Cloudera Data Lake Service vs Tencent Cloud Data Lake Compute (DLC)

Cloudera Data Lake Service provides data governance, metadata management, access controls, and auditing for data lake workloads. It captures schema and metadata definitions that platform workloads discover or create, then supports search, lineage, chain-of-custody auditing, classification, profiling, and a business glossary. Security capabilities include role- and attribute-based policies, auditing of unauthorized access, and encryption at rest and in motion with key management. Apache Ranger can apply access policies at database, table, column, and file levels, including dynamic conditions such as time or geolocation. Apache Knox provides a protected single sign-on gateway to Data Lake and Cloudera Data Platform interfaces. A cluster includes Hive Metastore, Ranger, Atlas, and Knox. Cloudera supports light-duty and enterprise Data Lakes on AWS, Azure, and GCP. Listed capabilities also include SQL analytics, streaming ingestion, data sharing, and open table formats. The service has web and API access and supports hybrid deployment. The listed pricing note starts at $0.20, while the plan is also described as Contact Sales for pricing; cloud prices exclude infrastructure and networking costs.

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.
