What MongoDB shard key strategy should i follow, for following composite document id,
there may be multiple document for _id.id and _id.servicePath.
I want to distribute data with "_id.id": "DeviceEntity1" and "_id.id": "DeviceEntity2"in two MongoDB shards.
"_id" :
{ "id" : "DeviceEntity1", "type" : "DeviceEntity", "servicePath" : "/raw" },...
Thank You.
