Hi Willem:
Thank you for you reply. Allow me to clarify the current situation of Doris. Please help us to confirm whether our understanding is correct. We rely on 3 third-party libraries. Their licenses are [1](GPL), [2](GPL), and [3](LGPL) respectively. We only link these third-party libraries, and the source code of these libraries is not included, nor used or modified in the Doris source kit. Among them, [1] and [2] are under GPL. The GPL itself is completely incompatible with the Apache License. But according to the description in [4], we can use these two libraries as optional components of Doris, and they are disabled by default. And even when these two libraries are disabled, users can still use Doris normally. Library [3] is under the LGPL. According to the rules of the LGPL agreement, as long as the [3]'s source code is not included in Doris, we can link and use this library.
