Hi all, In my river, I would like to access mapping information based in the fields. Example: Having this mapping: { "tweet" : { "properties" : { "message" : {"type" : "string", "store" : "yes", "enabled": false} } } } I would like to do this... ClusterState cs = client.admin().cluster().prepareState().setFilterIndices("my\_index").execute().actionGet().getState(); IndexMetaData imd = cs.getMetaData().index("my\_index"); MappingMetaData mdd = = imd.mapping("my\_type"); HashMap \ mapped\_node = mdd.getMapByPath("message"); ... and then get the type, store and enabled as mapped\_node keys, with the corresponding value. Is this possible? ---

You will need to parse it yourself from the compressed string that its stored internally, but I will add a method to return it as Map.

Thanks Shay for the fast answer! We already parse the mapping ourselves, but it will be easier with a Map!
