Set redisPoolPipelineWindow to control duration before pipeline
flush (0 disables implicit pipelining) and redisPoolPipelineLimit
for max commands per pipeline (0 means no limit, only time window
applies).
Avoids the default 1 second delay when the batch doesn't
reach 100 messages within that time.
Useful when the Kafka exporter is not cached, as it would
otherwise encounter that delay. Setting BatchSize to 1
prevents this.
- made use of the test setup helpers.
- used t.Cleanup instead of defer.
- instead of waiting 50ms for the nats-server to start, used a helper
hook to attempt connections in fibonacci intervals. On success it
keeps a reference to the connection for later usage.
- handle error for stream delete function executed during cleanup.
- shorten time.Sleep durations when waiting for exports to finish.
- extract the cache itemID checking logic into a separate func
- retry failed requests in fibonacci intervals for up to 500ms
Make use of the previously added ees_success_ids and ees_failed_ids
configuration fields.
Remove Processed opts and everything related to them since they should
not be used anymore.
Fixed test compilation errors caused by the change.
Add ees_success_ids and ees_failed_ids fields in reader config. The
former will be used to set EeIDs when the event processing returns
no error, while the latter will be used otherwise (implementation
will follow).
Add config sanity checks for the added options.
They are separate for each configured reader.
Additional changes:
- rearrange config_defaults fields for ers/ees;
- add comment for RunDelay config option inside struct definition;
- improve comments for amqp opts in config_defaults.
json.UnmarshalError happens only when we pass a non-nil pointer, which
is not the case for us. Usage of go vet helps us make sure it also
won't be happening in the future
HierarchyPath parser now returns nil when
the path is empty (instead of a string slice with one
EmptyString element).
If isAbsolute is set to true, when calling the AsString
method on a nil HierarchyPath, only the separator will
be returned. Alternatively, if isAbsolute is false, it
will just return . to signal that the path currently
being processed is the one required.This avoids a nil
expr error coming from the xmlquery library.
Use the Query and QueryAll functions from the xmlquery
package to be able to handle the errors ourselves and
avoid panics.
Remove config default value for xmlRootPath. The field
will remain commented in config_defaults for reference.
Add tests for HierarchyPath.AsString function.
Add comments for XmlProvider and xmlRootPath opt.
Update XmlProvider String() func based on the comment
which specifies that it should display the already
parsed values out of cache.
Upgraded go.mod nats version due to an issue caused by version mismatch
between driver and server (uncertain).
Renamed function from getProcessOptions to getProcessedOptions.
## *NatsER.Serve
- Replaced ChanQueueSubscribe with QueueSubscribe for Core NATS consumer
to handle the message processing directly.
- Since QueueSubscribe is now used regardless of jetstream status, the
message handler has been assigned to a separate variable that can be
reused.
- The message handler is now dealing with the message processing
directly, therefore the select case listening for the channel which is
feeding NATS messages can be removed together with the channel itself
and the select. Currently, the goroutine within Serve only has to block
until the rdrExit chan is closed.
- Moved the resource check inside the handler right before starting the
message processing goroutine.
## *NatsEE.parseOpts
- Renamed function from parseOpt to parseOpts.
- Handled the error coming from GetNatsOpts function.
## *NatsEE.Connect
- Updated function to return early in case of non-nil nats.Conn value
to reduce nesting.
## *NatsEE.ExportEvent
- Use defer to release resources and RUnlock.
## *NatsEE.Close
- Use defer to Unlock.
- Update function to return early in case of nil nats.Conn value to
reduce nesting.
## ees.GetNatsOpts
- Chose switch over if else when parsing client certificate and keys
opts.
- Updated function to return the errors directly instead of assigning
them to a separate variable right before returning.
## ers.GetNatsOpts
- Chose switch over if else when parsing client certificate and keys
opts.
- Updated function to return the errors directly instead of assigning
them to a separate variable right before returning.
Removed tab from commented natsJetStreamMaxWaitProcessed option
value in config_defaults.go under ers section.
Added integration test for ERs NATS.
Updated ees/ers implementation to use the jetstream package which
separates the jetstream context from Core NATS.
Removed the jsOpts fields from the NatsEE struct. We are now using the
jetStreamMaxWait option directly through a timeout context.
Added streamName option for NATS reader since it is now required to be
specified when creating a consumer (it is not inferred based on subject
anymore).
Updated nats ers integration tests.
Updated tests to also use the new jetstream package.
Updated tests to start the nats-server using their official driver
instead of using the std go exec package. time.Sleeps are now not
required anymore to wait for the server.
In test configurations for nats readers, made sure that natsStreamName
option is populated. It is now required for consumers to know where to
subscribe.
