Battle plan

[ric2b]

• [x] Have the mongos server accept a sharding key (don't do anything relevant with it)
  • [ ] ~enableGeoSharding~ (edit: is this even necessary? just use the normal enableSharding)
    • [x] ~Add the new command to the shell~
    • [ ] ~Add the new command to the mongos server~
      • [x] ~As a mockup~
      • [ ] ~Make it work~
  • [x] shardGeoCollection
    • [x] Add the new command to the shell
    • [x] Add the new command to the mongos server
      • [x] As a mockup
      • [x] Make it work (probably done. see below)
      • [x] Crashes the config server. Investigate (Might just be the balancer failing since it doesn't know what to do with a 2dsphere shardkey). I also reported it since it seems weird for a server to be able to crash another one.
  • [x] Have the balancer work in a very naive way, like splitting lattitude equally among shards
    • [x] Find the code that inserts data: Note: There are 2 code paths for insert, depending on if sharding is enabled or not
    • [x] Find the balancer code that manages shards
    • [x] Find the code that keeps shard information and get shard Id's or similar
    • [x] Modify the balancer to shard naively
  • [x] Test the implementation so far

2. Have the mongos server accept a shard tag (don't do anything relevant with it)

3. When inserting, use the shard key and shard tags to decide where to insert

4. When querying, use the shard key and shard tags to decide where to query
