The tool reports that there are no NDB  BLOB column parts associated with column c1 , even though c1 is a TEXT  column. This is due to the fact that, in an NDB  table, only the first 256 bytes of a BLOB  or TEXT column value are stored inline, and only the excess, if any, is stored separately; thus, if there are no values using more than 256 bytes in a given column of one of these types, no BLOB  column parts are created by NDB  for this column. See Section 11.7, “Data Type Storage Requirements” , for more information. 

## 23.4.7 ndb_config — Extract NDB Cluster Configuration Information 

This tool extracts current configuration information for data nodes, SQL nodes, and API nodes from one of a number of sources: an NDB Cluster management node, or its config.ini  or my.cnf  file. By default, the management node is the source for the configuration data; to override the default, execute ndb_config with the --config-file  or --mycnf  option. It is also possible to use a data node as the source by specifying its node ID with --config_from_node= node_id . 

ndb_config  can also provide an offline dump of all configuration parameters which can be used, along with their default, maximum, and minimum values and other information. The dump can be produced in either text or XML format; for more information, see the discussion of the --configinfo  and --xml options later in this section). 

You can filter the results by section ( DB , SYSTEM , or CONNECTIONS ) using one of the options --nodes , -- system , or --connections . 

All options that can be used with ndb_config  are shown in the following table. Additional descriptions follow the table.
