To get the best speed out of SolrCloud you have to index from many clients (or threads). Even better is if you index to many nodes rather than one.
Using a single thread against a single instance with replicas will be a fair amount slower with cloud than if you just used one node. - Mark On Nov 27, 2012, at 12:02 AM, deniz <denizdurmu...@gmail.com> wrote: > As I am some kinda confused, I wanna check if anyone else has same confusions > like mine about solrcloud.. > > I have set up an environment with 3 solr instances and 2 zookeepers, amd > tried to index some documents from mysql db. the total amount the docs are > around 3.5M. before indexing i was expecting some longer time for cloud as > it does replication between nodes, but i am some kinda disappointed after > seeing that indexing took 4 to 5 times higher than indexing on a single solr > instance. on a single solr instance i am able to index those docs around 17 > mins while with cloud it tooks around 60 minutes. and as a possible > production environment will have more instances and machines available for > the cloud, i cant imagine the indexing time... in adiditon to initial > indexing time, we will be updating our indexes frequently, which makes me > sceptical about solrcloud. > > so in a possible production environment with solrcloud, in case there is a > serious failure on some nodes, sync operation on cloud will take long > time... in this case, reindexing everything on a single instance will took > less than 17 mins, which is a reasonable amount of time for a crash.. so in > this case does it make sense use solrcloud although indexing time will > increase much higher than a single instance? or using a traditional master - > slave structure will be better for this case? > > I am aware cloud makes loadbalancing and some other stuff largely concerned > about searching, rather than indexing, but for a frequently updated system, > does it still useful to set up a cloud environment? > > and are there some workarounds for indexing speed, other than the known ones > for solr, on cloud? > > > > ----- > Zeki ama calismiyor...
