Rahul Challapalli updated DRILL-1810:
-------------------------------------
Description:
git.commit.id.abbrev=4a4f54a
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}
I attached the log files. Let me know if you need anything
was:
git.commit.id.abbrev=4a4f54a
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
