WL#11345: Increase default value of optimizer_trace_max_mem_size to a reasonable size
Affects: Server-8.0 — Status: Complete — Priority: Medium
optimizer_trace_max_mem_size: The maximum cumulative size of stored optimizer traces. The default value of optimizer_trace_max_mem_size is currently 16 kB, which means that it is truncated for any non-trivial query. This causes a lot of pain in the communication between development team and support, because many users are unaware that their optimizer traces are indeed truncated. The default value should be bumped to a larger value that accommodates most generated optimizer traces. Suggested new default value: 1 MB.
F1. Increase default value of optimizer_trace_max_mem_size from 16 kB to 1 MB. There are no non-functional requirements.
