Re: Validate data consistency after nodetool rebuild

2020-07-09 Thread Jeff Jirsa
Not in 3.11, though 4.0 adds preview repair which can sorta do this if you're also running incremental repair. Just run nodetool repair, use subranges if needed. If you stream data, they're out of sync. If you don't stream data, they're in sync. On Thu, Jul 9, 2020 at 3:16 PM Jai Bheemsen Rao

Validate data consistency after nodetool rebuild

2020-07-09 Thread Jai Bheemsen Rao Dhanwada

You could also pull TWCS out of the version of Cassandra you want to deploy, fix the imports and change the package name. Then you've got the same version as OSS, just under the name you're using in 2.1. Once you've moved to 3.11, you can switch to the OSS version. On Thu, Jul 9, 2020 at 9:09
