1. GigaSpaces does not use a database for its operations. GigaSpaces implements its own data managment system with indexes where both data and indexes stored in memory.
You can persist the data into a database (any database) or load data from the database into GigaSpaces. See:

2. If you shut down the space you can re-load the data from the database using the ExternalDataSource initial load. See:

3. You can persist the data into any media by implementing the ExternalDataSource interfaces. See:

4. GigaSpaces provides In-Memory-Data-Grid. The system performance would be impacted with slow CPU or Netowrk. See more:

5. Yes. You can load data from Multiple sources and persist into different sources.

6. See the petclinic example provided as part of the openspaces project and the cloud tutorial.

7. See the secutiry section in the docs: http://www.gigaspaces.com/wiki/display/XAP7/Security

8. Make sure you protect the machines and run the system with backups spaces. You might want to have few extra machine available and have GSC started on the fly when needed (by having the GSA running). See:

9. I suggest you to use the Native Space API instead of the JDBC API. See:

Any case, You can update data within the space using the regualr JDBC calls. See:
If the data within the space persit into a database via the Mirror , in case the database transaction fails , the spaec will retrasmit the operation again back into the Mirror.
