Shard¶

How to implement a new shard?¶

This section explains how to extend iden to support more shard implementations. iden has some built-in shard implementations, but it is quite easy to add additional implementations. A new shard can be implemented by extending the iden.shard.BaseShard class and implementing the following 5 methods:

clear
equal
get_data
get_uri
is_cached

Ideally, the instantiation of a shard object should be lightweight and the data should be loaded in-memory only when the get_data is called.
