Zhaocun Sun ec82e36317 docs(python): document in-memory connections (#3434)
## Problem

Issue #2247 notes that the Python docs do not show how to use LanceDB's
in-memory backend via `connect("memory://")`.

## Solution

Add `memory://` examples to the sync and async `connect` docstrings, and
call out that in-memory databases are intended for tests/temporary data
and are not persisted.

## Validation

- `python3 -m py_compile python/python/lancedb/__init__.py`
- `git diff --check`

## Confidence

82/100 — docs-only update, directly tied to the documented missing
`memory://` usage. It changes API documentation only and was syntax/diff
validated.

Closes #2247.

LanceDB Python SDK

A Python library for LanceDB.

Installation

pip install lancedb

Preview Releases

Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.

pip install --pre --extra-index-url https://pypi.fury.io/lancedb/ lancedb

Usage

Basic Example

import lancedb
db = lancedb.connect('<PATH_TO_LANCEDB_DATASET>')
table = db.open_table('my_table')
results = table.search([0.1, 0.3]).limit(20).to_list()
print(results)
