Dose Community Edition support Automated Snapshots?

I saw the document (https://github.com/benjaminballard/voltdb_docs/blob/master/training/ex_cli_03_commandlogging.md) ,there is "VoltDB Community Edition does not include command logging, so it has a feature called Automatic Snapshots."...
But when i try it, voltdb show some error message like "ERROR: Snapshots are not supported in the community edition of VoltDB."
So, Dose Community Edition support Automated Snapshots?

Hi tanker,

That document was one that I wrote for use in some in-person training sessions more than two years ago for VoltDB v3.0 and earlier. It is now quite obsolete. Automated snapshots are no longer available in Community Edition.

I would recommend you download Enterprise Edition from voltdb.com and use the free trial license so you can test all of the enterprise features. Then rather than following that outdated document, you could follow the Tutorial and refer to the appendices in Using VoltDB for syntax, and the sections in the Administrator Guide for how to perform operations like recover from command log, rejoining a stopped node, etc. These are online at http://docs.voltdb.com.

Kind regards,
Ben

Hi, bballard

Thank you very much!

And is there any way to achieve disk durable (or Data persistence)?

I just want to save data from memory to disk:)
