ES Version: 7.4.2  
Steps:

1. create index and post some data:  
PUT logs  
{  
"settings": {  
"number\_of\_shards": 2,  
"number\_of\_replicas": 1  
}  
}

2. freeze the index  
POST logs/\_freeze

3. try to reindex this index  
POST \_reindex  
{  
"source": {  
"index": "logs"  
},  
"dest": {  
"index": "logs-new"  
}  
}  
step3 does not create index named "logs-new", and response with following:  
{  
"took" : 0,  
"timed\_out" : false,  
"total" : 0,  
"updated" : 0,  
"created" : 0,  
"deleted" : 0,  
"batches" : 0,  
"version\_conflicts" : 0,  
"noops" : 0,  
"retries" : {  
"bulk" : 0,  
"search" : 0  
},  
"throttled\_millis" : 0,  
"requests\_per\_second" : -1.0,  
"throttled\_until\_millis" : 0,  
"failures" :   
}

i tries to add "ignore\_throttled=false" to the url "POST \_reindex?ignore\_throttled=false", but es complains about illegal argument,  
"reason": "request [/\_reindex] contains unrecognized parameter: [ignore\_throttled]"

how can i reindex from an frozen index ?

I don't think that's supported, although it looks feasible to support since frozen indices do support scrolling. Today your options are either to do the reindex "manually" with a scroll or else unfreeze the index while you're reindexing it.

i think maybe es reindex api should support "ignore\_throttled" parameter.  
that's a good solution for reindex from frozen indices?
