Hi ppl,
What need to do (understand, to devel) to allow several
postgres instance running from several server to access to the
same data (no replication at all) hosted on a SAN ?
I'm probably wrong but i think this type of dev should
be easier to realize than replication ? Because all node are
always consistent since they use exactly the same data ?
In fact i'm asking why opensource db go only to the
replication solution than "true" clustering solution using SAN
like Oracle RAC ? I don't see the big advantage of the replication
method (of course, for application which need more than few nodes
hosting "small" db). The price could be an answer but what about a db of
several hundred giga byte ? When a node is added it must contain this
capacity nearly for "nothing" (i thinks its more and more a waste when
number of node grow ...).
Is this a planed feature ?
Sincerely, Yannick.
