querier OOM

[CheerfulMinions]

The querier component:

Some queries involve a very large amount of data, and I found that the querier would encounter OOM.

(:≡(:≡(:≡ How can this be solved?
(Limiting the size of the queried data, limiting the number of chunks, limiting the number of concurrent requests, etc. These methods are not perfect.)

A couple ideas:

• Try setting GOMEMLIMIT environment variable: see here for more info. I usually set this to 90% of available memory.
• Tune limits as you mentioned
• There is a proposal to distribute queries here, which if implemented will enable larger queries
