[GitHub] [pinot] MeihanLi opened a new issue, #10691: Unable to create Star-Tree index for DISTINCTCOUNTBITMAP
MeihanLi opened a new issue, #10691:
URL: https://github.com/apache/pinot/issues/10691
We recently came into issues when creating star tree index for DISTINCTCOUNTBITMAP. BaseChunkSVForwardIndexWriter can not be initialized because the chunk size is larger than Integer.MAX_VALUE and this checking is introduced by #8286. And We are able to reproduce the issue on a table with only one small segment.
Does anyone know why forward index are created (BaseSingleTreeBuilder: createForwardIndexes) in the process. And is this considered a bug/unexpected behavior or something else?
Star-tree index config as below:
```
"enableDefaultStarTree": false,
"starTreeIndexConfigs": [
{
"dimensionsSplitOrder": [
"time_bucket_derived",
"time_bucket"
],
"skipStarNodeCreationForDimensions": [],
"functionColumnPairs": [
"DISTINCTCOUNTBITMAP__active_riders"
],
"maxLeafRecords": 0
}
],
```
columns metadata as below:
```
{
"name": "time_bucket",
"dataType": "LONG"
},
{
"name": "time_bucket_derived",
"dataType": "LONG"
},
{
"name": "active_riders",
"dataType": "BYTES",
"defaultNullValue": ""
},
Cardinality:
time_bucket: 1440
time_bucket_derived: 24
Max length of active riders: 18360
```
time_bucket_derived is configured as:
```
"ingestionConfig": {
"transformConfigs": [
{
"columnName": "time_bucket_derived",
"transformFunction": "dateTimeConvert(time_bucket, '1:MILLISECONDS:EPOCH', '1:MILLISECONDS:EPOCH', '1:HOURS')"
}
],
```
"diskSizeInBytes": 1158298974,
"numSegments": 1,
"numRows": 3260450,
Errors as below:
```

Thanks Jackie. Yes, the largest entry size we saw is ~25M. How many efforts it will take to upgrade to v4 and deprecate the old version?

URL: https://github.com/apache/pinot/issues/10691#issuecomment-1524212793
Is `active_riders` already serialized `RoaringBitmap`?
I think it throws exception because star-tree builder is still using the V2 raw forward index, where the chunk size is calculated based on the largest entry. If the largest bitmap size is larger than 2M, then the chunk size will be greater than 2GB.
To fix this, we want to allow star-tree to switch to higher version of raw forward index. Further more, we might want to consider making V4 the default raw forward index version, and deprecate the old versions from the builder side.

#11744 adds the support for compression, which can unblock this issue. We may consider also adding the raw index version using similar way

Hi @Jackie-Jiang and @MeihanLi
- is this version of raw forward index configured at cluster level, or it table level?
- if we already have V2 raw forward index in a test table, will it be backward compatible to move to V4?
