Apache Drill vs Kubling

Apache Drill is a schema-free SQL query engine for Hadoop, NoSQL databases, and cloud storage. It can query raw data where it resides without first loading it, defining schemas, or transforming it. Its JSON data model supports complex and nested structures, and a single query can join data across multiple datastores. Listed sources include HBase, MongoDB, HDFS, Amazon S3, Azure Blob Storage, Google Cloud Storage, Swift, NAS, and local files. JDBC and ODBC drivers connect Drill to tools including Tableau, Qlik, MicroStrategy, Spotfire, SAS, and Excel; developers can also use its REST API in custom applications. Drill can run embedded on a laptop or in distributed mode on a server cluster, and the homepage lists Mac, Windows, and Linux. Documented security options include Kerberos, username and password authentication, Digest, authorization, and impersonation. The software is free under Apache License 2.0. A compatibility limit: official support for Hadoop 2 and Java 8 was dropped with Drill 1.22.0.

Kubling gives AI agents and automation a bounded model of live IT and OT state, federated directly from source systems. It defines shared entities, relationships, source ownership, and valid actions so queries and mutations can cross databases, APIs, and infrastructure. Providers translate operations into each source’s native protocol while retaining credentials, source logic, and release cycles; Kubling handles federation, planning, and policy. The OpenAPI provider exposes API operations as relational entities and maps mutations to HTTP operations. Instances can use local providers, federate other Kubling instances, or do both, with no central instance required. Providers are independent services behind a public gRPC contract and can be written in any gRPC-supported language. The catalog lists Cassandra, Kubernetes, OpenAPI, Redis, and an in-memory provider. The provider protocol, Go SDK, and official providers are open source, but the engine is not. Quickstart requires Git, Docker Engine, and Docker Compose v2. Provider APIs are pre-1.0; exact versions are recommended.
