I have multiple DBs in a multiple threaded application, meanwhile, it's on TDS, and I'd like to enalbe each DB to increment its key automatically, what question should I be careful?
1. create sequence db for each its caller DB?
2. wrap sequence db->get like this?
key = sequence_db->get;
put data into main db with key;
or abort transaction
can I rollback to retry if something exception happens?
