Huemul BigDataGovernance, es una framework que trabaja sobre Spark, Hive y HDFS. Permite la implementación de una estrategia corporativa de dato único, basada en buenas prácticas de Gobierno de Datos. Permite implementar tablas con control de Primary Key y Foreing Key al insertar y actualizar datos utilizando la librería, Validación de nulos, largos de textos, máximos/mínimos de números y fechas, valores únicos y valores por default. También permite clasificar los campos en aplicabilidad de derechos ARCO para facilitar la implementación de leyes de protección de datos tipo GDPR, identificar los niveles de seguridad y si se está aplicando algún tipo de encriptación. Adicionalmente permite agregar reglas de validación más complejas sobre la misma tabla.

Status of the Project

TensorBase hasn't been updated for a while. Thanks for all friends' concern and inquiries, we reply as follows:

TensorBase hopes the open source not become a copy game. TensorBase has a clear-cut opposition to fork communities, repeat wheels, or hack traffics for so-called reputations (like Github stars). After thoughts, we decided to temporarily leave the general data warehousing field.

Here, let's recap all the world's first of TensorBase:

  1. The world's first ClickHouse compatible open-source implementation.
  2. 2x faster write throughput than that of ClickHouse (based on our bug fixed Rust client, you can get ~1.7x speedup by our another simple concurrent script here).
  3. Faster query speed in the simple aggregation than that of ClickHouse(benchmarked against ClickHouse 2021.6).
  4. First no-LSM, write and read optimized storage layer proposed.
  5. First make "copy-free, lock-free, async-free, dyn-free" happened in an open-source DBMS's critical path.
  6. First DBMS running on the real-world RISC-V hardware.
  7. First top-performance whole-lifecycle JIT SQL query engine(not completely open sourced, but we release the initial prototype in the network which you can try, and more you can get the ideas from the blogs, presentations and videos.)...

For people looking for production level data warehouse solution, we still recommend ClickHouse. We wish that ClickHouse can learn from these work and evolve itself to better.

For people who want to learn how a database system can be built up, or how to apply modern Rust to the high performance field, or embed a lightweight data analysis system into your own big one. You can still try, ask or contribute to TensorBase. The committers are still around the community. We will help you in all kinds of interesting things pursued in the project by us and maybe you. We still maintain the project to look forward to meeting more database geniuses in this world, although no new feature will be added in the near future.

The core team of TensorBase has moved to another new type of domain-specific database. We are hiring!

What is TensorBase

TensorBase is a new big data warehousing with modern efforts.

TensorBase is building on top of Rust, Apache Arrow and Arrow DataFusion.

TensorBase hopes to change the status quo of bigdata system as follows:

  • low efficiency (in the name of 'scalable')
  • hard to use (for end users) and understand (for developers)
  • not evolving with modern infrastructures (OS, hardware, engineering...)


  • Out-of-the-box to play ( get started just now )
  • Lighting fast architectural performance in Rust ( real-world benchmarks )
  • Modern redesigned columnar storage
  • Top performance network transport server
  • ClickHouse compatible syntax
  • Green installation with DBA-Free ops
  • Reliability and high availability (WIP)
  • Cluster (WIP)
  • Cloud-Native Adaptation (WIP)
  • Arrow dataLake (...)

Architecture (in 10,000 meters altitude)


Quick Start



TensorBase is lighting fast. TensorBase has shown better performance than that of ClickHouse in simple aggregation query on 1.47-billion rows NYC Taxi Dataset.

TensorBase has enabled full workflow for TPC-H benchmarks from data ingestion to query.
