Hi, which is the best strategy to implement a sequence when my app has to be deployed on App engine?
Basically, I have a table with more than 100 records and I would like to extract from it 10 random records. I'm just thinking to use a separate table with a counter and the google id from the primary table. Then I will add there a new mapping record every time I will write a new record in the primary table. eg: 1 | table_A_id1 2 | table_A_id2 3 | table_A_id3 100 | table_A_id100. I know I'm going to face an issue if I will delete records from the primary table. Any better strategy? Uolter
