OpenSearch Indexes

When building a new environment or the search indexes are deleted and needs to be rebuilt, make sure to run the InitHandler.

How to re-index

If the index already exists, and it is not necessary to update mappings, skip to step 3.

1. Trigger DeleteNviCandidateIndexHandler. Verify that the index is deleted.
2. Trigger InitHandler. Verify that the index is created.
3. Trigger NviBatchScanStartHandler with input:

{
  "types": [
    "CANDIDATE"
  ]
}

How to requeue candidates in IndexDLQ

The IndexDLQ is a shared DLQ for all handlers related to indexing. NviRequeueDlqHandler consumes messages from the IndexDLQ, and updates the candidate in the DB with a new version. This will trigger the indexing flow for the candidates.

Default count (number of messages consumed from DLQ) is 10. To specify another count, provide it as input:

{
  "count": 100
}

DLQ Redrives

See template for which DLQs are available for redrive (configured with RedrivePolicy). To start a DLQ redrive, locate the DLQ in the AWS console (SQS) and press Start DLQ Redrive.
