|`druid.server.http.maxScatterGatherBytes`|Maximum number of bytes gathered from data nodes such as historicals and realtime processes to execute a query. This is an advance configuration that allows to protect in case broker is under heavy load and not utilizing the data gathered in memory fast enough and leading to OOMs. This limit can be further reduced at query time using `maxScatterGatherBytes` in the context. Note that having large limit is not necessarily bad if broker is never under heavy concurrent load in which case data gathered is processed quickly and freeing up the memory used.|Long.MAX_VALUE|
