09/01/2023, 1:35 PMwhat is your question?
MiddleManager is in fact the 'real time' node, if that was the question
Renato Santos
09/01/2023, 1:36 PMbut pretty much always you will need a historical node as well, even if you only to query 'real time'
maybe you can upgrade to latest version, druid 27, where you can have pretty much 'no historical loaded but still queryable if needed' but that's pretty new

09/01/2023, 3:40 PMHi Saurabh,
To add to what Renato said --
The "real-time" query is served specifically by each streaming ingestion task. Each ingestion task has around 5 JVM threads ... three are used for the data ingestion process and two are used to serve queries.
Ingestion tasks are JVMs spawned by the Middle Manager and live on the same node as the MM.
