 Duration timeout)

Method Details

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 interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list where item is added, must not be null

item - the item to add, must not be null

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. This allows dynamic heavy-hitter detection of items being entered or expelled from Top-K list. Group: top-k

Specified by:

topkAdd in interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list where item is added, must not be null

items - the items to add, must not be null, must not be empty, must not contain null

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:

topkIncrBy in interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list where item is added, must not be null

item - the item to add, must not be null

increment - increment to current item score. Increment must be greater or equal to 1. Increment is limited to 100,000 to avoid server freeze.

topkIncrBy

public void topkIncrBy(K key,
 Map<V,Integer> couples)

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:

topkIncrBy in interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list where item is added, must not be null

couples - The map containing the item / increment, must not be null, must not be empty

topkList

public void topkList(K key)

Description copied from interface: TransactionalTopKCommands

Execute the command TOPK.LIST. Summary: Return full list of items in Top K list. Group: top-k

Specified by:

topkList in interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list, must not be null

topkListWithCount

public void topkListWithCount(K key)

Description copied from interface: TransactionalTopKCommands

Execute the command TOPK.LIST. Summary: Return full list of items in Top K list. Group: top-k

Specified by:

topkListWithCount in interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list, must not be null

topkQuery

public void topkQuery(K key,
 V item)

Description copied from interface: TransactionalTopKCommands

Execute the command TOPK.QUERY. Summary: Checks whether an item is one of Top-K items. Multiple items can be checked at once. Group: top-k

Specified by:

topkQuery in interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list, must not be null

item - the item to check, must not be null

topkQuery

public void topkQuery(K key,
 V... items)

Description copied from interface: TransactionalTopKCommands

topkReserve

public void topkReserve(K key,
 int topk)

Description copied from interface: TransactionalTopKCommands

Execute the command TOPK.RESERVE. Summary: Initializes a TopK with specified parameters. Group: top-k

Specified by:

topkReserve in interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list, must not be null

topk - the number of top occurring items to keep.

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 interface TransactionalTopKCommands<K,V>

Parameters:

key - the name of list, must not be null

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)
