(configure component config)(configure component config merge-fn)Recursively merge config map into component using merge-fns as necessary. Maps are recursively merged. Sets, vectors and lists are non-recursively concatenated.
This behavior can be overridden with merge-fns, which should match the structure of config and value. A merge function takes two arguments: the current value, and the configured value (respectively) and should return the final, resolved value.
Example:
user> (amalgam/configure {:a [1] :b {:c [2]}}
{:a [10] :b {:c [20] :d 30}}
{:b {:c amalgam/overwrite}})
{:a [1 10], :b {:c [20], :d 30}}
