This update includes bug fixes:
Fixes this issue. An app returning a non-2xx status code from a timer invocation would cause a periodic timer to no longer trigger.
An Actor app which restarted/crashed, or was otherwise busy, would cause a timer to no longer trigger. This breaks backwards compatibility where a periodic Actor timer would continue to trigger at the defined period, even if the actor was busy or had an error.
The Actor timer handle logic deactivates the timer if any timer invocation failed. Regardless of whether the timer had further ticks defined in it's period schedule.
As did before v1.15.0, treat any successful or failed timer invocation as the same, and tick the Actor timer forward allowing for future invocations.
Fixes an issue where Daprd would continually grow in memory when using Workflows.
Daprd would eventually use all available memory on the node or cgroup, causing an OOM crash.
An internal Actor lock object was not being released from Workflow Activities.
Release lock memory during Workflow Activity completion.
Scheduler would continuously grow in memory when under heavy usage, for example using Workflows.
Scheduler would eventually use all available memory on the node or cgroup, causing an OOM crash.
Etcd does not automatically Defragment after compaction, causing unused memory to not be released.
Every 10 minutes, each Scheduler host will check whether the total memory is twice the size of used memory and if so, will defragment that host's Etcd database.
