Variants

Create(CreateParameters)

The initial worker oplog entry

ImportedFunctionInvoked(ImportedFunctionInvokedParameters)

The worker invoked a host function

ExportedFunctionInvoked(ExportedFunctionInvokedParameters)

The worker has been invoked

ExportedFunctionCompleted(ExportedFunctionCompletedParameters)

The worker has completed an invocation

Suspend(Datetime)

Worker suspended

Error(ErrorParameters)

Worker failed

NoOp(Datetime)

Marker entry added when get-oplog-index is called from the worker, to make the jumping behavior more predictable.

Jump(JumpParameters)

The worker needs to recover up to the given target oplog index and continue running from the source oplog index from there jump is an oplog region representing that from the end of that region we want to go back to the start and ignore all recorded operations in between.

Interrupted(Datetime)

Indicates that the worker has been interrupted at this point. Only used to recompute the worker’s (cached) status, has no effect on execution.

Exited(Datetime)

Indicates that the worker has been exited using WASI’s exit function.

ChangeRetryPolicy(ChangeRetryPolicyParameters)

Overrides the worker’s retry policy

BeginAtomicRegion(Datetime)

Begins an atomic region. All oplog entries after BeginAtomicRegion are to be ignored during recovery except if there is a corresponding EndAtomicRegion entry.

EndAtomicRegion(EndAtomicRegionParameters)

Ends an atomic region. All oplog entries between the corresponding BeginAtomicRegion and this entry are to be considered during recovery, and the begin/end markers can be removed during oplog compaction.

BeginRemoteWrite(Datetime)

Begins a remote write operation. Only used when idempotence mode is off. In this case each remote write must be surrounded by a BeginRemoteWrite and EndRemoteWrite log pair and unfinished remote writes cannot be recovered.

EndRemoteWrite(EndRemoteWriteParameters)

Marks the end of a remote write operation. Only used when idempotence mode is off.

PendingWorkerInvocation(PendingWorkerInvocationParameters)

An invocation request arrived while the worker was busy

PendingUpdate(PendingUpdateParameters)

An update request arrived and will be applied as soon the worker restarts

SuccessfulUpdate(SuccessfulUpdateParameters)

An update was successfully applied

FailedUpdate(FailedUpdateParameters)

An update failed to be applied

GrowMemory(GrowMemoryParameters)

Increased total linear memory size

CreateResource(CreateResourceParameters)

Created a resource instance

DropResource(DropResourceParameters)

Dropped a resource instance

Log(LogParameters)

The worker emitted a log message

Restart(Datetime)

The worker’s has been restarted, forgetting all its history

ActivatePlugin(ActivatePluginParameters)

Activates a plugin

DeactivatePlugin(DeactivatePluginParameters)

Deactivates a plugin

Revert(RevertParameters)

Revert a worker to a previous state

CancelInvocation(CancelInvocationParameters)

Cancel a pending invocation

StartSpan(StartSpanParameters)

Start a new span in the invocation context

FinishSpan(FinishSpanParameters)

Finish an open span in the invocation context

SetSpanAttribute(SetSpanAttributeParameters)

Set an attribute on an open span in the invocation context

ChangePersistenceLevel(ChangePersistenceLevelParameters)

Change the current persistence level
