It is possible to construct filters on the aggregate list that result in a large number of aggregates (> 1000). To display these aggregates on the aggregate list, they need to be retrieved from the customerdata service. This is achieved by sending an OData compliant message to the customerdata service, which consists of a filter looking like this:
Code Block |
---|
http://<host>:<port>/customerdata/api/v1/Aggregates?$filter=(aggregateId = <...>) or (aggregateId = <...>) or ...) |
...
When there are many aggregates (> 1000) this results in a very large call. The construction of this call, and the processing on the customerdata service side crashes when the number is larger than 1000 (it depends on the operating system and Java installation on what number exactly).
...
Please reconsider the modelling of the aggregate list and its filters to see if is possible to further limit the number of aggregates for that list. In most cases it does not make sense to model an aggregate list that displays so many records and if it does, it is likely to negatively impact the performance. When in doubt, please contact Blueriq support for help or discussing alternatives.

The steps below provide a workaround for the described problem. However, it is strongly discouraged to use this workaround in production as it will deteriorate performancecan negatively impact the performance of the whole Blueriq Runtime. You are advised to measure the (increased) memory usage of the Blueriq Runtime and Customerdata service and (re)size the RAM of the system accordingly. Blueriq cannot and will not guarantee acceptable performance with this workaround. | ||
