We have some tests which query the index size from Elasticsearch and perform some validations on it. This validation is flaky - it does not pass always. Below is the reproduction:  
Execute all commands below in one go:

> PUT idx1  
> PUT idx1/t1/1  
> {  
> "name": "foo"  
> }  
> PUT idx1/t1/2  
> {  
> "name": "bar"  
> }  
> POST idx1/\_refresh  
> POST idx1/\_flush/synced  
> GET idx1/\_stats/store,docs,indexing?filter\_path=indices

In the response of the last command, value of `"indices.idx1.primaries.store.size_in_bytes`" is `261`. If I execute the last command repeatedly for a few seconds, it eventually increases and settles at `7793`. Funny thing is if I delete the index `idx1` and execute all the commands above, I get the value `7793` in the very first attempt. If I repeat this with a new index name, the bug reproduces. This leads me to believe there is some caching going on in the background. I want to know if there a way to get to the final state reliably and synchronously instead of polling. Maybe I need to execute more commands. Please help.
