RE: relay log one table

[Peter Benjamin Volk]

Hi,

No it is not a bug. Since the Master server never knows what the slave
wants it always transmits everything. The slave then decides if it will
execute the statement or not (depending on the setup). 

If you want to reduce the traffic costs you can either do it with a
scheduler calling LOAD TABLE <table name> FROM MASTER
(http://dev.mysql.com/doc/refman/4.1/en/load-table-from-master.html).
This will only load the data from the specified table. Or you can
upgrade your servers to 5.1 (once it becomes past the Beta stage). In
the new version MySQL changed the replication format from simple
statement based replication to row based replication. This should reduce
the traffic quite a bit.

Subject: relay log one table

i have two hosts with mysql 4.1.21 on different machines.

i have a task to replicate two tables from the master's database called
'masterdb' which consists of several tens of tables.
so i configured master and slave servers according to Mysql
Documentation.


i've set the following options to my.cnf on slave:

server-id       = 2
#replicate-do-db=asterisk
replicate-do-table=asterisk.test_area_price
replicate-do-table=asterisk.non_area
replicate-rewrite-db=masterdb >asterisk

everything just works fine. these two tables is replicating as i wish.

but several days before i  examined slave-relay-bin.XXXXXX on my slave
server and i have found that the slave server made requests to all
statements in whole database 'masterdb' from master server even on that
tables which i do not want to be replicated. every request on every
table from master database was downloaded by the slave to its
relay-bin-log.
is it bug?
here i have very high costs of traffic between these two machines. so
its very expensive to download all database-requests and statements from
master-server to slave I/O thread and slave relay-bin-log. So i need to
find some options which i can pass to the slave server to download only
that requests which are relate to my replicated tables.

is it possible?
thanks in advance.
