### What about alternative libraries?
The only real alternative library that I am aware of is [ring-ttl-session](https://github.com/luminus-framework/ring-ttl-session)
The only real alternative library that I am aware of at this time is [ring-ttl-session](https://github.com/luminus-framework/ring-ttl-session)
which is built on top of [ExpiringMap](https://github.com/jhalterman/expiringmap). For the most part this works well,
but `ExpiringMap` has a number of issues with thread-safety (a couple of which I have hit recently) that have been
unresolved for a long while now. Which is unfortunate as it's otherwise a great looking library!
and if your web app is like most web apps out there and you're only ever interacting with your session store via the
three methods found on Ring's `SessionStore` protocol (`read-session`, `write-session` and `delete-session`) then you
likely will be very well served with ring-ttl-session.
On the other hand, if you have more in-depth needs and do things such as inspect/iterate through the underlying session
map to find sessions matching certain criteria (for example), then `ExpiringMap`s unresolved thread-safety issues will
very quickly become apparent and you will probably need to find an alternative solution.
