Summary: Memory declaration API for UDF
Key: IOTDB-1392
URL: https://issues.apache.org/jira/browse/IOTDB-1392
Project: Apache IoTDB
Issue Type: Sub-task
Reporter: Steve Yurong Su
In some common function evaluation scenarios, it may be required to cache all
the original data in the memory, which may cause OOM. Obviously, the system
software should not allow such behavior.
We should provide a set of API (for example, used to apply for an array with
memory control) for user to declare memory usage. If the declared memory usage
is higher than the limit, we should reject the UDF evaluation and then throw an
exception.
