Coralogix and DataDog are two prominent observability providers with distinct approaches to long-term log storage, focusing on cost-efficiency and querying capabilities. Coralogix offers significant cost savings and rapid support, claiming a competitive edge over DataDog. Its Remote Query feature allows users to query archived data without the need for reindexing, supporting both schema on read and schema on write for optimal data exploration and insight generation. In contrast, DataDog's Flex Logs enables users to store logs in their own cloud storage, such as S3, but incurs compute costs for querying archived logs. This fundamental difference highlights Coralogix's ability to offer cost-effective and efficient data discovery, allowing users to generate new insights without the overhead of reindexing, while DataDog requires reindexing, adding to the operational costs.
