Action Items

Owner

Look at list of CSV files that were received (as per esr.queue.csv.invalid and any others subsequent to stopping the ESR services that would have not been processed at all because the services were stopped)

Jayanta Saha Reuben Roberts Joseph (Pepe) Kelly

Review RabbitMQ esr.dlq.all messages [to identify any issues (such as?)]

Yafang Deng

Generate some Neo4J queries to check if a given {message id} was processed despite being in the DLQ

Joseph (Pepe) Kelly

Once turned-on MongoDB - check which files exported to ESR today, that they were processed before 16:11 failure

DONE Reuben Roberts

Manually resend rabbit messages for reprocessing (excluding any found in neo4j that were processed despite being in the DLQ)

Joseph (Pepe) Kelly Whilst verifying sucessful successful replay of first found that it was aready already queued.

Restart ESR services (instructions for sequencing for this are here: https://hee-nhs-tis.slack.com/archives/C01C7V5GT43/p1612957581030400 )

Consider: for the position, placement and post queues, it is possible that create+delete messages will be processed in the incorrect order. Is there a way to check this?

Work out how to retrigger file processing (as per list of CSV files to be reprocessed that will be found in S3 bucket and others that were not processed at all and were received after approx. 16:11)
