# Hash Map

<warning>
Outdated Section - will be updated soon!
</warning>

UCX provides a basic hash map implementation with a configurable amount of buckets.
If you do not specify the number of buckets, a default of 16 buckets will be used.
You can always rehash the map with `cxMapRehash()` to change the number of buckets to something more efficient,
but you need to be careful, because when you use this function you are effectively locking into using this
specific hash map implementation, and you would need to remove all calls to this function when you want to
exchange the concrete map implementation with something different.
