Hi ! To improve our software insert datas performance, we have decided to use partition architecture in our database. It works well for the following volume : 45 main tables and 288 inherited daughter tables for each, that is a total of 12960 partitions. I have some trouble now with another customer's database with the following volume : 87 main tables and 288 tables for each, that is 25056 partitions. Is there some kind of limit in postgresql about the number of partitions ? Do you know some tuning in the conf files to improve postgresql management of so many tables ? I have already used different tablespaces, one for each main table and its 288 partitions. I have many datas to insert into these tables (that is ten or hundred of thousands every five minutes for each main group). Do you think it can be done with a hardware raid 0 SATA disk (it's the case today ...) ? Thank you all for help. Best regards Sylvain Caillet
