topkAdd
public void topkAdd(K key, V item)
Description copied from interface:TransactionalTopKCommands
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 interfaceTransactionalTopKCommands<K,V>
- Parameters:
key
- the name of list where item is added, must not benull
item
- the item to add, must not benull
-
topkAdd
public void topkAdd(K key, V... items)
Description copied from interface:TransactionalTopKCommands
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.

- Parameters:
key
- the name of list where item is added, must not benull
items
- the items to add, must not benull

-
topkIncrBy
public void topkIncrBy(K key, V item, int increment)
Description copied from interface:TransactionalTopKCommands
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:

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.

-
topkReserve
public void topkReserve(K key, int topk, int width, int depth, double decay)
Description copied from interface:TransactionalTopKCommands
Execute the command TOPK.RESERVE. Summary: Initializes a TopK with specified parameters. Group: top-k- Specified by:
topkReserve
in interfaceTransactionalTopKCommands<K,V>
- Parameters:
key
- the name of list, must not benull
topk
- the number of top occurring items to keep.width
- the number of counters kept in each array. (Default 8)depth
- the number of arrays. (Default 7)decay
- the probability of reducing a counter in an occupied bucket. It is raised to power of it's counter (decay ^ bucket[i].counter). Therefore, as the counter gets higher, the chance of a reduction is being reduced. (Default 0.9)
