The default is 1048576 bytes (1 MB). Before changing this value, consider using the query rules paging parameter to return less data (or return data in batches) and therefore avoid the limit. Also, consider whether the entire set of data that is being returned is actually needed. If not, use the query expression functions to select which fields to return

Limit here is 1 MB . To overcome this problem fetch data in batches.

Yes, Jaishankar. I agree with you. We need to consider 1 MB data and/or query timeout (default 10 seconds)

Agree with default of 1MB (faced that many times). Adding to this one and related to error we get - I have faced error message even when there is slow response due to query. One should look into logs to understand whether the error is related to size of data retrieved OR response time.

It is 1MB (default) limit and it can be increased, when increasing this value, apply a corresponding increase to the maximum memory heap size of JVM for the application server.

Hi, There is no such limitation for retrieving the data using the a!queryEntity() function. please check:

Hi rakshandad,

As per my understanding, There is no limit for retrieving the data from a query entity, but it takes time to load the data,if it is in a large size. Please refer to the below link
docs.appian.com/.../Expression_Rules.html

when there are data in larger size. we usually got error mesage like " Error while retriving data". on forum Query rule fetching limit has been mentioned. but i dont see any limit specified for Query Entity.

Philb pointed correctly. For each query, there is a memory threshold. That is the reason we should always use precise number of fields in the CDT to be queried and always use paging.

Interesting question - I think it's the same as for a query rule - that limit is documented here: docs.appian.com/.../Post-Install_Configurations.html
