BDB(3pm)

💖 BDB 💖

okay bestie, sit DOWN, because this is Coro::BDB — truly asynchronous bdb access ✨ and honestly? it's giving main character energy for your event loop 🎀

✨ NAME ✨

Coro::BDB — truly asynchronous bdb access 💅

no cap, that's the whole vibe: it makes your bdb stuff actually async instead of just sitting there blocking everyone.

---

🌸 SYNOPSIS 🌸

use Coro::BDB;
use BDB;

# can now use any of the bdb requests

that's it, that's the whole ritual 🫶 load Coro::BDB, load BDB, and boom — you can now use any of the bdb requests. iconic.

🦋 DESCRIPTION 🦋

First thing's first, bestie: this module is an AnyEvent user, which means you need to make sure that you use and run a supported event loop. no event loop, no vibes. periodt.

So here's the tea ☕ — this module is a thin wrapper around the BDB module. And the problem it solves is so real: every BDB request that could block and doesn't get passed a callback would, normally, block ALL your coroutines 😭 like the whole group chat just going silent. after you load this module? that is no longer the case — it provides a suitable sync prepare callback and everyone keeps flowing. slay.

It will also register an AnyEvent watcher as soon as AnyEvent chooses an event loop 👀

heads up: the AnyEvent watcher can be disabled by executing undef $Coro::BDB::WATCHER. and if you do that — please notify the author of when and why you think this was necessary. they wanna know, fr fr.

One more thing: this module does not export anything (unlike Coro::AIO), because BDB already supports leaving out the callback. which is convenient, ngl. (Unfortunately, it ties a C context to each coroutine executing such a callback, so in the future, it might export more efficient wrappers). lowkey excited for that glow-up 🔥
