SOFA MOSN v0.6.0 released, the main changes are as follows:
i. Listener supported idle connection timeout closed configuration
ii. Log new Alertf Interface
iii. SDS supported way to obtain a certificate
iv. Metrics statistics and output optimization
v. IO Association process optimization
vi. reconstruct back end module, the dynamic update enhance performance and reduce memory usage
vii. racer module implements reconstruction, extension mechanisms to support better
New Features
- Add "connection_idle_timeout" field to Listener config, default 90s. Mosn will close idle connections when timeout.
- New function "Alertf" in ErrorLogger
- Support getting certificates from SDS mode
Refactor
- Refactor the upstream package
- Refactor the inner cluster structure
- UpdateHost does full update every time, instead of incremental update
- Refactor the snapshot implementation
- Optimize memory usage
- Some functions parameters are changed
- Refactor tracing implementation
Performance Optimize
- Optimize connection metrics
- Optimize metrics prometheus output format
- Optimize network IO
Bug Fix
- Fix panic when creating logger concurrently
- Fix panic when doing response and timeout simultaneously
- Fix http handle reset stream bug
- Fix log file cannot rotate when log file is deleted
- Fix http2 goway bug
- Fix http handle non-persistent connection bug
SOFAMosn Profile
MOSN (Modular Observable Smart Network), is a use of GoLang Service Mesh data plane development agency, function and positioning similar Envoy , aimed at providing a distributed, modular, observation, intelligent agent capabilities. MOSN support Envoy and Istio the API, you can integrate and Istio in SOFAMesh , we use MOSN alternative Envoy. MOSN contributed by hand in the initial version of ants gold dress and big entertainment Ali UC Division, expect the community to participate in a follow-up to develop and build an open source project quality.
