in Search head, my cluster status shows:  
{  
state: open  
settings: {  
index.compress: true  
index.number\_of\_replicas: 1  
index.number\_of\_shards: 12  
index.refresh\_interval: 10s  
index.version.created: 190999  
}

The index was created like so:  
conn.create\_index\_if\_missing(index\_name,settings={'compress':  
'true',"number\_of\_shards" : 12,"number\_of\_replicas" : 1,"refresh\_interval"  
: "10s",})

Is it the case that all stored fields are now compressed? or do I need to  
specify compression option at the fields/mapping level as well?

Thanks a lot,  
Mohamed.

hey,

see [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/index-modules/store.html)  
(Store Level Compression)

you should use index.store.compress.stored

for this or you if you only want to compress the \_source field you need to  
enable that in the mapping. Yet, store level compression has better  
compression compared to \_source.

Cool thanks a lot. do I still need the first level "compress" field in my  
index creation settings, or is that redundant now?

settings={  
'compress': 'true',  
"number\_of\_shards" : 12,  
"number\_of\_replicas" : 1,  
"refresh\_interval" : "10s",  
"store": {"compress": {"stored": 'true',"tv": 'true'},},  
}
