Physical tables

The Physical tables view allows you to browse details of the physical tables in the 1010data database.

The Physical tables view is available from the main PPA window and from the Finished queries and MDB state cache views. It offers a concise overview of performance-related information about physical tables, including segby, sortseg, ts breaks, indexed columns, prelinks, and distribution of data over segments, subprocesses, and machines as actually seen by the current session.
