22.5.10.32 The ndbinfo restart_info Table
The restart_info
table contains information
about node restart operations. Each entry in the table
corresponds to a node restart status report in real time from a
data node with the given node ID. Only the most recent report
for any given node is shown.
The following table provides information about the columns in
the restart_info
table. For each column, the
table shows the name, data type, and a brief description.
Additional information can be found in the notes following the
table.

Initial state |
Status numbers 0 through 12 apply on master nodes only; the remainder of those shown in the table apply to all restarting data nodes. Status numbers 13 and 14 define node failure states; 20 and 21 occur when no information about the restart of a given node is available.
