Does pinot allows the users claim a query id together with the query? More general question is how to set up query context like Druid did? I cannot find the relevant doc. It will be convenient for tracing among different systems.

Regarding query context, that looks to be similar to query options for Pinot (though naturally the options are not 1:1 with Druid): https://docs.pinot.apache.org/users/user-guide-query/query-options I’m less sure about the concept of a query ID

no queryID in pinot side, which is painful for debugging.
