Hi Dr. Chang,
Good, thanks for useful suggestion. Now there is: https://issues.apache.org/jira/browse/HAWQ-1550
We are trying to integrate Hawq engine onto MaxCompute (former name ODPS, within Aliyun Cloud),
Seahawks, it is led by Mr. Chen Xia. We develop a component AXF (borrow idea from PXF) to
connect data sources from Druid and MaxCompute, it works well for this 11.11 battle, but it
is not stand-alone program.

Kuien, we are welcoming any good contributions from the community.
Looks hawq_log_master_concise is a good enhancement, I'd like suggest you create a JIRA and
we can discuss it on the JIRA.
Can you explain more about Druid Wrapper & MaxCompute Wrapper? What are the use cases

Hi Ed and Hawq,

I have add two GUCs (log_max_size, log_max_age) to control the logfile size on master, otherwise
the query to hawq_toolkit.hawq_log_master_concise will be slower and slower, and disk usage
on master is hard to constrain. If some gys are interested to this, I can submit it to Hawq.

Besides, our team has introduced many interesting features on hawq, but most of them are deep
coupling with Alibaba Cloud. Some of them may be (maybe not) seperated alone, such as Druid
Wrapper, MaxCompute Wrapper. I will discuss with teammates Mr. Chen Xia, Mr. Zhiyong Dai et

I feel we have sufficient content to warrant a release. It has been

4+ months since our last release ( I suggest we include the

pluggable storage feature (HAWQ-786 - assigned to Chiyang Wan -
chiyang10000@gmail.com) plus others (as appropriate) in the queue in

the next release.

Are there any outstanding issues that are mandatory for the release?

What do others think?
