Microsoft Azure Cosmos DB and ClickHouse are prominent contenders in the highly scalable database category. Microsoft Azure Cosmos DB has the advantage due to its extensive API support and multimodal capabilities, despite being more expensive than ClickHouse.
Features: Microsoft Azure Cosmos DB offers a highly scalable NoSQL database with document, key-value, and graph data models. Its flexibility, ease of integration, and extensive API support, especially for IoT and real-time analytics, are notable. It also features automatic scaling. ClickHouse stands out for its speed and efficiency in real-time data analysis and handling large volumes with advanced compression, making it a cost-effective choice for high-speed data tasks.
Room for Improvement: Microsoft Azure Cosmos DB users face challenges with pricing complexity, integration needs, and a steep learning curve. Improvements in documentation, multi-collection joins, and analytical capabilities are sought. ClickHouse needs to enhance documentation, SQL syntax compatibility, and integration with third-party tools. Its transactional capabilities are limited for high-volume small writes.
Ease of Deployment and Customer Service: Microsoft Azure Cosmos DB is primarily deployed in public clouds with robust Azure integration and comprehensive technical support, although users note slow response times in the support process. ClickHouse is appreciated for its straightforward self-hosting in on-premises and hybrid setups, with quicker support experiences.
Pricing and ROI: Microsoft Azure Cosmos DB operates on a complex pay-as-you-go model based on consumption, often considered expensive for smaller operations but noted for cost savings upon optimization. ClickHouse offers a low-cost open-source model, particularly appealing in self-hosted environments for those with the expertise to manage it efficiently.
