Subject Upgrade from 2.4.1 to 2.6.1
Date Thu, 14 Mar 2019 14:40:27 GMT
Now that 2.6.1 is launched, we are planning an upgrade (with a transition
period and an extensive test plan) from 2.4.1. I have a few questions for
developers and / or system administrators.

- Do you recommend use mysql as kylin metadata storage? Until now, most of
our problems are related with hbase since we rebuild cubes very frequently
and kylin_metadata table grows a lot. Do you notice performance loss or
gain? Is it stable enough?

- If using mysql as metadata backend, can we export / import metadata in
order to migrate from hbase to mysql without having rebuild existing cubes?

Thanks in advance.
