Wine supports WoW64 since recently [1]

You can use access policies [1] to emulate temporal data. See an example in [2]

Strictly speaking we charge for compute and storage. You can create variously-sized Gel instances and within those instances an arbitrary number of branches.

The paper seems to mostly focus on the quality of cardinality estimation (mostly driven by statistics) which is admittedly one of the frequent sore points in Postgres. There's been some progress in that area though (CREATE STATISTICS being a highlight).

That's already supported, you just need to set the Postgres cluster URI in the `GEL_SERVER_BACKEND_DSN` env var ([1]).

You can use Docker (and Docker Compose) with Gel for local development [1], but of course you'd miss out on most management features of the CLI, because it's not built to supplant the docker/docker-compose CLI. Are there any particular issues you have currently with the Docker image approach?

> If I use some other extension like timescale is that compatible with gel [...] Postgres is so powerful partly because of its ecosystem, so I want to know how much of that ecosystem is still useable if I’m using gel on top of Postgres

Playing nice with the ecosystem is the goal. We started off with more of a walled garden, but with 6.0 a lot of those walls came down with direct SQL support and support for standalone extensions [1]. There is a blog post coming about this specifically tomorrow (I think).

> And is there a story for replication

Replication/failover works out of the box.

> subscribing to queries for real time updates?

Working on it.

> so can I add gel to an existing Postgres instance and get the benefits of the nicer query language or does it rely on special tables?

Gel is built around its schema, so you will need to import your SQL schema. After that you can query things with EdgeQL (or SQL/ORM as before).

Gel as in gif obviously! :-)

EdgeDB is NOT an object store. It is "relational model enhanced" instead where a set is a fundamental building block [1] so not just relations are sets, but attributes can be sets also.

If your database client is any good, it should do the retries for you. EdgeDB uses serializable isolation (as the only option), and all our bindings are coded to retry on transaction serialization errors by default.

Transaction deadlocks are another common issue that is triggered by concurrent transactions even at lower levels and should be retried also.

Yes. Apache 2.0 licensed with lots of focus on local-first development.

There is a work-in-progress query builder support for .NET: https://github.com/edgedb/edgedb-net/tree/feat/querybuilder-...

> Can EdgeDB solve the problems like `soft-delete`?

Yes, with access policy rules. E.g

   global hide_deleted: bool;

   type SoftDeletable {
     deleted: bool;

     access policy hide_deleted
       allow all
       when (global hide_deleted)
       using (not .deleted);
   }

The above will effectively "hide" objects with `.deleted` set to `true` from all queries when the `hide_deleted` global is set to true.

> How about hooks, for example, I want to trigger scripts after/before a record is added to the table.

EdgeDB supports triggers: https://www.edgedb.com/docs/changelog/3_x#triggers. Future versions will add support for causing effects outside of the database, e.g. call a WebHook or some such.

The whole thing consists of these main parts:

1. SQL parser: https://github.com/edgedb/edgedb/tree/master/edb/pgsql/parse... 2. SQL transpiler: https://github.com/edgedb/edgedb/tree/master/edb/pgsql/parse... 3. Wire protocol handler: https://github.com/edgedb/edgedb/blob/master/edb/server/prot...

No plans for that yet. We feel EdgeQL is a far superior choice for the intended use case of application development.

Yes, although rewrites are fairly minimal. Mostly limited to name mangling.

Yes, we are looking into possibly supporting in-place upgrades in future releases.
