redisbloom-py is a package that gives developers easy access to several probabilistic data structures. The package extends [redis-py](https://github.com/andymccurdy/redis-py)'s interface with RedisBloom's API.

### Installation
```
$ pip install redisbloom
```

### Usage example

```python
# Using Bloom Filter
from redisbloom.client import Client
rb = Client()
rb.bfCreate('bloom', 0.01, 1000)
rb.bfAdd('bloom', 'foo')        # returns 1
rb.bfAdd('bloom', 'foo')        # returns 0
rb.bfExists('bloom', 'foo')     # returns 1
rb.bfExists('bloom', 'noexist') # returns 0

# Using Cuckoo Filter
from redisbloom.client import Client
rb = Client()
rb.cfCreate('cuckoo', 1000)
rb.cfAdd('cuckoo', 'filter')        # returns 1
rb.cfAddNX('cuckoo', 'filter')      # returns 0
rb.cfExists('cuckoo', 'filter')     # returns 1
rb.cfExists('cuckoo', 'noexist')    # returns 0

# Using Count-Min Sketch
from redisbloom.client import Client
rb = Client()
rb.cmsInitByDim('dim', 1000, 5)
rb.cmsIncrBy('dim', ['foo'], [5])
rb.cmsIncrBy('dim', ['foo', 'bar'], [5, 15])
rb.cmsQuery('dim', 'foo', 'bar')    # returns [10, 15]

# Using Top-K
from redisbloom.client import Client
rb = Client()
rb.topkReserve('topk', 3, 20, 3, 0.9)
rb.topkAdd('topk', 'A', 'B', 'C', 'D', 'E', 'A', 'A', 'B',
                   'C', 'G', 'D', 'B', 'D', 'A', 'E', 'E')
rb.topkQuery('topk', 'A', 'B', 'C', 'D')    # returns [1, 1, 0, 1]
rb.topkCount('topk', 'A', 'B', 'C', 'D')    # returns [4, 3, 2, 3]
rb.topkList('topk')                         # returns ['A', 'B', 'E']
rb.topkListWithCount('topk')                # returns ['A', 4, 'B', 3, 'E', 3]
```

### Development

1. Create a virtualenv to manage your python dependencies, and ensure it's active.
   ```virtualenv -v venv```
2. Install [pypoetry](https://python-poetry.org/) to manage your dependencies.
   ```pip install poetry```
3. Install dependencies.
   ```poetry install```

[tox](https://tox.readthedocs.io/en/latest/) runs all tests as its default target. Running *tox* by itself will run unit tests. Ensure you have a running redis, with the module loaded.
