Setting Visibility Timeout
You can configure the visibility timeout by using the
FDR_VISIBILITY_TIMEOUT configuration otpion which will
apply to all your FDR feeds.
This determines how long it takes before Humio retries an SQS message it has previously failed to ingest.
If Humio spends more time ingesting an SQS message than defined by the visibility timeout, there's a risk that Humio will read the message again and thus ingest it twice.
To avoid a duplicate ingest in this case, you can try to increase the visibility timeout up to 12 hours.
