A vital difference is that Slony-I extracts replication information (e.g. - determines what it needs to replicate) via triggers on the tables, whereas Mammoth Replicator takes the (quite common in the industry) approach of reading update information out of the transaction logs. There are a number of differences between the approaches, but in the conversations with people at OSCON, it seemed surprisingly common for the similarities to make it seem that when Slony-I was inadequate, Mammoth Replicator would be too. Of course, this particular discussion hasn't extracted enough information about the dissatisfaction to evaluate much of anything... -- output = ("cbbrowne" "@" "cbbrowne.com") http://cbbrowne.com/info/spiritual.html There was a young lady of Crewe Whose limericks stopped at line two. ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
