In tiledb: Universal Storage Engine for Sparse and Dense Multidimensional Arrays

Retrieve the estimated result size for a query and variable-sized attribute

Description

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.

Usage

tiledb_query_get_est_result_size_var(query, name)

Arguments

query	A TileDB Query object
name	A variable with an attribute name

Value

An estimate of the query result size
