Update RocksJava Wiki to include Logging Page about rocksdb

[adamretter]

How do we practically expect Java users to do that?

We would expect them to write C++, hence the "native" aspect. I have updated the wording to try and make that clearer.

Thanks for your work on this @neilramaswamy.

Seems like a good idea. What is your opinion on adding it to an existing page, or whether to add a new page in its own right? i.e. where do you think (as a user) it would best be found in the Wiki?

I think adding a "Logging" page under the RocksJava wiki would be best. The existing RocksJava Basics page is getting a bit long in my opinion, and this isn't really a basic feature -- the RocksDB logs certainly won't be useful for anyone with a "basic" use-case.

@neilramaswamy Thanks, I have added a page based on your example here - https://github.com/facebook/rocksdb/wiki/Logging-in-RocksJava

• I also adapted it to demonstrate a slf4j bridge.
• I tried to make the memory management responsibilities when using Logger clearer.

What do you think?

Just confused about one part:

but implementing your own native logger is also possible.

How do we practically expect Java users to do that? For our native logger changes, we have support over on the C++ side. If you're just suggesting that users can submit a PR to add another native logger, maybe that can be made more explicit. Currently, it sounds possible from RocksJava, but I don't think it is.

Otherwise, this is great!
