    Description

      Since topic logs are stored in a directory holding the topic's name, creation of the directory might fail for large strings.
      This is not a problem per-se but the exception thrown is rather cryptic and hard to figure out for operations.

      I propose fixing this temporarily with a hard limit of 200 chars for topic names, it would also be possible to hash the topic name.

      Another concern is that the exception raised stops the broker, effectively creating a simple DoS vector, I'm concerned about how tests or wrong client library usage can take down the whole broker.
