07/08/2025, 8:39 AMeraseDimensionValues in my MergeRollupTask config. I have it set to erase the hostname dimension during rollup, but the values aren't being removed - they still appear in the offline table after the task runs.
My config:
"MergeRollupTask": {
"1hour.eraseDimensionValues": "hostname",
"1hour.mergeType": "rollup",
"1hour.bucketTimePeriod": "1h",
"1hour.bufferTimePeriod": "3h"
}
The hostname dimension has defaultNullValue: "ERASED" in my schema.
Questions:
1. Is eraseDimensionValues available in the current release, or is it still experimental?
2. Should I expect the hostname column to be completely removed, or replaced with the default null value?
3. Are there any logs I should check to confirm the task is processing this config correctly?
My setup: RT data → offline table with MergeRollupTask running on the offline table. Thanks!Povilas Vaitkus
