FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Bloom Filter
A Bloom filter is a space-efficient probabilistic data structure designed to determine whether an element is present in a set. False positives are possible.
reserve
BloomFilter::reserve(string $key, float $error, int $capacity): bool
Creates an empty Bloom Filter with a given desired error ratio and initial capacity.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfreserve.
insert
BloomFilter::insert(string $key, string $value, ?float $error = null, ?int $capacity = null): bool
Adds an item to the Bloom Filter, creating the filter if it does not yet exist.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfadd and https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfinsert.
insertMany
BloomFilter::insertMany(string $key, array $values, ?float $error = null, ?int $capacity = null): bool[]
Adds several items to the BloomFilter, creating the filter if it does not yet exist.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfmadd and https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfinsert.
insertIfKeyExists
BloomFilter::insertIfKeyExists(string $key, string $value): bool
Adds an item to the Bloom Filter, only if the filter already exists.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfadd and https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfinsert.
insertManyIfKeyExists
BloomFilter::insertManyIfKeyExists(string $key, array $values): bool[]
Adds several items to the Bloom Filter, only if the filter already exists.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfadd and https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfinsert.
exists
BloomFilter::exists(string $key, string $value): bool
Checks if an item exists.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfadd.
manyExist
BloomFilter::manyExist(string $key, array $values): bool[]
Checks if many items exist.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfmexists.
scanDump, loadChunks and copy
BloomFilter::scanDump(string $key): array
BloomFilter::loadChunks(string $key, array $chunks): void
BloomFilter::copy(string $sourceKey, string $destKey): void
scanDump exports the whole Bloom Filter in an array, which can be loaded in chunks by
loadChunks. The copy function, using the previous 2 functions, allows to quickly
copy one Bloom Filter to a different key.
See https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfscandump and https://oss.redislabs.com/redisbloom/Bloom_Commands/#bfloadchunk.
Cuckoo Filter
Cuckoo filter is similar to Bloom Filter, but it's even more space-efficient and allows deleting items.
reserve
CuckooFilter::reserve(string $key, int $capacity, ?int $bucketSize = null, ?int $maxIterations = null, ?int $expansion = null): bool
Create an empty cuckoo filter with an initial capacity. The false positive rate is fixed at about 3%, depending on how full the filter is.
See https://oss.redislabs.com/redisbloom/Cuckoo_Commands/#cfreserve.
insert
CuckooFilter::insert(string $key, string $value, bool $allowDuplicateValues = true, ?int $capacity = null): bool
Adds an item to the cuckoo filter, creating the filter if it does not exist.
See https://oss.redislabs.com/redisbloom/Cuckoo_Commands/#cfadd, https://oss.redislabs.com/redisbloom/Cuckoo_Commands/#cfaddnx, https://oss.redislabs.com/redisbloom/Cuckoo_Commands/#cfinsert, https://oss.redislabs.com/redisbloom/Cuckoo_Commands/#cfinsertnx.
insertMany
CuckooFilter::insertMany(string $key, array $values, bool $allowDuplicateValues = true, ?int $capacity = null): bool[]
Similar to the previous, adds many values to the key.

insertIfKeyExists
CuckooFilter::insertIfKeyExists(string $key, string $value, bool $allowDuplicateValues = true, ?int $capacity = null): bool
Inserts an item in a cuckoo filter, only if it exists.

insertManyIfKeyExists
CuckooFilter::insertManyIfKeyExists(string $key, array $values, bool $allowDuplicateValues = true, ?int $capacity = null): bool[]
Inserts many items in a cuckoo filter, only if it exists.

CountMinSketch
Count-Min Sketch is a probabilistic data structure that serves as a frequency table of events in a stream of data.
initByDimensions
CountMinSketch::initByDimensions(string $key, int $width, int $depth): bool
Initializes a CountMinSketch named $key with the $width and $depth provided by the user.
See https://oss.redislabs.com/redisbloom/CountMinSketch_Commands/#cmsinitbydim.
initByProbability
CountMinSketch::initByProbability(string $key, float $error, float $probability): bool
Initializes a CountMinSketch to accommodate the desired error rate and probability for inflated count.
See https://oss.redislabs.com/redisbloom/CountMinSketch_Commands/#cmsinitbyprob.
incrementBy
CountMinSketch::incrementBy(string $key, Pair ...$pairs): bool
Increments one or more items by a given value in a CountMinSketch. A Pair represents an item and the value we want to increment.
See https://oss.redislabs.com/redisbloom/CountMinSketch_Commands/#cmsincrby.
query
CountMinSketch::query(string $key, string ... $items): Pair[]
Returns the approximate count for one or more items.
See https://oss.redislabs.com/redisbloom/CountMinSketch_Commands/#cmsquery.
merge
Merges multiple CountMinSketches into one, so that the value for each item is the sum
of the values in each sketch. The $sourceKeysWeightMap is an associative array
where each key is a sketch, and the value is the weight, that is the value we want
each item count to be multiplied by before merging.
CountMinSketch::merge(string $destinationKey, array $sourceKeysWeightMap) : bool
See https://oss.redislabs.com/redisbloom/CountMinSketch_Commands/#cmsmerge.
info
Returns an instance of CountMinSketchInfo, which contains information regarding width, depth and total count of the sketch.
CountMinSketch::info(string $key): CountMinSketchInfo
See https://oss.redislabs.com/redisbloom/CountMinSketch_Commands/#cmsinfo.
TopK
Similar to CountMinSketch, is based on the algorithm described here: https://www.usenix.org/conference/atc18/presentation/gong
reserve
TopK::reserve(string $key, int $topK, int $width, int $depth, float $decay): bool
Reserves a TopK suitable to calculate $topK top elements, with a given $width and $depth and with
a specified $decay (probability of reducing a counter in an occupied bucket).
See https://oss.redislabs.com/redisbloom/TopK_Commands/#topkreserve.
add
Adds one or more item to the TooK. If an item enters the Top-K list, the item which is expelled is returned in the position that was occupied by the added item that took its place in the Top-K.
TopK::add(string $key, string ... $items): array
See https://oss.redislabs.com/redisbloom/TopK_Commands/#topkadd.
incrementBy
Increase the score of an item in the data structure by increment. Similar to add, expelled items are returned.

See https://oss.redislabs.com/redisbloom/TopK_Commands/#topkquery.
count
Returns a subset of $items containing the elements found in the top-k with their approximate count.

See https://oss.redislabs.com/redisbloom/TopK_Commands/#topkcount.
list
Returns the top-k items with their relative position.

See https://oss.redislabs.com/redisbloom/TopK_Commands/#topklist.
info
Returns a TopKInfo object containing information about size, with, depth and decay of the Top-K
