please dcheck on length 4k alignment

i meant bytes.length()
Didn't we discuss above what the potential benefits of 4k alignment would be if our abstractions both ways work with byte ranges? If it's always 4k bytes, then why not count pages instead 😆

…nfly ( v1.15.1 → v1.16.0 ) (#3354) This PR contains the following updates: | Package | Update | Change | |---|---|---| | [docker.dragonflydb.io/dragonflydb/dragonfly](https://github.com/dragonflydb/dragonfly) | minor | `v1.15.1` -> `v1.16.0` | --- ### Release Notes <details> <summary>dragonflydb/dragonfly (docker.dragonflydb.io/dragonflydb/dragonfly)</summary> ### [`v1.16.0`](https://github.com/dragonflydb/dragonfly/releases/tag/v1.16.0) [Compare Source](https://github.com/dragonflydb/dragonfly/compare/v1.15.1...v1.16.0) ##### Dragonfly v1.16.0 Our spring release. We are getting closer to 2.0 with some very exciting features ahead. Stay tuned! Some prominent changes include: - Improved memory accounting of client connections ([#​2710](https://github.com/dragonflydb/dragonfly/issues/2710) [#​2755](https://github.com/dragonflydb/dragonfly/issues/2755) and [#​2692](https://github.com/dragonflydb/dragonfly/issues/2692) ) - FT.AGGREGATE call ([#​2413](https://github.com/dragonflydb/dragonfly/issues/2413)) - Properly handle and replicate Memcache flags ([#​2787](https://github.com/dragonflydb/dragonfly/issues/2787) [#​2807](https://github.com/dragonflydb/dragonfly/issues/2807)) - Intoduce BF.AGGREGATE BD.(M)ADD and BF.(M)EXISTS methods ([#​2801](https://github.com/dragonflydb/dragonfly/issues/2801)). Note, that it does not work with snapshots and replication yet. - Dragonfly builds natively on MacOS. We would love some help with extending the release pipeline to create a proper macos binary. - Following the requests from the Edge developers community, we added a basic HTTP API support! Try running Dragonfly with: `--expose_http_api` flag and then call `curl -X POST -d '["ping"]' localhost:6379/api`. We will follow up with more extensive docs later this month. - Lots of stability fixes, especially around Sidekiq and BullMQ workloads. ##### What's Changed - chore: make usan asan optional and enable them on CI by [@​kostasrim](https://github.com/kostasrim) in [https://github.com/dragonflydb/dragonfly/pull/2631](https://github.com/dragonflydb/dragonfly/pull/2631) -
