tiledb_query_get_est_result_size {tiledb}

Retrieve the estimated result size for a query and attribute

Description

When reading from 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(query, name)

Arguments

query

A TileDB Query object

name

A variable with an attribute name

Value

An estimate of the query result size
