tiledb_array_apply_aggregate

Run an aggregate query on the given array and attribute

The modern database 'TileDB' introduces a powerful on-disk
format for multi-modal data based on dimensional arrays. It supports
dense and sparse arrays, dataframes and key-values stores, cloud
storage ('S3', 'GCS', 'Azure'), chunked arrays, multiple compression,
encryption and checksum filters, uses a fully multi-threaded
implementation, supports parallel I/O, data versioning ('time
travel'), metadata and groups. It is implemented as an embeddable
cross-platform C++ library with APIs from several languages, and
integrations.
