This change adds a new module `opendc-experiments-workflow` that provides
provisioner implementations for experiments to use for setting up and
using the workflow engine in OpenDC.
|
|
This change updates the trace API by introducing a limited type system
for the table columns. Previously, the table columns could have any
possible type representable by the JVM. With this change, we limit the
available types to a small type system.
|
|
This change removes the OpenTelemetry integration from the OpenDC
Workflow modules. Previously, we chose to integrate OpenTelemetry to
provide a unified way to report metrics to the users.
See the previous commit removing it from the "Compute" modules for the
reasoning behind this change.

|
This change moves the trace conventions (such as table and column names)
in a separate conv package, so that it is separated from the main API.
This also allows for a potential move into a separate module in the
future.
|
|
This change updates the OpenDC codebase to use OpenTelemetry v1.11,
which stabilizes the metrics API. This stabilization brings quite a few
breaking changes, so significant changes are necessary inside the OpenDC
codebase.

|
This change removes the WorkflowSchedulerMode interface in favour of an
integrated timer scheduler approach that batches scheduling cycles over
a user-specified quantum. This quantum can be lowered to a small value
to get the interactive behavior.
There is no replacement for the random behavior, but we believe that
such a policy makes no sense in a real-world scenario.
|
|
This change adds a new module, opendc-workflow-workload that contains
helper code for constructing workflow simulations using OpenDC.
