vrajat opened a new issue, #14624:
URL: https://github.com/apache/pinot/issues/14624
Reproduce:
* Start `MultiStageQueryEngineQuickStart`.
* Run the following commands:
```
# Run query using SSE
curl --request POST http://localhost:9000/sql --data '{"sql":"SELECT
playerName, teamID FROM baseballStats_OFFLINE LIMIT 10",
"queryOptions":"useMultistageEngine=false"}' | jq > /tmp/sse
# Run query using MSE
curl --request POST http://localhost:9000/sql --data '{"sql":"SELECT
playerName, teamID FROM baseballStats_OFFLINE LIMIT 10",
"queryOptions":"useMultistageEngine=true"}' | jq > /tmp/mse
```
The relevant portions of diff are:
```
diff /tmp/sse /tmp/mse
67,68c131,132
< "numServersQueried": 1,
< "numServersResponded": 1,
---
> "numServersQueried": 0,
> "numServersResponded": 0,
```
Note that lines starting with `>` are from `/tmp/mse`
Other fields are set to 0 as well but it is not clear to me if the time
taken was > 0 ms.
