By default, the magento order increment id is 9 digits something like #000000034 and wanted to know what if the order increment id reaches #999999999. So I have edited the table eav_entity_store, updated the increment_last_id value as 999999999 and placed two orders. I got the new increment Ids as 11000000000 and 11000000001. So its clear for me that the order is not stopping at 999999999 and its still growing. However I am not sure about the maximum limit.
Do anyone having any idea on what will be the maximum number of orders can a Magento website hold in its lifetime, since our current store can be filled up with thousands of orders everyday and not sure if it reaches any maximum limit?
