cursor

问题 I asked a very similar question here but I need more advance query now. The situation is, we have about 20,000 records of customers. Customers can renew and we just create a new record for it. There is no exact tracing back to which record was actually renewed. Now we have added the old ID field and I want to populate it with the exact old record. Now if it is renewed one time, that has been taken care of my old question and I can do it. The problem is if a record was renewed 3 or more time,

问题 Using ArangoDB 2.3.1. It seems my cursors are expiring within a couple minutes. I would like them to last for an hour. I've set up my AQL query object with the TTL parameter as follows: { "query": 'removed actual query', "count": true, "batchSize": 5, "ttl": 3600000 } My understanding is that the TTL parameter should tell the server to keep the server for 3600000 milliseconds or 1 hour. But it expires within about 60 seconds. In fact, I've tried changing the TTL to several different numbers
