> Memory Settings
> {code}
> DRILL_MAX_DIRECT_MEMORY="32G"
> DRILL_MAX_HEAP="4G"
> {code}
> Scalar Dataset :
> {code}
> {"col1":{"a":"b"}}
> {code}
> The below query works fine for the above data set. However, if I just copy the same record 100000 times and execute the same query, kvgen fails with memory related issues
> {code}
> select kvgen(col1) from `json_kvgenflatten/kvgen-scalar-large.json`;
> {code}
> Complex Dataset :
> {code}
> {
> "data" : {
> "col1" : {
> "one" : [1,2,3,4],
> "two" : [{"a":"b"},{"c":"d"}]
> }
> }
> }
> {code}
> Even in this case, the below query works fine for the above data set. However when we copy the same record 100000 times we are hitting memory issues
> {code}
> select kvgen(data) from `json_kvgenflatten/kvgen-complex-large.json`;
> {code}
> I attached the log files for both the scenarios. Let me know if you need anything
