Create a CLI for uploading and downloading blocks by kushalShukla-web · Pull Request #760 · prometheus/test-infra

kushalShukla-web · 2024-09-24T14:58:47Z

This PR introduces a CLI tool for seamless block uploading and downloading. The initial implementation leverages an object storage as the storage backend, with the potential for other storage backends in the future.

Added a dedicated upload function for uploading data to the object store, with error handling and status logs using log/slog.
A separate download function was created to fetch data from the object store.
Structured logging is a key feature of this PR, made possible by the utilization of the log/slog package. This enables easier traceability and debugging during storage operations.
Insured clear separation of concerns by modularizing upload and download logic into distinct functions.
Integrated the Thanos object storage package to facilitate efficient data storage and retrieval handling.

Test plan

Manual testing locally against a Minio service.

I see 'upload'; will you be downloading data at some point?

I see 'upload'; will you be downloading data at some point?

yes @bboreham I have to implement both upload and download functionality.

@kushalShukla-web Also, we should work on the PR title and the description.

Please also sign your commits https://github.com/prometheus/test-infra/pull/760/checks?check_run_id=30633470860

It's going in a good direction. Thanks a lot. I have commented. We need to clean up the architecture.

We should also work on the naming and documentation. We miss the README as well.

This function returns an error. Why do we panic? Let's just return the error.

Suggested change

bucket, err := client.NewBucket(log.NewNopLogger(), configBytes, "example")

bucket, err := client.NewBucket(log.NewNopLogger(), configBytes, "block-sync")

We could use a proper component name.

example is wrong here, no? This should be a parent directory we get as a command line argument.

I think if we move this to line 34, it will not be able to recognize the download and upload functions because these lines are declared below.

We've discussed this PR on video-call and on Slack; I'm repeating a couple of points here:

Make this PR just the CLI program; pull out the yamls and scripting to another PR.
Get the images updated in one PR, then change the yamls that use them. We can't merge a change to use your privately-built image.

+    type: S3


This is going to be configured differently for each installation - s3 is good for local installs using Minio, but when run at Google Cloud it needs to say gcs.
I suggest you take this Secret out of the PR and instead put instructions in the docs, e.g. here, for the person who installs Prombench to set it up.

+kind: Secret
+metadata:
+  name: s3-secret
+  namespace: prombench-{{ .PR_NUMBER }}  # Replace with your actual namespace


I see you put the Secret in the namespace for the PR, but I see the same bucket being used across many runs.

Key changes 1. removed multiline command and put it in script on prometheus-builder image. 2. configure this in prometheus deployment. 3. added download.sh script which will download the data if key present , else skip the downloading process and move to next container.

bboreham · 2024-11-07T15:29:38Z

One thing that could be added (not vital right now) is to be able to upload several blocks.

Example:

# du -h
4.6G    ./01JC3JCA8Y39ZV72Y0F0FEEQND/chunks
5.8G    ./01JC3JCA8Y39ZV72Y0F0FEEQND
1.5G    ./01JC3J7CCY83F1EZGCBMEPG2RY/chunks
1.9G    ./01JC3J7CCY83F1EZGCBMEPG2RY
4.6G    ./01JC2XS9SGSE6YTKJZSAJP3YR8/chunks
5.8G    ./01JC2XS9SGSE6YTKJZSAJP3YR8
[...]
958.2M  ./chunks_head
85.4M   ./wal/checkpoint.00002015
4.2G    ./wal

I can specify one block, e.g. 01JC3J7CCY83F1EZGCBMEPG2RY, but I can't specify two.
If I upload the entire Prometheus data direectory I will get wal and chunks_head, which we don't want to download for a subsequent Prombench run.
