I have a main database that runs on a server with good resources and, let's say, a dozen satellites that replicate data. Satellites have less resources than main server.
In that database there is a BIG table, that I want partitioned in ranges because in fact each satellite cares about his own specific range.
PARTITION BY RANGE( ID ) (
PARTITION p0 VALUES LESS THAN (1000000),
PARTITION p1 VALUES LESS THAN (2000000),
PARTITION p2 VALUES LESS THAN (3000000),
PARTITION p3 VALUES LESS THAN (4000000),
PARTITION p4 VALUES LESS THAN ...
);
Let's say satellite 1 cares about table IDs that start with 1, satellite 2 cares about IDs that start with 2 and so on. (all IDs are numbered in millions).
Is it possible to replicate on each satellite only data that are relevant to the satellite? I mean I don't want p2 and p3 on satellite 1, only p1 is relevant for satellite 1. But I don't know how to say to the replication engine that I want only such a part of the data.
Is it only possible to replicate only one partition of the partition scheme?
