  39. def removeByValueCondition(store: StateStore, removalCondition: (UnsafeRow) ⇒ Boolean): Iterator[UnsafeRow]

    Removes using a predicate on values, with returning removed values via iterator.

    Removes using a predicate on values, with returning removed values via iterator.

    At a high level, this produces an iterator over the (key, value, matched) tuples such that value satisfies the predicate, where producing an element removes the value from the state store and producing all elements with a given key updates it accordingly.

    This implies the iterator must be consumed fully without any other operations on this manager or the underlying store being interleaved.

    removalCondition

    The predicate on removing the key-value.

  42. def updateSessions(store: StateStore, key: UnsafeRow, sessions: Seq[UnsafeRow]): (Long, Long)

    Replaces all sessions for the key to given one.

    key

    The key without session, which can be retrieved from extractKeyWithoutSession.

    sessions

    The all sessions including existing sessions if it's active. Existing sessions which aren't included in this parameter will be removed.

    returns

    A tuple having two elements

    1. number of added/updated rows 2. number of deleted rows
