Thank you all for attending the hangout today.

Here are the meeting minutes:

Muhammed asked question about how the client chooses which drillbit to conn=
ect.
Client gets the information about available drillbits from zookeeper and
just does round robin to select the node for a query. That drillbit becomes=
 the foreman for the query.

Paul discussed in detail the memory fragmentation problem we have in drill =
and how we
are planning to address that. It was very insightful. Thanks Paul.
You can refer to DRILL-5211<https://issues.apache.org/jira/browse/DRILL-521=
1> for more details. It has links to background information and design docs=
.
Please ask questions and provide comments in the JIRA.

For the next meeting, we can choose another topic like this and go in detai=
l.

Thanks,
Padma
