feat(transactions): Explicit (and faster) database transactions Summary: Until now, we've been hiding transactions beneath the surface. When you call persistModel, you're implicitly creating a transaction. You could explicitly create them with `atomically`..., but there were several critical problems that are fixed in this diff: - Calling persistModel / unpersistModel within a transaction could cause the DatabaseStore to trigger. This could result in other parts of the app making queries /during/ the transaction, potentially before the COMMIT occurred and saved the changes. The new, explicit inTransaction syntax holds all changes until after COMMIT and then triggers. - Calling atomically and then calling persistModel inside that resulted in us having to check whether a transaction was present and was gross. - Many parts of the code ran extensive logic inside a promise chained within `atomically`: BAD: ``` DatabaseStore.atomically => DatabaseStore.persistModel(draft) => GoMakeANetworkRequestThatReturnsAPromise ``` OVERWHELMINGLY BETTER: ``` DatabaseStore.inTransaction (t) => t.persistModel(draft) .then => GoMakeANetworkRequestThatReturnsAPromise ``` Having explicit transactions also puts us on equal footing with Sequelize and other ORMs. Note that you /have/ to call DatabaseStore.inTransaction (t) =>. There is no other way to access the methods that let you alter the database. :-) Other changes: - This diff removes Message.labels and the Message-Labels table. We weren't using Message-level labels anywhere, and the table could grow very large. - This diff changes the page size during initial sync from 250 => 200 in an effort to make transactions a bit faster.
