Struct StoreConfig 

pub struct StoreConfig {
    pub durability: Option<DurabilityTier>,
    pub volume: Option<String>,
    pub evict_after: Option<u64>,
    pub retention_class: Option<RetentionClass>,
    pub compression: Option<bool>,
    pub flush_interval_ms: Option<u64>,
}

@store directive — storage-engine axis.

Bare @store (no args) inherits all defaults. Each field is optional; omitted fields fall back to platform defaults.

Fields

durability: Option<DurabilityTier>

@store(durability: ...). None = platform default (currently Soft for user data; Strong for system databases like yeti-auth, yeti-queue).

volume: Option<String>

@store(volume: ...). None = use the app’s default volume. When set: if the value starts with / or contains ://, treat as a literal path/URL; otherwise resolve through yeti-config.yaml storage.volumes. Reserved value "adaptive" is parsed but rejected at backend open until Ships adaptive-tier storage.

evict_after: Option<u64>

@store(evictAfter: N) — seconds before a record is evicted. Replaces the older @table(expiration: N) arg.

When @store(class:) is set, the loader resolves the class to its canonical window (see RetentionClass::evict_after_secs) and stores the result here, so every downstream consumer reads a single evict_after seconds value regardless of how the schema expressed retention. Declaring both class and a raw evictAfter is a schema error — the two are mutually exclusive.

retention_class: Option<RetentionClass>

@store(class: "hot|warm|audit-archive") — the named retention class this table opted into, if any. Kept alongside the resolved Self::evict_after so tooling can report the operator’s declared intent, not just the derived seconds.

compression: Option<bool>

@store(compression: bool) — per-table override of the deployment-wide compression setting.

flush_interval_ms: Option<u64>

@store(flushIntervalMs: N) — bounded crash-loss window in ms. Provides a fourth point on the durability scale between lossy (~minutes) and soft (~seconds): periodic fsync() of the WAL every N ms. Mutually exclusive with durability: "strong" (already fsync-per-write) and durability: "lossy" (no WAL to fsync). Runtime wiring to RocksDB’s wal_bytes_per_sync / background SyncWAL is deferred — this commit lands the directive surface so schemas can declare it.
