PARTITION makes splitting up the data mostly transparent. Sharding requires that your code do all the work. There are some third party products on the market that makes sharding transparent to you.
Suggest you make an abstraction layer now, before launching into sharding. This layer would receive not the SQL statements, but an abstraction of such. With your current implementation (PARTITION), the layer would turn the abstract request simply into SQL and hit your one table.
Once you have debugged that, then consider sharding. Now, the layer would look at the tweet_id, hash it to decide which server to hit connect to _that_ server, and finally issue the SQL.
