The HDF5 plugin modified the protobufs but I wouldn’t think that would cause
this.

Hi Paul,
The total query execution time itself is not crossing 18 secs which
includes 1.9 secs of planning time. But going through the profile to see
where is the
time being spent, we saw 6 secs for "setup time" like above.
How different is "setup time" from planning time?

Sorry I couldn't keep this shorter. But I'll get right to the point:

Did a quick check of the source code. The GetServerMetaResp protobuf message
has not changed recently.
Does anyone on the team know if we changed any Protobuf messages and either
added or removed non-optional fields?
Thanks,

Hi,
Welcome to the Drill mailing list.
You are right. Drill is a SQL engine. It works best when the JSON input files
represent rows and columns.
Of course, JSON itself can represent arbitrary data structures: you can use it
to serialize any Java structure you want. Relational tables and
Hi Aditya,
While I cannot comment on MapR-DB in particular, I can say that, in general,
Drill is designed for fairly large queries. There is a trade-off between the
overhead of code gen and planning vs. the cost at runtime. Drill tends to
invest more in up-front planning and code gen to
Hi Hema,
Welcome to Drill! Drill's primary use case is to run distributed queries across
multiple nodes. For that, Drill generally runs as a stand-alone process,
perhaps launched by YARN, Docker, K8s or your own scripts. Although Drill runs
in embedded mode, this is mostly to provide a "quick

Can you share the python code?

I had Drill 1.16 running in embedded mode and it was running without error.
After just switching to the 1.17 tarball and running in embedded mode, I
seem to get these warnings after running queries using ODBC and Python
(always 4 of them, exact same message):
[libprotobuf ERROR
Hi,
Some JSON file are complex and containing differents "tree struct".
If these file are big it will take too much time for drill to align the
structures (and even worse sometimes fail).
In spark it's possible to force a schema when reading a file to avoid long or
useless treatment of align
Team,
Is there a way to reduce the "setup time" for a minor fragment?
In my case, it's Drill on Mapr-db JSON table.
As per documentation, it is time consumed for "runtime code generation and
opening a file".
While going through a query profile i see below:
Minor Fragment Hostname Setup Time
