Does in refresh interval data of the entire shards get changed or only the data which has been changed.
Suppose
refresh interval is **1s**.
And in if **index.requests.cache.enable = true** then filter query results will be cached .
So will refresh interval will flush all the data from cache or only the data which has been changed

The refresh interval does not relate to the request cache.
From [the docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/indices-refresh.html);
> A refresh makes all operations performed on an index since the last refresh available for search.
An operation means an index (write), delete or update.

Please have a look at this. In Cache Invalidation it is mentioned the caches clear's as soon as the shard gets refreshed

You're right sorry, I forgot that also happened.
So every time a refresh happens, it invalidates that cache.

So it invalidate's the entire cache or it invalidate's only the documents which are updated
