Is your feature request related to a problem or challenge? Please describe what you are trying to do.

The initial EXPLAIN support was merged in #1293 , but the EXPLAIN ANALYZE portion is not implemented yet. This issue tracks the remaining work needed to support it.

Describe the solution you'd like The exact design is still TBD, but the general direction is to create a new exec to gather per-executor metrics from scheduler so we can generate a full EXPLAIN ANALYZE output

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
