>
> large queries are very expensive than the general operation, and often delay insensitive.
> if not isolate, Handlers may be all used by the large query,
> lead to _Put_ or _Get_ slowly, so there need be an mechanism to isolate the large query.
> for example we can use a separate _RpcExecutor_ to handle this.
> for the following type of queries we can think it is a large query:
> (1) _Scan_ has no startkey or endkey
> (2) Client call _ResultScanner.next()_ more than a certain threshold
> (3) Client call custom coprocessor which involves large queries(such as _AggregateService_)
> for large queries, RegionServer should meet the following requirements
> (1) dynamic configure if isolate large query is turn on
> (2) setup certain Handlers to deal with large queries only
> (3) in offpeak hours, large queries are not isolate
> (4) dynamic configure if cache Blocks is turn on if the query is a large query
