MatrixOne, an open source HTAP database that speaks the MySQL wire protocol, with vector and fulltext search built in.
MatrixOne is an open source hyperconverged database that handles transactional and analytical work in a single engine, so the same system that records rows can also answer aggregate queries over them without a separate warehouse and without a pipeline to copy data between the two. It speaks the MySQL wire protocol, so existing MySQL clients, drivers and tools connect to it unchanged and familiar SQL works as written.
Alongside ordinary relational tables it offers native vector columns with distance functions for similarity search, and fulltext indexing with match queries for keyword search, which lets one database back semantic retrieval, keyword lookup and conventional reporting at the same time. It suits teams who want transactional and analytical workloads served together, developers building retrieval and search features who would rather not run a separate vector store, and anyone who wants a MySQL compatible engine they run on infrastructure they control.
cloudimg delivers MatrixOne fully installed as a standalone single node engine, so the database accepts connections shortly after the instance boots with nothing to assemble. The image is secure by default in an unusually strict sense: upstream ships two built in accounts that both use a well known published password, and rather than change them after the fact this image bootstraps the catalogue with a password generated uniquely on each instance's first boot, so the published credential never exists on your instance at all, and first boot refuses to complete if it does. Credentials are written to a root only file and the database port is closed at the network layer by default. Database storage sits on a dedicated disk separate from the operating system, memory limits adapt to whatever instance size you run, the base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step deploy guide and backed by 24/7 cloudimg support.
