I have tried below sample search for acceleration but they are not allowed.
index="_internal"| table host source
index=_internal|streamstats sum(bytes) as byte by sourcetype|stats count by host source byte
as per splunk docs, it should contain transforming commands and I hope table is transforming commands. so first query should be able to accelerate but it won't accelerate. Can you please help me to understand why those searches are not allowed to be accelerated?
