Releases and client availability
Server download
Section titled “Server download”The standard installer distributes a compiled server binary. Engine source is not publicly available. The documentation examples use 1.1.19-rc.12; the macOS arm64 download was checked again on October 25, 2026.
particledb --versionparticledb start --helpThat release currently prints spanner 1.1.19-rc.12. Record the version and the artifact checksum when reproducing a result. The installer’s latest download can change; it is not an immutable benchmark artifact.
The downloadable server is a release candidate. Check feature limits, transaction settings and recovery requirements before adopting it. Optional Python Particles require a separate enabled distribution and authoring package.
SDK license policy
Section titled “SDK license policy”ParticleDB-authored SDKs and the JDBC driver use MIT. Each current source package includes the MIT license. Third-party dependencies retain their own licenses.
Published ParticleDB clients
Section titled “Published ParticleDB clients”Availability checked on October 25, 2026:
| Package | Published version | License in published metadata |
|---|---|---|
| ParticleDB JDBC | 1.0.8 |
Apache-2.0 |
| ParticleDB Java SDK | 1.0.0 |
Apache-2.0 |
The Java guide documents JDBC and pgjdbc. Package publication alone does not establish compatibility with every server version.
The published Maven versions above predate the current MIT release candidates; their immutable package metadata still declares Apache-2.0. The newer native JDBC, Java, Python, Go, Rust and TypeScript SDKs are release candidates and are not yet published as a matching MIT release set. In particular, the native Python, Go, Rust and TypeScript candidates do not yet have public registry installation commands.
Other language clients
Section titled “Other language clients”The language guides identify the published libraries used in their examples, including psycopg, node-postgres, pgx and tokio-postgres. Those third-party clients have their own publishers and licenses. A language guide does not imply that a ParticleDB-branded native package is published for that language.
Benchmark releases
Section titled “Benchmark releases”A public result needs an immutable download, exact version and checksum, edition, runtime prerequisites and a matching reproduction bundle. An unpublished candidate or a later installer build does not reproduce an earlier measurement. See ClickBench methodology.
