How to bound the memory usage of the metadata within v2.7?

I got big number of series to manage and limited memory to utilize.

Since TSI file could help to store the metadata(like measurement, tags, …) on disk, I want most of my memory be utilized for data operations.

The question is, is it possible to bound the memory usage of metadata ? i.e., only cache as little as possible metadata while leaving most of them on the disk.

I have tried to configure storage-series-id-set-cache-size, but nothing really happend.

Any help and hint are sincerely appreciated. Thank you for your patience.
