The guidance Splunk gives for estimating size on for syslog data is 50% of original data size. An individual tsidx file may be smaller than the bloom filter file, but as you end up with more buckets, the number of tsidx files will increase, and may end up consuming more space than the bloom filter. 6 Using tstats to search accelerated data models. These optimizations are encapsulated in levels, with new levels added in higher releases of Splunk Enterprise. A retention policy for an index's TSDIX files is available in Splunk Enterprise 6.

The cache manager attempts to defer eviction of the non-journal and non-tsidx bucket files, such as the bloomfilter file, until the interval between the bucket's latest time and the current time exceeds this setting. Because it searches on index-time fields instead of raw events, the tstats command is faster than the stats command.
