Hi Everyone,

Im a newbie with ES and I just have some general questions (I’m just looking for advice)

- Current Installed ES version  
Version: 5.2.2  
lucene\_version: 6.4.1

1. Version Question

- Im looking at upgrading ES from 5.2.2 to version 5.5.3, would anyone advise against 5.5.3 version ?  
(I do prefer to stay a few versions behind the latest release)

1. Index Size / Shards Configuration

"Test-index" : {  
"settings" : {  
"index.analysis.analyzer.phonetic\_analyzer.filter.3" : "stop",  
"index.analysis.analyzer.phonetic\_analyzer.filter.4" : "unique",  
"index.number\_of\_shards" : "5",  
"index.number\_of\_replicas" : "1",  
"index.version.created" : "190899"  
}

- Current Index Size and Doc

“Test-index" : {  
"index" : {  
"primary\_size" : "4.5gb",  
"primary\_size\_in\_bytes" : 4852459028,  
"size" : "8.8gb",  
"size\_in\_bytes" : 9525635793  
},  
"translog" : {  
"operations" : 144  
},  
"docs" : {  
"num\_docs" : 1016496,  
"max\_doc" : 1166314,  
"deleted\_docs" : 149818  
},

- A maximum growth of 2Gig within the next year

Question

- As you can see we are only using a small index, I would like to implement 1 shard and 1 replication for “Test-index” instead of 5 shards (default) what I believe is an over kill for current size and the number of docs.. When performance testing 1 shard with 1m docs the results were excellent (reindexing speed and query response time)

Any input would be great or tips

Cheers

Reid

I understand you don’t want to try 6.0.0 but really latest 5.x version is probably more stable, more secured, more .... than 5.5 🙂  
So I’d go for latest 5.6.  
Be aware that there won’t be any 5.5 update but there will probably some 5.6 updates.

1 shard for your index is probably enough indeed.
