bq. What if I to have a clean 'id' value which is devoid of extra information?
Should I do id.substring(id.indexOf("!") everytime I use it elsewhere ?
Why would you have to do that? If "!" appears in the ID field by accident
sometimes, everything still works as expected with the compositeId router -
that's why it's the default.
edit: Oh, I think I see what you mean... you want to use the id unchanged as a
foreign key. You could always store that as a separate field too. Anyway, I'm
not arguing against using another field, but I do think it's the less common
and more complex solution (given that you now need to provide that extra value
everywhere).

> We should be able to create a collection where sharding is done based on the
> value of a given field
> collections can be created with shardField=fieldName, which will be persisted
> in DocCollection in ZK
> implicit DocRouter would look at this field instead of _shard_ field
> CompositeIdDocRouter can also use this field instead of looking at the id
> field.
