request for a cli flag to the analysis server to moderate memory usage

[devoncarew]

Hi! As discussed w/ @scheglov and @bwilkerson previously:

We'd like a command-line flag for the analysis server to moderate its memory use. The intended use of it would be for the dartpad backend. Its running in a container environment; some useful details:

• we have a fixed size of the memory for the container; less memory usage means we could run more instances of the analysis server. this would help with scaling the backend
• the file system is ram based, so any writes to disk take up memory (this is relevant in the context of the summary / byte store)

The flag might do something like disable the byte store (currently set to max of 1GB I believe?) and reduce or eliminate the summary memory cache? But generally, it would be useful to have a lower memory mode (and no disk cache mode) for use by dartpad.

What's the priority of this?

Hmm, probably modest. It's not blocking anything currently; it would be useful for us when considering any architectural refactoring for dartpad. It would slightly reduce the amount of resources the dartpad backend is using currently, and I expect would have a bigger impact w/ a more stateful backend.
