The current treatment of JSON paths is a bit messy in our code. Our JSON manipulation functions parse these paths in an ad-hoc way. This is error-prone, and is not...

Don't rebuild HNSW when updating non-indexed fields

Closes #2705. This PR lets the caller of `SegmentHolder::apply_points_to_appendable()` (renamed to `apply_points_and_reindex`) to specify whether it is OK to update non-appendable segments. It is safe when a non-indexed field is...

Replace raw `usize` with an enum for telemetry details level. So now we can use "find references" feature of IDEs to find all the places where details level is significant....

Closes #3433. The shard progress state is tracked locally inside `TransferTasksPool` (aka `Collection::transfer_tasks`). Since it's local, only the sender node shows the progress in the result of `GET collections/{name}/cluster`. Output...

Unify end-to-end tests

**Is your feature request related to a problem? Please describe.** As a new contributor, I find the process of running all of the end-to-end tests to be complicated. There are...

Issue #3333. This PR adds the feature `use_f32` to crate `segment`, enabled by default. If disabled, `half::f16` is used instead of `f32`. It seems, that just changing the type alias...
