If we start supporting external catalogs then "drop database" may be
misleading (and not possible). We should be more clear that this is a
utility method to drop all tables. This is also a nice chance for some
consistency cleanup as it was `drop_db` in rust, `drop_database` in
python, and non-existent in typescript.
This PR also adds a public accessor to get the database trait from a
connection.
BREAKING CHANGE: the `drop_database` / `drop_db` methods are now
deprecated.
Similar to
c269524b2f
this PR reworks and exposes an internal trait (this time
`TableInternal`) to be a public trait. These two PRs together should
make it possible for others to integrate LanceDB on top of other
catalogs.
This PR also adds a basic `TableProvider` implementation for tables,
although some work still needs to be done here (pushdown not yet
enabled).
Closes#1106
Unfortunately, these need to be set at the connection level. I
investigated whether if we let users provide a callback they could use
`AsyncLocalStorage` to access their context. However, it doesn't seem
like NAPI supports this right now. I filed an issue:
https://github.com/napi-rs/napi-rs/issues/2456
This opens up the door for more custom database implementations than the
two we have today. The biggest change should be inivisble:
`ConnectionInternal` has been renamed to `Database`, made public, and
refactored
However, there are a few breaking changes. `data_storage_version` and
`enable_v2_manifest_paths` have been moved from options on
`create_table` to options for the database which are now set via
`storage_options`.
Before:
```
db = connect(uri)
tbl = db.create_table("my_table", data, data_storage_version="legacy", enable_v2_manifest_paths=True)
```
After:
```
db = connect(uri, storage_options={
"new_table_enable_v2_manifest_paths": "true",
"new_table_data_storage_version": "legacy"
})
tbl = db.create_table("my_table", data)
```
BREAKING CHANGE: the data_storage_version, enable_v2_manifest_paths
options have moved from options to create_table to storage_options.
BREAKING CHANGE: the use_legacy_format option has been removed,
data_storage_version has replaced it for some time now
* Make `npm run docs` fail if there are any warnings. This will catch
items missing from the API reference.
* Add a check in our CI to make sure `npm run dos` runs without warnings
and doesn't generate any new files (indicating it might be out-of-date.
* Hide constructors that aren't user facing.
* Remove unused enum `WriteMode`.
Closes#2068
Some Rust jobs (such as
[Rust/linux](https://github.com/lancedb/lancedb/actions/runs/13019232960/job/36315830779))
take almost minutes. This can be a bit of a bottleneck.
* Two fixes to make caches more effective
* Check in `Cargo.lock` so that dependencies don't change much between
runs
* Added a new CI job to validate we can build without a lockfile
* Altered build commands so they don't have contradictory features and
therefore don't trigger multiple builds
Sadly, I don't think there's much to be done for windows-arm64, as much
of the compile time is because the base image is so bare we need to
install the build tools ourselves.
This PR aims to fix#2047 by doing the following things:
- Add a distance_type parameter to the sync query builders of Python
SDK.
- Make metric an alias to distance_type.
* `createTable()` now saves embeddings in the schema metadata.
Previously, it would drop them. (`createEmptyTable()` was already tested
and worked.)
* `mergeInsert()` now uses embeddings.
Fixes#2066
Fixes#2031
When we do hybrid search, we normalize the scores. We do this
calculation in-place, because the Rerankers expect the `_distance` and
`_score` columns to be the normalized ones. So I've changed the logic so
that we restore the original distance and scores by matching on row ids.
When calling `replace_field_metadata` we pass in an iter of tuples
`(u32, HashMap<String, String>)`.
That `u32` needs to be the field id from the lance schema
7f60aa0a87/rust/lance-core/src/datatypes/field.rs (L123)
This can sometimes be different than the index of the field in the arrow
schema (e.g. if fields have been dropped).
This PR adds docs that try to clarify what that argument should be, as
well as corrects the usage in the test (which was improperly passing the
index of the arrow schema).
This includes several improvements and fixes to the Python Async query
builders:
1. The API reference docs show all the methods for each builder
2. The hybrid query builder now has all the same setter methods as the
vector search one, so you can now set things like `.distance_type()` on
a hybrid query.
3. Re-rankers are now properly hooked up and tested for FTS and vector
search. Previously the re-rankers were accidentally bypassed in unit
tests, because the builders overrode `.to_arrow()`, but the unit test
called `.to_batches()` which was only defined in the base class. Now all
builders implement `.to_batches()` and leave `.to_arrow()` to the base
class.
4. The `AsyncQueryBase` and `AsyncVectoryQueryBase` setter methods now
return `Self`, which provides the appropriate subclass as the type hint
return value. Previously, `AsyncQueryBase` had them all hard-coded to
`AsyncQuery`, which was unfortunate. (This required bringing in
`typing-extensions` for older Python version, but I think it's worth
it.)
