Subject Re: Solr on HDFS vs local storage - Benchmarking
Date Wed, 22 Nov 2017 14:16:13 GMT
We did some testing and the performance was strangely even better with 
HDFS then the with the local file system. But this seems to greatly 
depend on how your setup looks like and what actions you perform. We now 
had a patter with lots of small updates and commits and that seems to be 
quite a bit slower. We are about to do performance testing on that now.

The reason we switched to HDFS was largely connected to us using Docker 
and Marathon/Mesos. With HDFS the data is in a shared file system and 
thus it is possible to move the replica to a different instance on a a 
different host.
