latest_file_io and x$latest_file_io Sys Schema Views
MariaDB starting with 10.6
These Sys Schema views were introduced in MariaDB 10.6.
Description
The latest_file_io and x$latest_file_io views summarize file I/O activity, grouped by file and thread. Rows are sorted by most recent I/O by default.
The latest_file_io view is intended to be easier for human reading, while the x$latest_file_io view provides the data in raw form, intended for tools that process the data.
They contain the following columns:
| Column | Description |
|---|---|
| thread | Account associated with the thread for foreground threads (port number for TCP/IP connections), or thread name and thread ID for background threads. |
| total | Total number of occurrences of the I/O event. |
| file | File path name. |
| latency | Wait time of the file I/O event. |
| operation | Type of operation |
| requested | Number of bytes requested for the file I/O event. |
