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_number- Block number 
- block_name- Block 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.
