What does 'Non-persistent' mean with Heroku's Redis To Go Nano plan?

Question

I recently signed up for Heroku's Redis To Go https://addons.heroku.com/redistogo. For now, I'm using the free Nano plan, which says:

• 5 MB Redis Instance
• 1 Database
• Non-persistent
• No Backups
• 10 Connections

I get what 'No Backups' etc. mean, but can't find any info on what is 'Non-persistent'? Does it mean the data is wiped out every time I deploy? Daily? Every now and then? When Heroku crashes?

Answer 1

Non-persistent means that your data will disappear if a restart of your instance is needed
e.g. Server issues caused by AWS usually involve instance restarts.

The other plans all provide AOF persistance and daily snapshot RDB backups of your data.
The Direct plans are 30% cheaper and you get more features.

Thanks! The data has been there for 3 weeks already and hasn't been wiped away yet :) – Enlarger

I can tell you what it DOES NOT mean. If you restart from the RTG dashboard, you DO NOT lose data. At least I can attest that I have restarted several times and the data was not lost. So maybe it's exactly as Morgan says, the data will be lost when/if the AWS instance (VM) restarts. – Dermal
