By default, the thread limit is set to 4. This setting governs how many nodes are able to execute concurrently for a given execution.
If needed, you can override the default setting by adding the following line to your cust.prop file, and editing the number "4" as required:
ls.brain.controller.farm=( "${ls.brain.server.host=localhost}:${ls.brain.server.port}:4" )
The cust.prop file can be found at:
<Data360Analyze site configuration directory>/cust.prop
Tip: Increasing the number of controller farm threads will only have an impact on performance if there are enough parallel paths (branches) in your data flow to allow more nodes to be run concurrently. That is, this setting will have no affect on nodes whose execution depends on a previous node due to a connection or run dependency; in these cases the dependent nodes in a branch will still be run sequentially regardless of any change to this setting.
