Entity Durability Patterns in Effect Cluster

Understanding how state survives failures - and how to test it.

The Two Durability Concerns

When an entity "dies" (runner crashes, shard reassigned), there are two separate things to worry about:

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

This example shows an implementation of the @oneOf directive proposed here:
https://github.com/graphql/graphql-spec/pull/825.

It requires Python 3.9 and graphql-core 3.1.3 (https://github.com/graphql-python/graphql-core).

Although the directive support can be implemented out of the box when used in a field
definition, its use in input object type definition requires a specific graphql-core
feature custom output types of input object types
(https://graphql-core-3.readthedocs.io/en/latest/diffs.html#custom-output-types-of-input-object-types).

This is not a complaint about Webpack or v4 in any way. This is just a record of my process trying it out so I could provide feedback to the webpack team

Hmm... I don't see any docs for 4.0 on https://webpack.js.org. I guess I'll just wing it. All I need to do is npm i -D webpack@next, right?

+ webpack@4.0.0-beta.2
