enhancement(compression): zstd compression support #17371

Merged

Conversation

Add zstd compression support (#17324, possibly #2302):

  • added ZstdEncoder. Wrapped it with struct with Sync implementation. Had to add unsafe, since zstd encoder doesn't implement Sync. But it looks safe, because all writing stuff requires a unique reference and the wrapper is allowed to share internal Write, which implements Sync too.
  • refactored CompressionLevel, since the old struct was tied closely to a flate2 implementation and it's defaults don't fit well to zstd.

Yeah, I wanted to add Zstd support to this part of Vector a bit later but @akoshchiy was faster :) Glad to see that not only me is interested in Zstd expansion in Vector!

I second all of the unresolved comments Spencer has left, but otherwise this looks good, particularly the cleanup of the compression level types.

Rust is usually able to auto-derive Sync when it is safe to do so. Do you know why this manual impl is necessary?

It's required to be a Sync by DatadogMetricsRequestBuilder, which owns a Compressor instance.
zstd::Encoder is not Sync because of the internal struct ZSTD_CCtx_s , which does not implement Sync.
The details are here gyscos/zstd-rs#186.

So, I think, it's pretty safe to declare unsafe Sync here, because:

  1. we are not sharingzstd::Encoder, only internal impl Write, which should implement Sync;
  2. using the ZstdEncoder itself for compressing requires &mut self, which also means that we can't share it.

Same workaround is using by async-compression - zstd encoder is wrapped by Unshared struct, which gives only a mutable ref to encoder.

https://github.com/Nullus157/async-compression/blob/6d453d88bb2eb301cbbc9a60bb2b61d3a88be14d/src/codec/zstd/encoder.rs#LL7C17-L7C17

Works for me. If we end up having more of these, it would probably be worth bringing in the Unshared wrapper type to consolidate the logic, but otherwise this should be fine as-is.

Regression Detector Results

Run ID: d1784908-40be-43df-96b3-ccffb7784e56
Baseline: 187f142
Comparison: c33dd8e
Total vector CPUs: 7

Explanation

A regression test is an integrated performance test for vector in a repeatable rig, with varying configuration for vector. What follows is a statistical summary of a brief vector run for each configuration across SHAs given above. The goal of these tests are to determine quickly if vector performance is changed and to what degree by a pull request.

Because a target's optimization goal performance in each experiment will vary somewhat each time it is run, we can only estimate mean differences in optimization goal relative to the baseline target. We express these differences as a percentage change relative to the baseline target, denoted "Δ mean %". These estimates are made to a precision that balances accuracy and cost control. We represent this precision as a 90.00% confidence interval denoted "Δ mean % CI": there is a 90.00% chance that the true value of "Δ mean %" is in that interval.

We decide whether a change in performance is a "regression" -- a change worth investigating further -- if both of the following two criteria are true:

  1. The estimated |Δ mean %| ≥ 5.00%. This criterion intends to answer the question "Does the estimated change in mean optimization goal performance have a meaningful impact on your customers?". We assume that when |Δ mean %| < 5.00%, the impact on your customers is not meaningful. We also assume that a performance change in optimization goal is worth investigating whether it is an increase or decrease, so long as the magnitude of the change is sufficiently large.

  2. Zero is not in the 90.00% confidence interval "Δ mean % CI" about "Δ mean %". This statement is equivalent to saying that there is at least a 90.00% chance that the mean difference in optimization goal is not zero. This criterion intends to answer the question, "Is there a statistically significant difference in mean optimization goal performance?". It also means there is no more than a 10.00% chance this criterion reports a statistically significant difference when the true difference in mean optimization goal is zero -- a "false positive". We assume you are willing to accept a 10.00% chance of inaccurately detecting a change in performance when no true difference exists.

The table below, if present, lists those experiments that have experienced a statistically significant change in mean optimization goal performance between baseline and comparison SHAs with 90.00% confidence OR have been detected as newly erratic. Negative values of "Δ mean %" mean that baseline is faster, whereas positive values of "Δ mean %" mean that comparison is faster. Results that do not exhibit more than a ±5.00% change in their mean optimization goal are discarded. An experiment is erratic if its coefficient of variation is greater than 0.1. The abbreviated table will be omitted if no interesting change is observed.

No interesting changes in experiment optimization goals with confidence ≥ 90.00% and |Δ mean %| ≥ 5.00%.

Thanks for extending the unit tests!

Looks like you need to run make generate-component-docs to re generate the docs from your changes.

So, I see a lot of failures in CI, but I'm not sure that they are caused by the PR changes, e.g. datadog integration failed with TEST_DATADOG_API_KEY required. Is it known issue?

Yeah, I was just talking to @neuronull about this - those jobs have GH secrets that aren't available to external contributors, hopefully we'll make some updates to have those ignored unless a maintainer opened the PR. I'll merge this manually 👍
