Back in May, we announced that ScriptDB, an experimental database in Google Apps Script, would be turned off on November 20, 2014. Hopefully you've already migrated your data to another database, but if not, now is the time to check out alternatives like Cloud SQL. The migration guide explains how to export your data from ScriptDB.We’ve also improved the documentation for connecting to external databases through JDBC, makingit easier for you to set up Cloud SQL with Apps Script.
To summarize: ScriptDb will shut down on November 20, 2014, so please ensure you migrate your scripts before then!
