Question

How can I determine the bytes per row and/or column for a specific schema.table in Vertica?

Was it helpful?

Solution

You want to use the following system table: column_storage

It has all the information you need. Row count and bytes per projection per node. You can always query it using SUM() to get the cut you want.
