Append new columns. Reshape data.

[juanpide]

How can I append new columns to a TileDB table? How can I reshape a table (larger than memory) from wide to long formats or viceversa? Is there any example on how to do it?

TileDB does not currently support any kind of array schema alteration. This is in our roadmap, being tracked here: https://feedback.tiledb.com/tiledb-core/p/schema-evolution

We will try to add this feature very soon.
