Description:
More insight into NDB scheduler operation is needed

How to repeat:
Feature request

Suggested fix:
Add a new ndbinfo table schedstat that reports various counters and histograms of NDB scheduler operations.
[11 Jan 2016 12:30] Jon Stephens 
Documented the feature addition in the NDB 4.7.9 changelog as follows:

    Added the tc_time_track_stats table to the ndbinfo information 
    database. This table provides time-tracking information relating to
    transactions, key operations, and scan operations performed by NDB.

Also documented the table and its columns in the NDB 7.4+ documentation using the column descriptions from src/kernel/vm/Ndbinfo.hpp.

Closed.
