The value is one of int, uint (unsigned integer), double, decimal, datetime, or string (includes character and binary strings). The column_statistics data dictionary table stores histogram statistics about column values, for use by the optimizer in ...
https://dev.mysql.com/doc/refman/8.0/en/partitioning-key.html
Unlike the case with other partitioning types, columns used for partitioning by KEY are not restricted to integer or NULL values. Partitioning by key is similar to partitioning by hash, except that where hash partitioning employs a user-defined ...
https://dev.mysql.com/doc/refman/8.0/en/partitioning-limitations-functions.html
Each of these functions returns an integer only if it is passed an argument of an exact numeric type, such as one of the INT types or DECIMAL. This section discusses limitations in MySQL Partitioning relating specifically to functions used in ...
https://dev.mysql.com/doc/refman/8.0/en/partitioning-pruning.html
When a table is partitioned by HASH or [LINEAR] KEY, pruning can be used only on integer columns. The optimization known as partition pruning is based on a relatively simple concept which can be described as “Do not scan partitions where there ...

The Performance Schema tables provide a container to store progress data, but make no assumptions about the semantics of the metric itself: A “work unit” is an integer metric that increases over time during execution, such as the number of ...
https://dev.mysql.com/doc/refman/8.0/en/performance-schema-timing.html
Therefore, the time unit is an integer multiple of the highest possible TIMER_FREQUENCY value, using a multiplier large enough to ensure that there is no major precision loss. Events are collected by means of instrumentation added to the server ...
