Elassandra vs Transwarp Hyperbase

Elassandra combines Apache Cassandra’s distributed storage with embedded OpenSearch search on each node. Its maintained line targets Apache Cassandra 4.0.x, OpenSearch 1.3.x, and Java 11. OpenSearch indices map to Cassandra keyspaces, documents to rows, and indexed fields to columns or cells; the current _doc model maps to a Cassandra table. Cassandra remains the durable layer, allowing restart recovery to replay Cassandra state and rebuild a local search view. Applications can search through the OpenSearch HTTP API or CQL, with HTTP responses following OpenSearch style. Data placement uses Cassandra token ownership, while replicas follow keyspace replication. Schemas can be created from OpenSearch indexes or discovered from existing Cassandra schemas through mappings. Integrations listed include OpenSearch plugins, OpenSearch Dashboards, and Spark. Deployment options include tarball, Debian package, RPM, Docker image, and Helm chart. Elassandra is free and open source, with a 30-day trial noted.

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.
