Ingesting Financial Tick Data Using a Time-Series Database

QuestDB is an open-source, high-performance database tailored for market data, particularly crypto market data, offering excellent ingestion throughput, SQL analytics, and hardware efficiency. The tutorial outlines three methods for ingesting crypto market data into QuestDB: using the Cryptofeed library for easy integration with various exchanges, building a custom data pipeline for unsupported exchanges or more control over data, and employing Change Data Capture (CDC) for streaming data from external sources like Kafka. Cryptofeed simplifies data ingestion with its preconfigured integrations, but custom pipelines allow for greater customization and preprocessing, using the InfluxDB Line Protocol via QuestDB's Python SDK. CDC is highlighted as an efficient method for integrating existing data feeds from sources such as Kafka, minimizing infrastructure burden.
