Parser
This component is in charge of parsing the VAA payload and persists it.
VAA parsing is delegated to external service so that users can add custom parsers in the external service without affecting this service.
Usage
Service
parser service
Backfiller
parser backfiller [flags]
Command-line arguments
- --end-time string maximum VAA timestamp to process (default now)
- --log-level string log level (default "INFO")
- --mongo-database string mongo database
- --mongo-uri string mongo connection
- --page-size int VAA payload parser timeout (default 100)
- --start-time string minimum VAA timestamp to process (default "1970-01-01T00:00:00Z")
- --vaa-payload-parser-timeout int maximum waiting time in call to VAA payload service in second (default 10)
- --vaa-payload-parser-url string VAA payload parser service URL
Running parser as service with localstack
Here are some aws commands to configure localstack with the necessary resources
Config sns topic
aws --profile localstack --endpoint-url=http://localhost:4566 sns create-topic --name vaas-pipeline.fifo --attributes FifoTopic=true,ContentBasedDeduplication=false
Config SQS FIFO with dead letter queue localstack
aws --profile localstack --endpoint-url=http://localhost:4566 sqs create-queue --queue-name=wormhole-vaa-parser-dlq-queue.fifo --attributes "FifoQueue=true"
aws --profile localstack --endpoint-url=http://localhost:4566 sqs create-queue --queue-name=wormhole-vaa-parser-queue.fifo --attributes FifoQueue=true,MessageRetentionPeriod=3600,ReceiveMessageWaitTimeSeconds=5,VisibilityTimeout=20,RedrivePolicy="\"{\\\"deadLetterTargetArn\\\":\\\"arn:aws:sqs:us-east-1:000000000000:wormhole-vaa-parser-dlq-queue.fifo\\\",\\\"maxReceiveCount\\\":\\\"2\\\"}\""
Subscribe SQS FIFO to vaas-pipeline.fifo topic
aws --profile localstack --endpoint-url=http://localhost:4566 sns subscribe --topic-arn arn:aws:sns:us-east-1:000000000000:vaas-pipeline.fifo --protocol sqs --notification-endpoint http://localhost:4566/000000000000/wormhole-vaa-parser-queue.fifo
Check message in the dead letter queue localstack
aws --profile localstack --endpoint-url=http://localhost:4566 sqs receive-message --queue-url=http://localhost:4566/000000000000/wormhole-vaa-parser-dlq-queue.fifo
