Hi, I have an issue with OpenSearch hosted on AWS, for some reason, my index that I use for product search has disappeared twice in stage. The dev environment is completely fine.It happened first time around a month ago, and today I discovered that it disappeared again. No lifecycle policy was attached.After first error I thought about enabling audit logs, but I then got busy with another task, and even if I enable them now my understanding is that I won’t be able to see what actually happened, and I can’t wait another month for this to happen again.
OpenSearch version:
2.17.0
Environment:
- Stage: index disappeared twice (~28 days apart)
- Dev: index is fine
Index settings:
- No ISM or ILM policy
- Manually created
- Standard mappings
I am the only one who is using OpenSearch, it is also accessed by a Lambda that manages products (updated items, add new ones, etc), but it doesn’t have a feature to remove an index. Another lambda does actual product retrieval logic, but as it queries search, I don’t think it has anything to do with the issue.Are there internal mechanisms or bugs that could explain this?
How to trace deletions more reliably?
Have any ideas what I should do next?
