Yesterday, I talked about Impala Coordinator, which is scheduler layer of query execution.

My presentation document is here!

And @oza_x86 also talked about Impala Internal, but he focused on Query Execution Engine. The rest important component is only Query Planner. I hope someone presents Query Planner Internal at next event :)

@GedowFather presented Impala testing and operations on production(ja). This presentation shared the knowledge and application consideration. I think this presentation is testbed for Impala introduction.

Thanks to Hadoop User Group Japan for the good event!

P.S.

Currently, Impala doesn’t have a mascot or logo. @GedowFather produced the following image. I think this image is good candidate ;)
