Functions

purgeExpires

fun purgeExpires(entity_name: String, expiresAfter: Long)

purgeStale

fun purgeStale(entity_name: String, writeInstant: Long, readInstant: Long)

purgeStaleRead

fun purgeStaleRead(entity_name: String, readInstant: Long)

purgeStaleWrite

fun purgeStaleWrite(entity_name: String, writeInstant: Long)

transaction

fun transaction(noEnclosing: Boolean = false, body: SqkonTransactionScope.() -> Unit)

transactionWithResult

fun <R> transactionWithResult(noEnclosing: Boolean = false, body: SqkonTransactionScope.() -> R): R

updateReadForEntities

fun updateReadForEntities(readAt: Long, entity_name: String, entity_keys: Collection<String>)

Bulk-updates entity.read_at for entity_keys. An empty collection is a deliberate no-op: SQLite rejects IN () as a syntax error, and KeyValueStorage.updateReadAt routinely passes an empty list when a selectAll(...) Flow emits an empty result set.

upsertRead

fun upsertRead(entity_name: String, lastReadAt: Instant)

upsertWrite

fun upsertWrite(entity_name: String, lastWriteAt: Instant)
