Datapankin

Datapankin is an open-source distributed data platform designed to store, manage, and analyze large-scale datasets. It combines a scalable storage layer with a distributed compute engine and a metadata catalog, enabling interactive SQL-like queries, batch processing, and streaming ingestion through pluggable connectors. The project emphasizes data locality, reproducible pipelines, and pluggable security at rest and in transit.

Datapankin originated as a community-driven project in the mid-2010s, with initial releases in 2016 under a permissive license. Over successive releases, the architecture matured to support multi-tenant deployments, schema evolution, and time-travel queries.

Core components include a storage layer using a columnar format, a distributed query planner and executor, a metadata store backed by a raft-based consensus service, and a data catalog with lineage tracking. Data is partitioned into shards and replicated to ensure fault-tolerance, with end-to-end encryption and role-based access control.

Datapankin supports data warehousing workloads, ad hoc analytics, and machine-learning pipelines. It offers schema evolution, data versioning, and time-travel, as well as connectors to popular messaging systems and file formats. It provides APIs in SQL, Python, and REST, and integrates with notebooks and orchestration tools.

Adoption has been strongest in academic and research environments, government pilots, and some mid-size enterprises seeking an open architecture for large datasets. Critics cite operational complexity, resource requirements, and the need for governance to manage data access across tenants.
