Is there a way to "un-register" a transactor with a database? i.e. replace the value specified by "host" in sql.properties? also is there a way to query for what the currently configured transactor host is?
transactors actively write themselves into storage continually while they are running. to “un-register”, start a new transactor with different settings.
ok, that makes sense, thanks! is there a way to query for what the currently registered transactor(s) are?
There’s a way that relies on internal implementation details; but, why do you want to do this?
we're just having some deployment issues and wanted to confirm what the current host name is since we recently changed the VNet that the transactor VM is on
sorry, I'm not sure I follow, are ‘pod-coord’ and ‘pod-standby’ entities or attributes? what would that query look like?
IIRC the datomic documentation recommends using db/ident
for enumeration types. Could someone share schema declaration example of this usage? I was trying to wrap my head around how that will work but could not find any code examples demonstrating the usage. Thanks in advance.
Thanks. Found this example: https://docs.datomic.com/cloud/schema/schema-modeling.html
How does a q-seq query compare to a datoms avet index query in terms of performance?
I'm pretty confused at this point. I'm using lein
. I removed my dependency on [com.datomic/client-cloud "0.8.101"]
. I only have a dependency for [com.datomic/dev-local "0.9.180"]
.
I can execute:
(ns db.core
(:require
[datomic.client.api :as d]
[datomic.client.api.async :as d.async]
[clojure.core.async :as async]
[cognitect.anomalies :as anom]
))
(defonce ^:private local-config
{:server-type :dev-local
:system "dev"})
(comment (d/client local-config))
perfectly fine in my repl. But (d.async/client local-config)
throws:
Execution error (ExceptionInfo) at datomic.client.api.impl/incorrect (impl.clj:43).
:server-type must be :cloud or :peer-server
