You want to start monitoring statistics on the distribution of storage engines that are being used and the average sizes of tables in the various databases.
Some details are as follows:
-The Mysql instance has 400 databases.
-Each database on an average consists of 25-50 tables.
You use the query:
SELECT TABLE_SCHEMA,
'ENGINE',
COUNT (*),
SUM (data_length) total_size
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
GROUP BY TABLE_SCHEMA, 'ENGINE'
;
Why is this query slow to execute?
