SqliteCheckpointerConfig

How a SqliteCheckpointer uses its database connection.

busyTimeout is how long a write waits for the database's write lock while another connection - another store over the same file, in this process or another - holds it, before the call fails. SQLite allows one writer at a time per file, and every write here is short (one transaction per call), so a wait is brief; a call that still times out returns a ProcessingError and changes nothing. It is rounded up to whole milliseconds, and must be positive and at most Int.MaxValue milliseconds: apply and the with* setters throw IllegalArgumentException otherwise, and SqliteCheckpointerConfig.of returns a ValidationError.

The journal mode and sync level are not configurable: the store always runs in WAL mode with synchronous = FULL, so readers never block the writer and a commit that returned survives a power loss.
