Some processing on arrays (e.g., convolution) requires "tile overlaps". In other words, it is sometimes necessary to declare an array that consists of tiles which overlap certain amounts with one another. I think that TileDB would be better if the feature is supported.

Feature request in support of multi-array groups/collections: support the storage of metadata, a la Array.meta, on a group.

Enable use of TileDB from Julia (www.julialang.org).

TileDB does not allow arrays to change size. Appending new data and removing old data along a specific dimension (ex. time) is useful for realtime applications.

Currently, all array dimensions must be of the same type. TileDB should support dimensions of different types as well.

TileDB should support attaching axes labels (dataframes in their full generality), so that the user can slice the array based on arbitrary axes label predicates.

TileDB currently performs only slicing. It should allow other computations, such as filters, group-by queries and joins. This will help high-level application push compute closer to storage.

This will enable TileDB to support fast out-of-core key-value queries. In addition, it will be able support ND and prefix string queries.

TileDB should support slicing with strides, which is quite common in numpy and similar tools.
