Hi All,
My app uses JDO with the DataStore. When writing an Entity with ~100
children a request could take somewhere between 3-10 seconds realtime and
~80331cpu_ms
~78231api_cpu_ms.
Can these numbers be improved for writes of this size? Is there a good
chance my requests will deadline?
After reading the docs and watching the IO sessions, I got the following
ideas for improving performance:
* Using the low level api with setMulti() should clump all the writes into a
single RPC. I'm guessing PersistenceManager isn't doing that for us with
ArrayList<> child objects?
* Try using the Async API
* I couldn't find any obvious way of improving JDO write speeds
I'd really appreciate some direction so I don't waste my time trying a
thousand solutions. Any advice would be awesome!
Thanks,
Chad
P.S. My data structure is as follows (abbreviated code):
Parent{
String key; // String key
ArrayList<GameData> gameData;
ArrayList<UserData> userData;
}
GameData{
private Key key; private int itemType;
private int item;
private float ...;
private float ...;
private int ...
private int ...;
private int ...;
private long ...;
private int ...;
}
UserData{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
private int ...;
private String ...;
private long ...; private boolean ...;
}
