Noob here, how can I take an OS snapshot stored in S3 and transform it to CSV or JSON?

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

Describe the issue:
I have a OS snapshot data stored in S3, but don’t have a configured OpenSearch instance running anywhere. I’m wondering if there is any way to transform the data using lambda or by running a program on my computer locally, ideally transforming the data to csv or json and returning it to the same s3.

Snapshot data totals more than 500 GB so it is somewhat large and possibly too large to run locally. Any pointers or advice would be greatly greatly appreciated!!!

Hi @scrab,

I think it’s possible to do it by restoring the snapshot to the OpenSearch cluster and then exporting the data to a file. To export the data, you can use Logstash with the opensearch input plugin and the file output plugin
