tiledb_query_get_est_result_size_var.Rd
When reading variable-length attributes from either dense or sparse arrays, one cannot know beforehand how big the result will be (unless one actually executes the query). This function offers a way to get the estimated result size for the given attribute. As TileDB does not actually execute the query, getting the estimated result is very fast.
