Impact of Querying Table Information From information_schema

Percona

MARCH 27, 2023

A lot of useful information can be retrieved from this schema, for example, table metadata and foreign key relations, but trying to query I_S can induce performance degradation if your server is under heavy load, as shown in the following example test. The same tests have been executed in Percona Server for MySQL 5.7

AB Testing?—?So The first thing I found was that every user visible change we made went through an A/B test. An oft-quoted study by Microsoft Bing found that of the changes they test, one-third prove effective, one-third have neutral results, and one-third have negative results.

How Many Warehouses for the HammerDB TPC-C Test?

HammerDB

OCTOBER 17, 2018

The official TPC-C test has a fixed number of users per warehouse and uses keying and thinking time so that the workload generated by each user is not intensive. With HammerDB this home warehouse is chosen at random at the start of the test and remains fixed. Additionally it is important to understand the workload.
