kudu resource/hardware question

[Amit Adhau <am...@globant.com>]

Hi Team Kudu,

I am not sure if it is a valid question or not, but their is below query,
which came up to me.

Does Kudu uses the Impala query engine when we make a call to kudu tables
via Impala JDBC as well as via Kudu java API, if yes is their any impact at
resources and performance levels if it shares the Impala engine.

Thanks,
Amit

Hi Amit,

Access to Kudu via the Impala JDBC interface do go through Impala, and
should be accounted for in Impala resource and capacity planning.  Access
to Kudu via the Kudu Java client API do not go through Impala, and
therefore do not need to be accounted for in Impala capacity planning.
Usage of Kudu through Impala and through direct Java client access share
Kudu, and therefore both should be accounted for when capacity planning for
Kudu.

Hope this answers your question,
Dan
