Managing a distributed MPP database requires quick visibility into running queries, disk usage, and data distribution across nodes. GBase 8a, the China-domestically developed MPP cluster database from GBASE, provides a set of system tables that can be queried directly—but wrapping those queries into reusable stored procedures makes daily operations far more efficient.
