Can't open a delta-table: Unsupported reader features required: DeletionVectors

[gz]

I'm using this crate to open a table in the delta lake format but it fails with: Transaction failed: Unsupported reader features required: [DeletionVectors] (root cause: Unsupported reader features required: [DeletionVectors])'.

I was expecting to be able to read the table

Environment

Delta-rs version: 0.26.2

Binding:

Environment: local

• OS: linux

The feature is not implemented, see #1094

Correct, this is not supported yet, you should defer to other implementations such as delta-spark if you want deletion vectors right now

[rohanjain101]

@ion-elgreco in older versions of deltalake python library, atleast table metadata of DeltaTable with deletion vectors could be read, only actual data (to_pyarrow_table()) would fail, now just reading the table metadata fails.

[mdrakiburrahman]

Using deltalake==0.25.5 worked with a table that contains deletion vectors.
deltalake==1.1.4 does not work.

IMO breaking clients is a regression in either deltalake PyPi, or delta-rs (whoever regressed).
