I am trying to fetch 12000 records from DB using a Query rule I am getting the below error. Can I know what is the maximum limit I can set to conf.data.query.memory.limit in custom.properties
Error evaluating function 'queryruleexec' : Memory threshold reached during output conversion (rule: [Trust_getExistingTDAccountInfo], type: [TRUSTTDAccountInfoDT6885], threshold: [2,097,152 bytes], objects successfully converted: [1,687])) (Data Outputs)...

The amount of memory in bytes that will be consumed in the application server for a single query before the query is halted is configured using the following property in the custom.properties file:
conf.data.query.memory.limit=1048576

The default is 1048576 bytes (1 MB).

Instead of raising this value, I would recommend optimizing the query since raising the value can lead to performance problems.

The end of the rule specifies the amount of objects the rule retrieved before it reached the threshold ([1,687]). With this volume, small changes to the data (longer strings, etc.) can have a big effect on how much a query rule can bring back.
