maxDataSize if set to auto the default is 750 MB and 10GB on 64 bit and 1GB on 32 bit hosts, if it is set to auto_high_volume, is that correct?
frozenTimePeriodInSecs = 8640000
maxWarmDBCount = 50
maxHotBuckets = 55
maxDataSize = auto
So going by the configuration for this index , the calculations would come to around (50+55)*750MB = 76GB, also even if we go by 10 GB it would come to (50+55)*10GB = 1050GB for searchable data.
monthly usage for this index, equates to 2906.571GB, if we go by (default 10GB bucket size) then searchable data would be just 1050 GB that does fit the observed two week retention.
how much would we need to increase the maxWarmDBCount to? To allow for Data to be searchable still for 100 days?
