Will the maxHotSpanSecs roll my buckets from warm to cold?

[erw550]

Hello,
I am wondering when my index will roll from warm to cold with the settings below, the rest of the settings is default:

[XXXX]
frozenTimePeriodInSecs = 46656000
maxDataSize = auto_high_volume
maxTotalDataSizeMB = 4294967295
maxWarmDBCount = 4294967295
repFactor = auto

Will the default setting maxHotSpanSecs = 7776000 roll the buckets from warm to cold or is it just the span within the bucket?
When will the buckets roll from warm to cold in this case?

Thanks in advance!

Hi

That parameter defines which is the maximum time before hot bucket rolls to warm (unless it has already rolled based on bucket count or restarting splunk).

From warm to cold the rolling is usually done by homePath.maxDataSizeMB or maxWarmDBCount. 

Here is some additional answers + conf presentation about it:
