These operations have existed in lance for a long while and many users need to drop down to lance for this capability. This PR adds the API and implements it using filters (e.g. `_rowid IN (...)`) so that in doesn't currently add any load to `BaseTable`. I'm not sure that is sustainable as base table implementations may want to specialize how they handle this method. However, I figure it is a good starting point. In addition, unlike Lance, this API does not currently guarantee anything about the order of the take results. This is necessary for the fallback filter approach to work (SQL filters cannot guarantee result order)
LanceDB
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
