Are requests for documentation updates handled through JIRA?

jaret15:02:23

You can ping me or ship them into <mailto:[email protected]|[email protected]>. Probably best to use the e-mail as it would generate a case that the whole team could see.

Great, thanks!

I'm trying to use REBL with datomic, but the navigation into :db/id just shows an integer. I'm using com.datomic/client-cloud {:mvn/version "0.8.71"}. Am I missing something?

lilactown17:02:21

AFAICT nav support hasn't landed for datomic yet

lilactown17:02:30

could be wrong. but i also couldn't get it to work

johnj16:02:46

If you need an email entity :email/address :email/type and a generic attribute to reference it, what would you call it? :email/emails ?

Using delete-database on datomic cloud does not seem to remove the datoms, is this normal? Shouldn't it?

marshall18:02:28

If you mean datoms as reported in the dashboard under the Datoms metric, they will be cleaned up, but not immediately.

marcol18:02:16

Actually I meant more the data that seems to remain in DynamoDB that is associated to the deleted database

marshall21:02:52

Those segments will get garbage collected at a future point, but not immediately

marcol00:02:56

Perfect, Thanks for the answer!

is there any way to show the “query plan” in datomic cloud? It would be nice to see how the query will be executed against the indexes if only to get a better sense of how to put queries together. I may be thinking about this the wrong way, but I’ve always found the “explain” functionality of traditional RDBMSs to be quite useful in practice.

favila18:02:58

It’s not very elaborate

favila18:02:12

For eg clauses are never reordered

favila18:02:03

There was a third party query explainer. Third party was possible because the optimizations are very simple

favila18:02:16

There is none built in

okocim18:02:17

cool thanks. I a third party one here: https://github.com/dwhjames/datomic-q-explain which should be simple enough to adapt for the client api. appreciate the help

okocim18:02:13

looks like this doesn’t handle the parsing the queries very well for things like (or-join) and (and) etc. 🤷

favila19:02:34

those are new features

favila19:02:40

probably didn't exist when it was written

favila19:02:51

they are just sugar for rules though

favila19:02:57

you can rewrite as rules
