This article provides an introduction to ReductStore and explains how to use the Reduct C++ SDK to subscribe to data from the database.

Prerequisites​

To subscribe to new records, we should use a continuous query, which has been supported by ReductStore since version v1.4. We can use the following Docker command to run it:

docker pull reduct/store:latest
docker run -p 8383:8383 reduct/store:latest

Now, we need to install the Reduct Client SDK for C++. Please refer to these instructions.

The ReductStore Project hosts the free "cats" dataset, which contains about 10K photos of cats in JPEG format with eye coordinates, a month, and ears as labels. In this example, we can learn how to download the dataset from the ReductStore instance and draw the features using the OpenCV library.

Installing Dependencies​

First, we need to install the ReductStore Client SDK for Python to download the photos and labels. We also need the OpenCV Python library for drawing features and Pillow to display images in the Jupyter environment:

pip install reduct-py opencv-python Pillow

Getting Data​

To retrieve data we need the URL of the ReductStore instance, the bucket name, where we store our datasets and an API token with read access, so that we can connect to the database by using the Client class:

from reduct import Client, Bucket

HOST = "https://play.reduct.store"
API_TOKEN = "reductstore"
BUCKET = "datasets"

client = Client(HOST, api_token=API_TOKEN)

bucket: Bucket = await client.get_bucket(BUCKET)

We are excited to announce the release of ReductStore Client SDK for C++ v1.3.0! This release includes support for the ReductStore API v1.3.0 with labels and content type.
