trait FinatraReadOnlyKeyValueStore[K, V] extends ReadOnlyKeyValueStore[K, V]

A Finatra key value store that only supports read operations. Implementations should be thread-safe as concurrent reads and writes are expected.

    Get an iterator over a given range of keys.

    Get an iterator over a given range of keys. This iterator must be closed after use. The returned iterator must be safe from java.util.ConcurrentModificationExceptions and must not return null values. No ordering guarantees are provided.

    from

    The first key that could be in the range

    to

    The last key that could be in the range

    allowStaleReads

    Allow stale reads when querying (Stale reads can occur when querying key value stores with caching enabled).

    returns

    The iterator for this range.

    Exceptions thrown

    InvalidStateStoreException if the store is not initialized

    NullPointerException If null is used for from or to.
