fix: dedupe map sub-key entries in filter sidebar (HDX-4340) (#2332)
## Summary

The filter sidebar rendered two separate accordion items for the same map sub-field (e.g. two `time (1)` rows under `LogAttributes`, both showing the same value) whenever a Lucene URL round-trip put a map filter back into `filterState`. Root cause: `filterState` stores map sub-keys in dot notation (`LogAttributes.time`) after `setFilterValue`'s `parseKeyPath().join('.')` normalization, while the facet query returns the same logical key in bracket notation (`LogAttributes['time']`); the merge in `shownFacets` treated them as distinct.

`groupFacetsByBaseName` now collapses children by `(baseName, propertyPath)` and keeps the bracket form so `child.key` stays valid for "Load more" SQL. A new `getFilterStateEntry` helper tolerates either form when reading `filterState`, so the user's selection still resolves on the merged child. Writes are unchanged.

### Screenshots or video

| Before | After |
| :----- | :---- |
| Two `time` rows under `LogAttributes`, only the first checked. | Single `time` row with the selection preserved. |

### How to test on Vercel preview

**Preview routes:** /search

**Steps:**

1. Open the Search page on a source whose `LogAttributes` (or any Map column) has at least one observed key — `service.name` is a good candidate on the demo data.
2. Append `&where=LogAttributes.service.name%3A%22api%22` (substitute any real attribute key/value) to the URL and reload.
3. Expand `LogAttributes` in the filter sidebar.
4. Verify only one row appears for the filtered key (no duplicate accordion item), the checkbox shows the selection, and clicking "Load more" surfaces additional values.

Search logs and traces all in one place

Spinning Up HyperDX

HyperDX can be deployed as part of ClickStack, which includes ClickHouse, HyperDX, OpenTelemetry Collector and MongoDB.

docker run -p 8080:8080 -p 4317:4317 -p 4318:4318 docker.hyperdx.io/hyperdx/hyperdx-all-in-one

Afterwards, you can visit http://localhost:8080 to access the HyperDX UI.

If you already have an existing ClickHouse instance, want to use a single container locally, or are looking for production deployment instructions, you can view the different deployment options in our deployment docs.

If your server is behind a firewall, you'll need to open/forward port 8080, 8000 and 4318 on your firewall for the UI, API and OTel collector respectively.

We recommend at least 4GB of RAM and 2 cores for testing.

Hosted ClickHouse Cloud

You can also deploy HyperDX with ClickHouse Cloud, you can sign up for free and get started in just minutes.

Instrumenting Your App

To get logs, metrics, traces, session replay, etc into HyperDX, you'll need to instrument your app to collect and send telemetry data over to your HyperDX instance.

We provide a set of SDKs and integration options to make it easier to get started with HyperDX, such as Browser, Node.js, and Python

You can find the full list in our docs.

OpenTelemetry

Additionally, HyperDX is compatible with OpenTelemetry, a vendor-neutral standard for instrumenting your application backed by CNCF. Supported languages/platforms include:

  • Kubernetes
  • Javascript
  • Python
  • Java
  • Go
  • Ruby
  • PHP
  • .NET
  • Elixir
  • Rust

(Full list here)

Once HyperDX is running, you can point your OpenTelemetry SDK to the OpenTelemetry collector spun up at http://localhost:4318.

Contributing

We welcome all contributions! There's many ways to contribute to the project, including but not limited to:

Motivation

Our mission is to help engineers ship reliable software. To enable that, we believe every engineer needs to be able to easily leverage production telemetry to quickly solve burning production issues.

However, in our experience, the existing tools we've used tend to fall short in a few ways:

  1. They're expensive, and the pricing has failed to scale with TBs of telemetry becoming the norm, leading to teams aggressively cutting the amount of data they can collect.
  2. They're hard to use, requiring full-time SREs to set up, and domain experts to use confidently.
  3. They requiring hopping from tool to tool (logs, session replay, APM, exceptions, etc.) to stitch together the clues yourself.

We hope you give HyperDX in ClickStack a try and let us know how we're doing!

HyperDX Usage Data

HyperDX collects anonymized usage data for open source deployments. This data supports our mission for observability to be available to any team and helps support our open source product run in a variety of different environments. While we hope you will continue to support our mission in this way, you may opt out of usage data collection by setting the USAGE_STATS_ENABLED environment variable to false. Thank you for supporting the development of HyperDX!
