Baidu Tera vs Transwarp Hyperbase

Baidu Tera is a free, self-hosted distributed NoSQL database for real-time applications. It stores sparse, multidimensional tables indexed by row key, column key and timestamp, with the project describing scale to petabytes across thousands of commodity servers. Tera supports strict consistency, MVCC, automatic failover, online schema changes and snapshots. Configurable automatic sharding can use ranged or hashed strategies, with linear and modular scalability. Storage options include RAMDISK, SSD and disk tables, plus tiered and block caches and Bloom Filters for real-time queries. Applications can connect through C++, Java, Python and REST APIs. Its architecture includes an SDK, master and tablet servers using an enhanced LevelDB engine. Deployment can use raw machines or Docker, with pseudo-distributed operation on one host. The repository lists BSD-3-Clause and Apache-2.0 licenses.

Transwarp Hyperbase is a self-hosted NoSQL wide-table database for real-time, low-latency access under high concurrency. It supports precise and range queries, stream-processing applications, full-text search and retrieval of unstructured data. Stored content can include structured records, text, images, videos and objects. Distributed full-text indexing through Transwarp Scope supports global, local and high-dimensional indexes, advanced filters and automatic index selection. Hyperbase accepts ANSI SQL 2003 syntax and is compatible with open-source HBase. Transwarp says it supports concurrent queries for millions of users and high-volume insert, modify and delete operations. SQL Bulkload handles data migration, while DSTool provides one-click cluster repair. Transwarp Guardian adds authentication, table access controls and multi-tenancy permissions. The database runs on general server clusters and is listed as part of the TDH data platform. It is available through an API. Pricing is by inquiry, with no public price listed.
