Jonathan Eagles commented on YARN-3437:

Now that I have dug into timeline server performance (YARN-3448). I have a 
better understanding of what type of writes are costly. For example, a single 
entity will generate dozens or writes to the database. The number of primary 
keys, the number of related entities, and the write batch size (entities per 
put) greatly affect the time an entity put takes. While this is a good start, I 
think there should at least be a follow up that addresses these issues to 
better measure the write performance.
