Saw an announcement about Apache StreamPipes Edge. Lightweight stream processing, supposedly runs on 512MB RAM. Targeting IoT but IMO relevant to low-end hosting for log aggregation and monitoring.
Key points from what I read:
- Java-based but claims "minimal footprint"
- REST API for configuration
- Docker compose available
YMMV on the Java part. Take it with a grain of salt, my experience with Java on 1GB VPS has been mixed.
Anyone actually tried this? Resource claims seem optimistic for our use case.
