Question

I have been looking through the new ScriptDb functionality – I am sure it is ‘better’ than Fusion Tables as a data store, I am just not sure how/why? Would anyone be able to suggest why it would be preferable (although not universally so, I am sure) over a Fusion Table?

Answer 1

Here are few points to justify “why use scriptDB”

1. You do not have to use URLfetch to fetch data from Fusion Tables. Since you have relatively lower quota (as per my observation) for URLFetch
2. ScriptDB is natively supported in App Script so it is faster and robust than your own implementation to access fusion tables.
3. ScriptDB is key-value store (in the form of JSON) whose latency increases linearly as the DB size increases which is faster than all RDBMS whose latency increases exponentially with DB size. But I am not sure how Fusion Table behave as data size increases.
4. ScripDB service has far higher quota than URLFetch.
5. You can do maximum 5 queries in a second in fusion table but in scriptDB, there is no such declaration of query limit.
6. size limit of ScriptDB:
   50MB for consumer accounts,
   100MB for Google Apps accounts,
   200MB for Google Apps for Business/Education/Government accounts,. I think, this is sufficient for application developed using Apps Script.
