It would be great to have an easy SQLite replication option to recommend (yeah, don't worry. we'll support other DBs eventually too). LiteFS (https://fly.io/docs/litefs/) looks like it could work. Someone should try it and let us know how it goes.

This is a guide that will get you started setting up the gateway and LiteFS on fly.io for testing purposes: https://blog.developerdao.com/running-an-arweave-gateway-on-flyio

Things we'd like to learn more about:

  • How quickly do blocks get indexed?
  • Is there much replication lag?
  • What errors do the readers throw? (they'll still be attempting some writes)
    • Do any of the errors result in user visible issues?

feat(db): add config option to support disabling DB writers #37
44add3e 
Adds an experimental config environment variable, START_WRITERS. It
defaults to 'true'. If set to 'false', worker processes that write to
the DB will be disabled. This is to support experimentation with SQLite
replaction via LiteFS.
