Hi all!
I'm wondering what people think of a possibility to extend DataFusion so as
to accommodate time-travel querying? This would work well with the new
table formats, particularly Iceberg and Delta Lake, where table versioning
is at the core of the protocol.
You can see some details in the
Aha thanks both! I ended up using the Acero example to do it.

Li,
Here's a standalone C++ example that constructs a Table and executes
an Acero ExecPlan to sort it:

Hi,
I am writing some C++ test and found myself in need for an c++ function to
sort an arrow Table. Before I go around implementing one myself, I wonder
if there is already a function that does that? (I searched the doc but
didn’t find one).
There is function in Acero can do it but I didn’t find
Hi all,
Getting back to this thread as I realize there were a few unanswered questions.
Adding a bit more context on the rationale and usage of ArrayViews in Velox,
and the importance to standardize it:
re: Why do we need it?
We use ArrayViews for two main reasons. First, for efficient
Hey all!
Besides the recently added FixedShapeTensor [1] canonical extension type
there appears to be a need for an already proposed VariableShapeTensor
[2]. VariableShapeTensor
would store tensors of variable shapes but uniform number of
dimensions, dimension names and dimension permutations.
