Re: Backup & Restore of Janusgraph Data with Mixed Index Backend (Elastisearch)

Yeah, good point, it's a bit hairy. Having potentially inconsistent index backups makes them much less attractive. Though I guess I could run a reindex job on just the delta since last Scylla write time and last ES write time. As a simpler alternative, how about pausing write transactions for say ~1s and initiating simultaneous backups of my Scylla and ES clusters during that time? From what I can tell, both backup mechanisms guarantee snapshot isolation. A short write pause should ensure that all writes have propagated. What caveats do you see with this approach? ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐
