Question 2: distributed database question?# Database - 数据库
c*t
1 楼
I am writing a P2P application which involves database query
of peers' data.
Say, P1 (peer 1) has following rows in table "serve"
abc1
abc2
ddd1
...
...
hundreds if not thousands of entries.
Peer 2 (P2) perform a broadcast query to all peers in a group
and expect to obtain the queries. I used a dumb query like:
SELECT * FROM serve
and P1 would return the entire table to P2. However, later
P2 does the query again, since P2 is interested in updates
of peers' data.
