In V1.79,What is the relationship and logic between TSI TSL TSM and In-Memory Index ?

TSM is the storage engine, it’s a time structured merge tree.

The in-mem index is as it states, it stores the entire index in-mem; which can cause an OOM if it’s too big for your RAM.

TSI is our time series index, which is a combination of in-mem and disk based indices

No matter what index you use, you always get TSM storage.

.tsl files are “time series log” files that are part of the TSI indexing process.
