Expand description
sqlite-WAL cold adapter for the Durability-Service (ADR 0009) — the
default PERSISTENT backend.
Crate zerodds-durability-store-sqlite. Safety classification: STANDARD.
ACID via PRAGMA journal_mode=WAL; synchronous=NORMAL (crash-safe without
an fsync per insert). One row per sample; the (topic, instance, sequence)
primary key makes re-sends idempotent. Retention follows the topic
Contract (set via DurabilityStore::set_contract); contracts live in
memory and are re-registered by the daemon on startup, while the samples
themselves survive a full process/system restart in the database file.
For analytics, open the same .db with any SQL tool — the schema is
stable and documented here (ADR 0009: adapters expose their own native
read interface alongside the DDS path).
