Xbus¶
Xbus provides high-level application messaging on top of `NATS`_.
Requirements¶
Postgresql¶
Xbus uses a postgresql database 9.5+ to serialize configuration and events.
Running¶
3 binaries are created:
- xbusd: Main Xbus program.
- xbusctl: Xbus administration program (ctl = “control”); remotely connects to xbusd.
- xbus-client: Administration of actors (programs that can connect to Xbus).
Each program may be run with --help
to see available commands / flags / etc.
Warning: xbusd <xbusd> can produce a LOT of logs when placed under load. The server will crash if it is unable to write to stdio/stderr. Init systems that implement rate limitation for logs (such as systemd) may cause xbusd <xbus> to crash if the server exceeds this limit.
Updating¶
- The
migration
directory contains scripts one can use to migrate Xbus databases from one version to the other.
