Home -> Community -> Mailing Lists -> Oracle-L -> question related to partition
Hi All,
I am wondering how other people implement the following. I have a large transaction table in the OLTP database which will get millions of records per day. I then transfer it to the data warehouse via replication. The table in data warehouse is partitioned. Now the table on OLTP side is also partitioned so the purge of old data is just a matter of dropping partition. Is the partition used on the OLTP side an overkill? Someone (a consultant) suggested using two tables and build a synonym to point to one. Then when midnight comes we drop the synonym and point to another table. We can then truncate the previous table. However, I can't afford to lose any transaction during the swtiching of synonym point to one table from another, even though it only takes a second to do so.
Any thoughts?
Thanks.
Rich
