@xdk-amz You write 'All the language bindings should be implemented and the example files should be linked in the blog before publishing.' That's a publishing dependency. Can you please explain more so we can plan this one out? |
|
@stockholmux valkey-io/valkey-glide#5299 here is the epic tracking that work |
|
bump @stockholmux the feature is preparing for a release in 2.4 We would like to pair the feature release with the blog, so feedback would be appreciated |
|
@xdk-amz We're currently in a cadence with the the release of Valkey 9.1 so publishing capacity is very tight. Let me see what I can do. |
|
@valkey-io/technical-blog-reviewers may we please get review on this blog? |

I like the blog post.
Needs some updating and there are some language issues that need to be tightened up.
It's a little long and feels repetitious - can you keep the technical level but condense it?

@xdk-amz Please see the technical reviewers comments on this PR. If you have any questions, please do let us know. |

- Line 16: Update the LZ4 summaries at
content/blog/2026-03-16-transparent-compression/index.md:16-16 and :173-173 to
use qualified wording such as “low overhead in this benchmark” instead of
claiming effectively zero impact or being effectively free; at :173-173, also
cite the measured 0.87x–1.07x SET throughput range.
- Line 4: Align the post’s front-matter date with the publication path
`2026-03-16`: update the `date` value to the intended March 16, 2026 publication
date, or rename the directory if July 1, 2025 is canonical. Ensure both
represent one consistent publication date.
- Around line 47-58: Revise the compression compatibility note and Unsupported
Commands section to describe command-specific failures: numeric operations may
error, reads and bit operations may inspect compressed bytes, and mutations may
corrupt the stored frame so it cannot be decoded. Remove the recommendation to
replicate commands client-side, and instead recommend uncompressed keys or an
explicitly concurrency-safe design.
- Line 169: The compression rollout guidance must not imply that unconfigured
clients can safely read data rewritten by compression-enabled clients. Update
the paragraph to require compression support for every reader of affected keys,
or document a versioned/dual-read-write rollout with explicit cutover steps, and
remove the unconditional “no migration scripts, no downtime” promise.
- Around line 18-30: Update the “To get started” section to link to complete
standalone and cluster GLIDE examples, or explicitly label the shown Go blocks
as partial snippets. If keeping them as runnable examples, define ctx and
userDataJSON, handle the error returned by glide.NewClient, and close the client
before completion.
- Line 43: Update the compression interoperability statement in the blog content
to remove the claim that zstd- and LZ4-configured clients can read each other’s
data. Retain the cross-language shared-header claim, and replace the backend
wording with the configuration terminology used in the compression
documentation.

- Line 18: Revise the LZ4 performance description in the blog text to avoid
claiming effectively zero or invisible impact. Qualify it with the benchmarked
throughput range and the small batch-10 p50 latency increase, or limit the claim
explicitly to typical configurations while preserving the reported 2KB JSON
workload context.
- Line 105: Regenerate the compression benchmarks using Valkey 9, then replace
all affected tables, charts, and derived claims with results from that run;
update the methodology around the benchmark description to accurately identify
the Valkey 9 server. Do not merely change the existing version text without
refreshing the underlying data and conclusions.
- Line 3: Update the compression savings claim in the post description and
introduction to match the benchmark’s 49.7% result, using 49.7% consistently
throughout the article.
- Line 48: Update the compression behavior description to avoid claiming GLIDE
frames are never double-compressed: qualify the guarantee to frames produced by
the same backend, or update the implementation to detect the generic GLIDE
header before compressing.

| If you're caching JSON API responses, storing user sessions, or buffering HTML fragments in Valkey, there's a good chance your data is highly compressible while you're still paying full price to store every byte. Even if your overall cache footprint is small, networking fees can still drive up your costs. Many of these cached values contain redundant data that compression can reduce by up to 49%, directly reducing costs by a similar factor. Implementing compression within your application means pulling in new dependencies and modifying application logic. What if your Valkey client could just do it for you? |

| A few safety-by-default choices keep compression from ever getting in the way: if compression fails for any reason, GLIDE silently falls back to uncompressed data. Data that already carries the GLIDE header won't be double-compressed. And after compressing, GLIDE compares sizes: if compression didn't help, the original goes through unchanged. | ||

| ## The Core Tradeoff: Memory vs Throughput | ||
| ### Methodology | ||
|
|
||
| Benchmarks were generated using the Go GLIDE client on Amazon EC2 r7g.2xlarge instances (8 ARM vCPUs, 64 GB RAM, AWS Graviton3) with the client and Valkey 9.0.3 server running on separate hosts in the same AWS VPC. The test corpus was JSON strings averaging ~1,884 bytes per value. This value size was chosen to drive compression to its limits by giving the compression algorithms enough data to work with while still being sensibly-sized. A benchmark script swept a matrix of 80 configurations across goroutine counts (1, 2, 4, 8, 10, 25, 100, 1000) and pipeline batch sizes (1, 5, 10, 20, 50). |

Description
Adds a blog that walks through the new Transparent Compression feature from the perspective of a Go client user. The blog contains examples and benchmark data for different client configurations to help inform potential users of the benefits based on their workload.
There is still some TODO work on the blog but I want to get early feedback so I can iterate on the structure and content. I think I have way too many graphs and can probably cut down on some but I love graphs so I have left them in and will pare down from here if requested.
