Is scalar index (e.g. Inverted Index) loaded in memory?

[pycui]

When calculating the memory requirement of query nodes, how to properly consider the scalar indexes? Can we add more documentation on this? thanks

Scalar index is loaded into memory.
The document already shows how to estimate scalar index size: https://milvus.io/docs/scalar_index.md

with latest 2.4.10, you can enable mmap for some of the inverted index.

@SimFG
do we have a document for that?
