Answered from the vendors’ own pages
MariaDB: Is MariaDB completely free and open source?
Yes. MariaDB Server is licensed under GPLv2 and guaranteed to remain perpetually free and open source, independent of any commercial entities.
SourceVespa: Is Vespa open-source?
Yes, Vespa is open-source under the Apache 2.0 license. The code is available on GitHub, and you can self-host or use the managed cloud service.
SourceMariaDB: Is MariaDB backward compatible with MySQL?
Yes. MariaDB was designed as a drop-in replacement for MySQL. Every application, driver, and configuration that worked with MySQL works with MariaDB without code changes.
SourceVespa: What latency can Vespa achieve?
Vespa is designed for sub-100 millisecond latencies with thousands of queries per second, suitable for real-time search and recommendation applications.
SourceMariaDB: What are the storage engine options in MariaDB?
MariaDB supports multiple storage engines including InnoDB (transactional, default), Aria (crash-safe, good for read-heavy workloads), and MyISAM. The Aria engine is faster than InnoDB for certain read-heavy queries and full table scans.
SourceVespa: Does Vespa support vector search?
Yes, Vespa provides native vector search capabilities alongside text, structured data, and tensor operations for building comprehensive search and AI applications.
SourceMariaDB: How much does MariaDB cost?
MariaDB Community Server is completely free to download and use. MariaDB offers paid enterprise support and managed cloud services for organizations needing professional support.
SourceVespa: What is the pricing model for Vespa Cloud?
Vespa Cloud pricing is not publicly listed and requires contacting their sales team to discuss your specific use case and scale requirements.
SourceMariaDB: Does MariaDB support native JSON storage?
MariaDB stores JSON using text fields (the JSON type is an alias for LONGTEXT), not as a native binary type like MySQL does. JSON support exists but is less sophisticated than MySQL's JSON functions and syntax.
SourceMariaDB: What scaling options does MariaDB provide?
MariaDB supports both scaling up (more cores, memory, storage) and scaling out (read replication, Galera Cluster with multi-node replication). However, Galera Cluster performance cannot exceed the slowest node in the cluster.
