Added async writes / batching by default

[doomerhunter]

Hi there :)

First, thanks for taking the time to maintain this extension and for the rewrite under the montoya API :)

In the past, when using the extension on large bug bounty targets and extensive sessions, I had some performance issues, notably with scans or when browsing in parallel with different browsers / sessions.

I would like to implement a couple of new features in this extension amongst which :

• 1/Async writes to the DB
• 2/The ability to batch push requests to a postgreSQL database.
• 3/Some additional configuration options on the type of traffic to be logged (ex: being able to exclude intruder traffic temporarly)

This pull request implements 1/Async writes to the DB by modifying src/main/java/burp/ActivityLogger.java

Disclosure: I (really) suck at Java, so this code was generated through the help of Claude 4. I then proceeded to test the code through building it and stress-testing the extension (multiple browsers, directory brute-force through intruder...).

Hi @doomerhunter

First of all, thank you very much for your contributions. I really appreciate and honestly, did not think that anyone would contribute in that short time after the transfer of ownership :).

In my opinion, it would be best to have separate PR for each new feature. This way we could discuss the points in a modular way and do not block other features. Therefore, I will close #4 without merging. I hope that is fine for you. Furthermore, would it be possible for you to "untangle" the different PRs? I currently see here the commits "First iteration of the tool filtering feature" and "added a better interface to select the tools we wish to include". Thus, this PR already contain two different features.
Secondly, I would need to discuss some organizational matter with you; would it be possible to write me an email? (My email is dominique.roux@protonmail.com)

For this specific feature: I will check out the code and also do some testing prior to merging. The general feature sounds nice and I have no general objection or remarks there.
