Does someone know if you can do online upgrade of elassandra? With lucene plugin you cannot really because you need to drop and recreate indexes if lucene has been updated. Hannu > Octavian Rinciog kirjoitti 1.8.2018 kello 12.49: > > Hello! > > Maybe this will work?

Re: Secure data

2018-08-01 Thread Ben Slater
My recommendation is generally to look at encrypting in your application as it’s likely to be overall more secure than DB-level encryption anyway (generally the closer to the user you encrypt the better). I wrote a blog on this last year:

Ben has a good point here. There's an advantage to encrypting in the application, you can encrypt data per-account / user / [some other thing]. It's possible to revoke all access to all the data for a particular [whatever] by simply deleting the encryption key. Lots of options available. On

You might have more luck trying to analyze at the Java level, either via a (Java) stack dump and the "ttop" tool from Swiss Java Knife, or Cassandra tools like "nodetool tpstats" On Wed, Aug 1, 2018 at 2:08 AM, nokia ceph wrote: > Hi, > > i'm having a 5 node cluster with cassandra 3.0.13. > > i

(My advice stands, I still believe it to be safe in all modern versions not impacted by 13004, but) There’s little difference between adding columns and removing columns - if you’re afraid of writes while you add columns, you should be afraid of writes while you remove columns. (But I don’t

Thanks for all the inputs! We’ll stick to the current approach then. How about dropping columns - If we also stop writes beforehand, we should be safe from data alignment issue after dropping columns? Thanks, Li > On Jul 31, 2018, at 04:14, James Shaw wrote: > > in a heavy transaction PROD
