| ### Version 8.19+ and 9.1+ [ec_version_8_19_and_9_1] | ||

| `apm-server.sampling.tail.ttl` | ||
| : Time-to-live (TTL) for trace events stored in the local storage of the APM Server during tail-based sampling. This TTL determines how long trace events are retained in the local storage while waiting for a sampling decision to be made. A greater TTL value increases storage space requirements. | ||

| ### Version 8.0+ [ec_version_8_0_3] |
There was a problem hiding this comment.
[to reviewer] I'm starting to think we should remove all 7.x and 8.x sections, as this is 9.0 docs. It still makes sense to document 9.0 vs 9.1+ though.

This looks good to me, but if you don't want this to be published until 9.1 you should hold off on merging as you mentioned.
(Spoiler: We're working on some changes to how to handle PRs like this that contain content for future versions and how to annotate version applicability of individual settings. If these features are available in docs-builder before the 9.1 release, I'll make updates here.)
