Hello, how do we associate the directory with the partition? I read that the broker uses meta.properties to do that; could you give more information on this?

Currently, the tests pass without the condition that there exists a partition record containing the UUID of the directory it is associated with. Because I don’t know where to get that directory, I can’t fulfil that condition, so the tests may fail at some point in the future.

Thanks

Hey @samer-hamood, the short answer is that you don’t need to associate the partition with a directory here, it’s already [associated in the metadata](https://binspec.org/kafka-cluster-metadata?highlight=239-254).

You also don’t need to validate the directory UUID for this stage, because the existing data is already valid.

If you’re interested, I’ve opened [a PR](https://github.com/codecrafters-io/binspec/pull/37) explaining this in more details.

Let me know if you’d like any further clarification!

@samer-hamood To answer your question about “where to get that directory”:

Note that your broker is started with the configuration file `/tmp/server.properties`:

Inside /tmp/server.properties, you’ll find:

```auto
log.dirs=/tmp/kraft-combined-logs

```

In general, multiple directories can be specified as a comma-separated list.

To locate the relevant directory, iterate through the paths listed in log.dirs and inspect the `meta.properties` file inside each directory.
