Subject [PROPOSAL]: deprecating create region using --template-region option
Date Wed, 07 Feb 2018 17:49:24 GMT
Hi, All,

currently, there are two ways to create a region, either to use a "--type"
option indicating a region shortcut or a "--template-region" option
specifying another regionPath where you want to copy the attribute from.

First of all, we are not sure what set of attributes that make sense to
copy to the new region. e.g listeners/loaders/writers, normally these are
connected to a downstream database that user may/may not want the new
region to read/write the same table. And the current implementation would
fail to create a region from a template that has these custom callbacks
(including listeners, loader, writer, compressor, resolvers etc). So we
would like to understand how useful this command option is and if we can
stop supporting it?

Suggestions/feedback welcome!
