Always pass exported functions to Ra queries

I have second thoughts on the fact that MFAs are good enough as a solution to execute code remotely. Yes, with the current patch, we ensure that a query won’t...

khepri_machine: Add command deduplication mechanism

I need to bump the state machine version and convert the state.

khepri_machine: Add command deduplication mechanism

I pushed an additional commit to implement that option that lets the caller decide if it wants the tree to be copied to be able to do nested queries. I...

Add a batch API to push many serial puts/deletes from a single process

I just updated the issue description with the current state of the API I'm working on. Like the regular and transaction APIs, the batch API would offer both simple (`khepri_batch`)...

Passing `fun()` to `ra:*_query()` may break when executed on a remote node

After putting more thoughts into this, I believe the problem is larger. In fact, there are two problems. 1. The validity of a function reference on a remote node 2....
