Hi If I have data (that needs indexing) that I cannot lose, would it advisable to store it only in Elastic Search as the source of truth with 3 copies (2 replicas) ? Reading a little about index corruption and such, my gut feeling is no, but I was wondering if people had any experience with it.

Data can be corrupted irrespective of its store. What's probably more important is the processes and procedures around writing and reading the data. But, being able to easily increase and scale replication is definitely a positive.

FWIW, in addition to replicas, there's an upcoming change to Lucene that will have checksums on index segments and minimize the chances of corruption in clusters -- Itamar Syn-Hershko [http://code972.com](http://code972.com) | @synhershko [https://twitter.com/synhershko](https://twitter.com/synhershko) Freelance Developer & Consultant Author of RavenDB in Action [http://manning.com/synhershko/](http://manning.com/synhershko/) On Fri, Apr 4, 2014 at 12:19 AM, Mark Walkom [markw@campaignmonitor.com](mailto:markw@campaignmonitor.com)wrote: > Data can be corrupted irrespective of its store. > What's probably more important is the processes and procedures around > writing and reading the data. > > But, being able to easily increase and scale replication is definitely a > positive. > > Regards, > Mark Walkom > > Infrastructure Engineer > Campaign Monitor > email: [markw@campaignmonitor.com](mailto:markw@campaignmonitor.com) > web: [www.campaignmonitor.com](http://www.campaignmonitor.com) > > On 4 April 2014 02:34, Anand Somani [meatforums@gmail.com](mailto:meatforums@gmail.com) wrote: > > > Hi > > > > If I have data (that needs indexing) that I cannot lose, would it > > advisable to store it only in Elastic Search as the source of truth with 3 > > copies (2 replicas) ?
