shall be moved from the cache to the file system. When the number of cached aggregation sessions reaches this value, the sessions are written to disk.

This property shall be set to a value lower than "Max Cached Sessions", configured in the Aggregation agent. If the property is set to a higher value, the used value will be "Max Cached Sessions" minus 1. For example, if "Max Cached Sessions" is "6000" and this property is set to "6500", the value "5999" will be used instead.

For performance reasons, this property should be given a reasonably high value, but consider the risk of a server restart. If this happens, the cached data might be lost.

mz.aggregation.storage.profile_session_cache

Default value: false

This property is used to speed up the start of workflows that run locally (on the EC). Set the property to true to keep the aggregation cache in memory for up to 10 minutes after a workflow has stopped.

mz.aggregation.timeout.threads

Default value: 0

This property is used to enable Multithreading in Aggregation workflows, that is, to use a thread pool for the timeout function block in the Aggregation agent. Use a value larger than 0, for example, 4 to use four threads in the thread pool.
