Description
What is the bug?
When we use percentile aggregation but no input, it will return 0 instead of null.
How can one reproduce the bug?
Create a index with two items
POST /demo/_doc
{
"demo1": 1,
"demo2": 1
}
POST /demo/_doc
{
"demo1": null,
"demo2": null
}
Then call calcite
POST /_plugins/_ppl/
{
"query": "source=demo | stats percentile(demo1, 50) by demo2"
}
It returns
{
"schema": [
{
"name": "percentile(demo1, 50)",
"type": "long"
},
{
"name": "demo2",
"type": "long"
}
],
"datarows": [
[
0,
null
],
[
1,
1
]
],
"total": 2,
"size": 2
}
Here we return 0 for the bin when demo2 is null. But actually no any input here. So we should return null. 0 has quantitative meanings .
What is the expected behavior?
Return null
What is your host/environment?
- OS: [e.g. iOS]
