topkAdd
Description copied from interface:ReactiveTransactionalTopKCommands
Execute the command TOPK.ADD. Summary: Adds an item to the data structure. Multiple items can be added at once. If an item enters the Top-K list, the item which is expelled is returned. This allows dynamic heavy-hitter detection of items being entered or expelled from Top-K list. Group: top-k- Specified by:
topkAdd
in interfaceReactiveTransactionalTopKCommands<K,
V> - Parameters:
key
- the name of list where item is added, must not benull
item
- the item to add, must not benull
- Returns:
- A
Uni
emittingnull
when the command has been enqueued successfully in the transaction, a failure otherwise. In the case of failure, the transaction is discarded.
-

when the command has been enqueued successfully in the transaction, a failure otherwise. In the case of failure, the transaction is discarded.
-
topkIncrBy
Description copied from interface:ReactiveTransactionalTopKCommands
Execute the command TOPK.INCRBY. Summary: Increase the score of an item in the data structure by increment. Multiple items' score can be increased at once. If an item enters the Top-K list, the item which is expelled is returned. Group: top-k- Specified by:
topkIncrBy
in interfaceReactiveTransactionalTopKCommands<K,
V> - Parameters:
key
- the name of list where item is added, must not benull
item
- the item to add, must not benull
increment
- increment to current item score. Increment must be greater or equal to 1. Increment is limited to 100,000 to avoid server freeze.- Returns:
