Re: AntsDB is released with MySQL compatibility for HBase
Hi, my advise is to change it to APL from now before you start having contributors, a project with contributors will need written permission from each to change the license.

Re: AntsDB is released with MySQL compatibility for HBase
Well, I didn’t expect the license has become the concern instead of the software itself. So I did my homework trying to have a good understanding of the license. So GPL means you need to open source derived work as long as you make the software public, even by dynamically linking to a GPL library. Sounds pretty good to me personally. I have no issue with that. Sure I understand it can be bitch to make a profitable business on top of that. LGPL means you can link to a LGPL library without publishing derived work. As of today, AntsDB does more than linking to the MySQL JDBC driver. There are private members of the network protocol implementation in the JDBC driver that I use. Yah I mean i copied some of the source code for the sake of laziness. But don’t let license hold your feet. I own 100% of the source code. If the community find good use of my program, I’d be more than happy to overcome my laziness and rewrite the GPLed code, making it LGPL. ~water > On May 9, 2018, at 1:59 PM, Sanel Zukan wrote: > > What about Connector/J from MariaDB?

Re: AntsDB is released with MySQL compatibility for HBase
LGPL is not compatible with ASL, either. See: https://www.apache.org/ legal/resolved.html#category-x -Dima On Wed, May 9, 2018 at 10:59 AM, Sanel Zukan wrote: > What about Connector/J from MariaDB?

Re: AntsDB is released with MySQL compatibility for HBase
What about Connector/J from MariaDB? It is LGPL and (I think) that should make it easier to mix with Apache license. Best, Sanel Water Guo writes: > I am not an expert with software license.
