#### 23.6.14.61 The ndbinfo threadblocks Table

[]()

 The `threadblocks` table associates data nodes, threads, and instances of `NDB` kernel blocks.

 The `threadblocks` table contains the following columns:

* `node_id`

   Node ID

* `thr_no`

   Thread ID

* `block_name`

   Block name

* `block_instance`

   Block instance number

##### Notes

 The value of the `block_name` in this table is one of the values found in the `block_name` column when selecting from the [`ndbinfo.blocks`](mysql-cluster-ndbinfo-blocks.html) table. Although the list of possible values is static for a given NDB Cluster release, the list may vary between releases.

 The `block_instance` column provides the kernel block instance number.
