v1.5.0

Version 1.5

What's Changed

Please read before updating.

This version focuses on stability during the reconnection and introduces the dynamic send.
There are no breaking changes, but deprecations:

• BatchPublishingDelay int is not used anymore.

Dynamic send

Dynamic send improves the latency when the traffic is low; for example, with 50 msg per second, there is ~3ms latency:

go run perftest.go --rate 50 --async-send
Published     42.9 msg/s | Confirmed     42.9 msg/s |  Consumed     42.9 msg/s |  Rate Fx: 50 | Body sz: 8 | latency: 3 ms
Published     43.8 msg/s | Confirmed     43.8 msg/s |  Consumed     43.8 msg/s |  Rate Fx: 50 | Body sz: 8 | latency: 3 ms
Published     44.4 msg/s | Confirmed     44.4 msg/s |  Consumed     44.4 msg/s |  Rate Fx: 50 | Body sz: 8 | latency: 3 ms
Published     45.0 msg/s | Confirmed     45.0 msg/s |  Consumed     45.0 msg/s |  Rate Fx: 50 | Body sz: 8 | latency: 2 ms

With the 1.4.x is~ 90ms (the aggregation timeout)

go run perftest.go --rate 50 --async-send
Published     44.4 msg/s | Confirmed     44.4 msg/s |  Consumed     44.4 msg/s |  Rate Fx: 50 | Body sz: 8 | latency: 88 ms
Published     45.0 msg/s | Confirmed     45.0 msg/s |  Consumed     45.0 msg/s |  Rate Fx: 50 | Body sz: 8 | latency: 89 ms
Published     45.5 msg/s | Confirmed     45.5 msg/s |  Consumed     45.5 msg/s |  Rate Fx: 50 | Body sz: 8 | latency: 90 ms
