| Project | Description |
|---|---|
| sealdb/neosql | MySQL-kernel-based fork with enterprise features — columnar storage, HTAP |
| sealdb/neodb | Enhanced radon with distributed transactions and read/write consistency |
| sealdb/metatroni | Enhanced patroni — MySQL & PostgreSQL HA |
| sealdb/neoha | Enhanced xenon — MySQL & PostgreSQL HA, consensus via Raft and etcd |
| sealdb/sealdb | SealDB platform — unified OLTP + OLAP, storage-compute separation |
| Project | Description |
