Native workgroup
Tachyon ISAM with classic status codes. Wire family TCP 1583. Files are unencumbered .spv / .cmm.
Compatibility
VeloceDB is the database. Applications do not sit on MySQL or SQL Server underneath it. You install a workgroup engine, then connect with ODBC, JDBC, or the CLI — plus optional PostgreSQL beside it.

| Engine | Surface | Port | Files |
|---|---|---|---|
| Workgroup ISAM | Tachyon keyed records + status surface | TCP 1583 | .spv / .cmm |
| Relational SQL | SELECT / JOIN / DDL / TX | TCP 2143 | CMM catalog |
| PostgreSQL sidecar | Optional checkpoints / pgvector | 5432 + pooler :6432 | external |
Tachyon ISAM with classic status codes. Wire family TCP 1583. Files are unencumbered .spv / .cmm.
ODBC, JDBC, and the veloce CLI on TCP 2143. Dialect covers SELECT, JOIN, DDL, and transactions.
Checkpoints and pgvector can ride a Postgres sidecar. The workgroup engine does not require Postgres, MySQL, Oracle, or SQL Server to run.
