    • asyncAdd

      public org.apache.flink.api.common.state.v2.StateFuture<Void> asyncAdd(W window, org.apache.flink.table.data.RowData value)
      Updates the operator state accessible by asyncGet(W) by adding the given value to the list of values. The next time asyncGet(W) is called (for the same state partition) the returned state will represent the updated list.

      If null is passed in, the state value will remain unchanged.

      Parameters:
      window - The namespace for the state.
      value - The new value for the state.
