At QuestDB we are all about performance. To showcase querying capabilities of the database we have been running a live demo of historical taxi rides in NYC with 1.6 billion rows [1] and a geospatial dataset that contains the locations of 250k unique ships [2] moving over time. You can analyze this dataset with SQL on our live instance and see how fast each query is processed. Today, we introduce a new dataset on the same demo instance: crypto market data ingested in real-time from the Coinbase Exchange. For ingestion, we use a convenient Python library Cryptofeed, a cryptocurrency exchange feed handler that supports QuestDB. And for visualization, we use Grafana to create interactive live charts, which refresh every 5 seconds.
