Titan 0.5.4 -> Titan 1.0 compatibility #32

Closed sayrer closed 8 years ago

sayrer commented 8 years ago

If there is an existing Titan 0.5.4 DB stored at Amazon, what is the migration path to Titan 1.0?

sayrer commented 8 years ago

To be clear, I'm looking for information on storage-compatibility with Titan 0.5.4 / DynamoDB. I understand that the API had breaking changes.

As it turns out it's not compatible, and moving from 0.5.4 to 1.0 requires a backend migration. Going to attempt to see if this approach will work with the dynamo backend: https://github.com/dkuppitz/openflights

The storage formats are not compatible. I asked this question prior to the 1.0 release here: https://groups.google.com/d/msg/aureliusgraphs/A53p9ZG_k30/bSpGtXyKBAAJ

I think using dkuppitz openflights is a great idea.
