描述

A part of Pinots secret sauce for speed are indexes. Is there any info available what index freshness/delay is achievable for newly ingested data / just changed data (upsert) for the different kinds of indexes? on how this could be improved/reduced? On how index updating works for each type?

of course I found

but no overview / table summing this topic up.

研究方向
Review the existing documentation links and related issues (e.g., #6431, #13504) to understand current index freshness information. Then, study the code for each index type (e.g., text, inverted, star tree) to describe update mechanisms. Compile findings into a table or overview section in the documentation.
