What performs a key distribution analysis and stores the distribution for the named table or tables?

Solution (By Examveda Team)

This question is asking about a MySQL command that helps analyze and store the distribution of data within a table.
Let's break down the options:
Option A: ANALYZE TABLE
This is the correct answer! The ANALYZE TABLE command does exactly what the question describes. It performs a key distribution analysis (finding out how data is spread across different keys) and saves this information for the specified table(s). This information can then be used by MySQL to optimize queries and make them run faster.
Option B: CHECK TABLE
CHECK TABLE is used to check the integrity of a table. It makes sure that all the data is consistent and that there are no errors in the table structure. It doesn't analyze key distribution.
Option C: CHECKSUM TABLE
CHECKSUM TABLE calculates a checksum for a table. This is a way to verify the integrity of the data, but it doesn't analyze the distribution of keys.
Option D: OPTIMIZE TABLE
OPTIMIZE TABLE is used to optimize a table by reorganizing its data on disk. This can improve query performance, but it doesn't directly perform key distribution analysis.
In Summary:
The command that performs a key distribution analysis and stores the distribution is ANALYZE TABLE.
It's like taking a snapshot of how data is spread across the different keys within your table. This information helps MySQL make smarter decisions when executing queries.
