besides datomic console, are there any notable tools to analyze/report on my database? specifically I'd like to understand how my db is growing or which entities account for the most used storage

Could someone explain to me how to transact entities with components using the client API? I seem to have a critical hole (or two) in my understanding.

{:db/ident :booking/rrule
 :db/cardinality :db.cardinality/one
 :db/valueType :db.type/ref
 :db/isComponent true}
{:db/ident  :rrule/frequency
    :db/cardinality :db.cardinality/one
    :db/valueType :db.type/long}

When I try transacting

{:booking/rrule {:rrule/frequency 1}}

But when I transact

{:booking/rrule {:rrule/frequency 1 :_booking tempid}}

what is the schema for :rrule/attr

https://github.com/cognitect-labs/day-of-datomic-cloud/blob/b4103e4a8f14518ed3f6d7f66f56cbf863117974/doc-examples/tutorial.clj#L100 is an example of transacting several component entities

Ok, I looked that over and thought that

{:booking/rrule {:rrule/frequency 1}}

Do components have to be wrapped in a vector even if :db.cardinality/one?

I don’t believe so

Or are components required to have unique ids aside from :db/id?

try adding :db/id "foo" to the inner entity

Should “foo” refer to the parent :booking entity tempid?

it shouldn’t “need it” but i’m wondering if there is an edge case here

no, a random tempid

do you have a parent entity tempid?

if that’s a truncated ^ version of your transaction, can you share the full thing please?

Here’s the full transaction:

{:booking/duration "PT1H", :booking/recur-set {:recur-set/rdate [], :recur-set/exdate [], :db/id "bar"}, :booking/student 60842575434612841, :booking/studio 16958867346817130, :booking/dtstart #inst "2015-04-06T21:30:00.000-00:00", :db/id "de92a84f-257c-47b9-bb14-6059bc534c4f", :booking/rrule {:rrule/frequency 1, :rrule/interval :rrule.interval/weeks, :db/id "foo"}, :booking/dtend #inst "2015-04-06T22:30:00.000-00:00", :booking/status :booking.status/scheduled, :booking/instructor 41539549297377384}

and :booking/duration is db.type string?

Yes

rrule and recur-set are cardinality 1?

Yes

If I remove :booking/rrule and :booking/recur-set the transaction succeeds

if you leave either one it is still an issue?

Yes, I have to remove both

If I replace the :db/id in the recur-set and rrule with the parent db/id it succeeds, but then I get faults when querying those attributes

right

try making them “unnested” for testing:

i would try leaving one of the 2 components in (rrule or recur-set) and then remove one attr at a time from it

see if you can narrow it to a specific one

this is almost always caused by either type mismatch or cardinality issue

Ok, makes sense. I’ll see if I can get a minimal case

But, nesting a map for a component like this is supported?

it should be

i’m testing it also

Ok, this works:

@dogenpunk ^ seems to work fine

Could somebody help howto setup datomic cloud lambdas and logging?

I tried lambda-logging together with clojure.tools.logging but I don’t find any documentation howto bring it to work.

@marshall Thanks, I’ll dig in more.
