Does msal4j supports high availability as in msal.net?

[xiaozhon]

Hi team, I found that msal.net supports high availability through different mechanisms: https://learn.microsoft.com/en-us/entra/msal/dotnet/advanced/high-availability. I didn't find a similar doc for msal4j, so I am posting this issue to ask: does msal4j support similar high availability?

Hi @xiaozhon - it supports several mechanisms, but not all.

• it supports external token caching, but we don't have samples showcasing this well, except for public client desktop and client_credentials

Note that MSAL Java's default token cache is not scalable, it is ok for a few 100 token entries, but no more. Apps are supposed to use distributed token caching or have 1 CCA object per session to get around this.

• no monitoring, but @Avery-Dunn is working on getting the TokenSource out
• no default retry policy (this is probably for the best, SDKs should not have retries)

The rest of items like logging, proactive token refresh are there.

What sort of app do you need to write?
