Tencent Cloud Data Lake Compute (DLC) is a cloud service for querying data through shared or dedicated engines. It includes a metadata catalog, governance controls, and support for open table formats. Queries are available through both a graphical interface and a command-line interface. DLC lists three plans: Shared engine, Dedicated engine pay-as-you-go, and Dedicated engine subscription. Shared engine billing is based on successfully scanned query data. The dedicated engine plans use compute units, with one CU described as approximately one CPU core and 4 GB of memory. The service is paid and has no free plan. Its listed platform is web, so access is browser-based. The plan choices separate scanned-data billing from dedicated capacity, with dedicated resources available under either pay-as-you-go or subscription terms. DLC therefore combines query access with cataloging and governance in a cloud deployment.
