if memcache and valcache properties are both set for a peer does it prefer one? does it use both? maybe fetch from valcache only if memcache misses?

@rboyd you should only use one or the other, using both valcache and memcached is not supported

ok thanks

is there a way to warm the cache with the entire index+log?

Run large queries

Or walk indexes with the datoms api

Hello, I struggle to find how to query against a collection. Something like this (just to show the intention):

(d/q '[:find ?e
       :in $ ?names
       :where [?e :user/team (in-collection ?names)]]
     db
     #{:foo :bar :baz})

@dam You can bind inputs to collections and tuples (https://docs.datomic.com/cloud/query/query-data-reference.html)

(d/q '[:find ?e
       :in $ [?name ...]
       :where [?e :user/team ?name]]
     db
     #{:foo :bar :baz})

Oh great. Thanks. My brain fits a bit more to Datalog than 10 min ago.

Is there any guide about connecting websocket gateway api with ions?

I was doing the datomic cloud setup week ago, and I was able to get all working and running, but now Im hit with error that I didn't get before when I'm connecting with client api (def client (d/client config)) the socks is running on a given port as systemd service.

ah nevermind, I think this is an old story of root -> user conflict with using systemd
