elasticsearch 1.1.0 compatibility? full cluster restart?

2014-03-26 Thread Graham Tackley
The release notes for elasticsearch 1.1.0 don't say anything about 
compatibility with 1.0 (or at least I didn't see it).

- can I mix 1.0.1 and 1.1.0 in the same cluster, i.e. do a rolling upgrade? 
 
- does the java 1.0.1 client library talk ok to a 1.1.0 cluster?

I'm really excited about some of the new stuff in 1.1.0...

Re: Java API or REST API for client development ?

2014-03-26 Thread Graham Tackley
Not true anymore: the java client has been compatible between minor 
versions since 0.90 as far as I remember. 1.0.0 client is currently working 
just fine against my 1.0.1 cluster, and my experimentation today shows that 
it also works fine against 1.1.0.  So this used to be a nightmare requiring 
synchronised upgrades, but hasn't been for a while.

FWIW we use the java client (in transport client mode) extensively from our 
scala apps, and it works brilliantly. I'd definitely recommend.

 The Java API is said to have better performance (and I believe that). The 
 drawbacks are that you must use the exact same version of the java API 
 library on the client as the server runs, as well as the same version of 
 Java. So upgrades suck.
