Avoid controlling endless loop with exception in loadAnonymousClasses, e.g. by extracting loading class to the method:

  private boolean tryLoadClass(String innerClassName) {
        try {
            parent.loadClass(innerClassName);
        } catch (ClassNotFoundException ex) {
            return false;
        }
        return true;
    }

Sometimes we need to store a reference to an error object somewhere in the code so that we can return it to users. A good example is net.box: if the state machine is in the error state, we should return the error that caused the failure to all user requests. The problem is a user that got an error may link it to another error with [error.set_prev](https://www.tarantool.io/en/doc/latest/reference

Currently we don't have any mechanism to limit the maximum number of clients that could be handled simultaneously.

This feature should be designed properly. Here is some clue: https://redis.io/topics/clients#maximum-number-of-clients

Accessing Slice from Java requires input ByteOps for each API call which is repetitive and no fun.

Slice
  .ofBytesJava(50) 
  .addInt(data.getInteger(), ByteOps.Java())
  .addLong(data.getLongVal(), ByteOps.Java())
  .addStringUTF8(data.getString(), ByteOps.Java())
  .close(); 

See example.

Solution

Maybe

Use of the $geoNear pipeline stage results in:

[Error 40324] Unrecognized pipeline stage name: '$geoNear'

It's clear it is not currently supported in de.bwaldvogel.mongo.backend.aggregation.Aggregation.java

Example Mongo query usage:

db.places.aggregate([
   {
     $geoNear: {
        near: { type: "Point", coordinates: [ -73.99279 , 40.719296 ] },
        distance

Tracking issue

Currently, the Go client does not support Hazelcast's partition predicate.
