This happens because openai API errors out with None values. The current
log level didn't really print out the msg on screen. Changed the log
level to warning, which better suits this case.
Also, retry loop can be disabled by setting `max_retries=0` (I'm not
sure if we should also set this as the default behaviour as hitting api
rate is quite common when ingesting large corpus)
```
func = get_registry().get("openai").create(max_retries=0)

It's confusing to users that keyword arguments from the async API like
`storage_options` are accepted by `connect()`, but don't do anything. We
should error if unknown arguments are passed instead.
This was already configurable in the rust API but it wasn't actually
being passed down to the underlying dataset. I added this option to both
the async python API and the new nodejs API.
I also added this option to the synchronous python API.
I did not add the option to vectordb.
1. added rename_table fn to enable dashboard to rename a table
2. added index_type and distance_type (for vector index) to index_stats
so that more detailed data can be shown on the table page.
closes#1194#1172#1124#1208
@wjones127 : `if query_type != "fts":` is needed because both fts and
vector search create `LanceQueryBuilder` which has `vector_column_name`
as a required attribute.
Exposes `storage_options` in LanceDB. This is provided for Python async,
Node `lancedb`, and Node `vectordb` (and Rust of course). Python
synchronous is omitted because it's not compatible with the PyArrow
filesystems we use there currently. In the future, we will move the sync
API to wrap the async one, and then it will get support for
`storage_options`.
1. Fixes#1168
2. Closes#1165
3. Closes#1082
4. Closes#439
5. Closes#897
6. Closes#642
7. Closes#281
8. Closes#114
9. Closes#990
10. Deprecating `awsCredentials` and `awsRegion`. Users are encouraged
to use `storageOptions` instead.
- make open table behaviour consistent:
- remote tables will check if the table exists by calling /describe and
throwing an error if the call doesn't succeed
- this is similar to the behaviour for local tables where we will raise
an exception when opening the table if the local dataset doesn't exist
- The table names are cached in the client with a TTL
- Also fixes a small bug where if the remote error response was
deserialized from JSON as an object, we'd print it resulting in the
unhelpful error message: `Error: Server Error, status: 404, message: Not
Found: [object Object]`

Description
Exposes pyarrow batch api during query execution - relevant when there
is no vector search query, dataset is large and the filtered result is
larger than memory.

In
2de226220b
I added a new `IntoArrow` trait for adding data into a table.
Unfortunately, it seems my approach for implementing the trait for
"things that are already record batch readers" was flawed. This PR
corrects that flaw and, conveniently, removes the need to box readers at
all (though it is ok if you do).
This PR adds support for passing through a set of ordering fields at
index time (unsigned ints that tantivity can use as fast_fields) that at
query time you can sort your results on. This is useful for cases where
you want to get related hits, i.e by keyword, but order those hits by
some other score, such as popularity.
I.e search for songs descriptions that match on "sad AND jazz AND 1920"
and then order those by number of times played. Example usage can be
seen in the fts tests.

HuggingFace Dataset is written as arrow batches.
For DatasetDict, all splits are written with a "split" column appended.

Usage Reranking with FTS:

{"text": "Capital punishment (the death penalty) has existed in the United States since before the United States was a country. As of 2017, capital punishment is legal in 30 of the 50 states."},
{"text": "North Dakota is a state in the United States. 672,591 people lived in North Dakota in the year 2010. The capital and seat of government is Bismarck."},

I know there's a larger effort to have the python client based on the
core rust implementation, but in the meantime there have been several
issues (#1072 and #485) with some of the azure blob storage calls due to
pyarrow not natively supporting an azure backend. To this end, I've
added an optional import of the fsspec implementation of azure blob
storage [`adlfs`](https://pypi.org/project/adlfs/) and passed it to
`pyarrow.fs`. I've modified the existing test and manually verified it
with some real credentials to make sure it behaves as expected.
It should be now as simple as:
```python
import lancedb
db = lancedb.connect("az://blob_name/path")
table = db.open_table("test")
table.search(...)
```
Thank you for this cool project and we're excited to start using this
for real shortly! 🎉 And thanks to @dwhitena for bringing it to my
attention with his prediction guard posts.
