Hello Arvind,
i worked on MMO (and especially their performance) some time ago. I
really like(d) them. :)
we are all aware of the popular trend of MMO games. where players face
To understand my query, please consider the following scenario
/we store game progress in a postgres table./
A tournament starts with four players and following activity
1. Each player starts with 100hitpoints
2. player 1 makes a strike (we refer to a chart to convert blows to
hitpoints with random-range %)
3. player 2 has 92HP, and returns a light blow, so player1 has 98hp
That is a very simple description or a very simple system.
The above two round will now be in Game Progress Table, as
|ROWPlayer1HP Player2HP Strikefrom StrikeTo ReturnStrikeHP Round TimeStamp StrikeMethod
1 100 100 0 0 0 0
2 98 92 P1 P22 1
|
At this point you should reconsider if you need this much data. It is
faster to store less data.
For example you do not need the colum "ReturnStrikeHP". You can
calculate the damage from the difference between the rows.
If there is a cyclic change of the attacker (P1->P2->P1->P2->P1->P2 ...)
you just need to store the starting player and could drop the "strik
from" and "strike to" column.
If you need it and there are just 2 players in one fight, reduce the
column to "attacker" and store if it is player one or two. The one which
is not in the column is the defender.
Also why do you store each round? Most time there are just reports,
charts or animations about the fight. You can generate them in a more
compact form and just store 1 row with this information. In this way you
will reduce the number of needed INSERT-operations a lot. And you will
speed-up the SELECT because less data must be read.
I hope this will help you. Greetings from Germany,
Torsten
