MySQL 8.3 Release Notes
The blocks table is a static table which
simply contains the names and internal IDs of all NDB kernel
blocks (see NDB Kernel Blocks). It
is for use by the other
ndbinfo tables (most of which
are actually views) in mapping block numbers to block names for
producing human-readable output.
The blocks table contains the following
columns:
block_numberBlock number
block_nameBlock name
Notes
To obtain a list of all block names, simply execute
SELECT block_name FROM ndbinfo.blocks.
Although this is a static table, its content can vary between
different NDB Cluster releases.
