Package io.quarkus.redis.datasource.bloom

Interface ReactiveBloomCommands<K,V>

Type Parameters:

K - the type of the key

V - the type of the value stored in the filter

All Superinterfaces:

ReactiveRedisCommands

All Known Implementing Classes:

ReactiveBloomCommandsImpl

public interface ReactiveBloomCommands<K,V>
extends ReactiveRedisCommands

Allows executing commands from the bloom group. These commands require the Redis Bloom module to be installed in the Redis server.

See the bloom command list for further information about these commands.

Method Detail

bfadd

io.smallrye.mutiny.Uni<Boolean> bfadd(K key,
                                      V value)

Execute the command BF.ADD. Summary: Adds the specified element to the specified Bloom filter. Group: bloom

If the bloom filter does not exist, it creates a new one.

Parameters:

key - the key

value - the value, must not be null

Returns:

a uni producing true if the value did not exist in the filter, false otherwise.

bfexists

io.smallrye.mutiny.Uni<Boolean> bfexists(K key,
                                         V value)

Execute the command BF.EXISTS. Summary: Determines whether an item may exist in the Bloom Filter or not. Group: bloom

Parameters:

key - the key

value - the value, must not be null

Returns:

a uni producing true if the value may exist in the filter, false means it does not exist in the filter.

bfmadd

io.smallrye.mutiny.Uni<List<Boolean>> bfmadd(K key,
                                             V... values)

Execute the command BF.MADD. Summary: Adds one or more items to the Bloom Filter and creates the filter if it does not exist yet. This command operates identically to BF.ADD except that it allows multiple inputs and returns multiple values. Group: bloom

Parameters:

key - the key

values - the values, must not be null, must not contain null, must not be empty.

Returns:

a uni producing a list of booleans. true if the corresponding value did not exist in the filter, false otherwise.

bfmexists

io.smallrye.mutiny.Uni<List<Boolean>> bfmexists(K key,
                                                V... values)

Execute the command BF.MEXISTS. Summary: Determines if one or more items may exist in the filter or not. Group: bloom

Parameters:

key - the key

values - the values, must not be null, must not contain null, must not be empty.

Returns:

a uni producing a list of booleans. true if the corresponding value may exist in the filter, false does not exist in the filter.

bfreserve

io.smallrye.mutiny.Uni<Void> bfreserve(K key,
                                       double errorRate,
                                       long capacity)

Execute the command BF.RESERVE. Summary: Creates an empty Bloom Filter with a single sub-filter for the initial capacity requested and with an upper bound error_rate. Group: bloom

Parameters:

key - the key

errorRate - The desired probability for false positives. The rate is a decimal value between 0 and 1.

capacity - The number of entries intended to be added to the filter.

Returns:

a uni producing null when the operation completes

bfreserve

io.smallrye.mutiny.Uni<Void> bfreserve(K key,
                                       double errorRate,
                                       long capacity,
                                       BfReserveArgs args)

Execute the command BF.RESERVE. Summary: Creates an empty Bloom Filter with a single sub-filter for the initial capacity requested and with an upper bound error_rate. Group: bloom

Parameters:

key - the key

errorRate - The desired probability for false positives. The rate is a decimal value between 0 and 1.

capacity - The number of entries intended to be added to the filter.

args - the extra parameters

Returns:

a uni producing null when the operation completes

bfinsert

io.smallrye.mutiny.Uni<List<Boolean>> bfinsert(K key,
                                               BfInsertArgs args,
                                               V... values)

Execute the command BF.INSERT. Summary: BF.INSERT is a sugarcoated combination of BF.RESERVE and BF.ADD. It creates a new filter if the key does not exist using the relevant arguments. Next, all ITEMS are inserted. Group: bloom

Parameters:

key - the key

args - the creation parameters

values - the value to add, must not contain null, must not be null, must not be empty

Returns:

a uni producing a list of booleans. true if the corresponding value may exist in the filter, false does not exist in the filter.
