```
public static String PERCENT_MEMORY_PER_QUERY_KEY
```
    Alternative way to compute per-query-per-node memory as a percent of the total available system memory.
    Suggestion for computation.
    - Assume an allowance for non-managed operators. Default assumption: 50%
    - Assume a desired number of concurrent queries. Default assumption: 10.
    - The value of this parameter is
      (1 - non-managed allowance) / concurrency
    Doing the math produces the default 5% number. The actual number given is no less than the max_query_memory_per_node amount.
    This number is used only when throttling is disabled. Setting the number to 0 effectively disables this technique as it will always produce values lower than max_query_memory_per_node.

```
public static final String GRACE_PERIOD
```
    Boot-time config option provided to modify duration of the grace period. Grace period is the amount of time where the drillbit accepts work after the shutdown request is triggered. The primary use of grace period is to avoid the race conditions caused by zookeeper delay in updating the state information of the drillbit that is shutting down. So, it is advisable to have a grace period that is atleast twice the amount of zookeeper refresh time.
