Phil Miesle updated CASSANDRA-16204:
------------------------------------
Description:
This seems to be a different issue than Cassandra-14982 :
$ cqlsh --version
cqlsh 6.8.0
Following Datastax Academy course DS220, in the Denormalization exercise. I
received
{code:java}
PicklingError: Can't pickle <class 'cqlshlib.copyutil.video_encoding'>:
attribute lookup video_encoding on cqlshlib.copyutil failed{code}
on the COPY command into the following table:
{code:java}
CREATE TABLE videos_by_actor (
actor text,
added_date timestamp,
video_id timeuuid,
character_name text,
description text,
encoding frozen<video_encoding>,
tags set<text>,
title text,
user_id uuid,
PRIMARY KEY ( (actor), added_date, video_id )
) WITH CLUSTERING ORDER BY ( added_date desc, video_id asc);
COPY
videos_by_actor(actor,added_date,video_id,character_name,description,encoding,tags,title,user_id)
FROM 'videos_by_actor.csv' WITH HEADER = true{code}
Now, as it turns out my PRIMARY KEY was non-unique (noted when I failed to load
as many records as were in the file), and when I changed to:
{code:java}
PRIMARY KEY ((actor), added_date, video_id, character_name){code}
the command worked. BUT the following options also worked (though they both
dropped records):
{code:java}
WITH HEADER = true AND MINBATCHSIZE=1 AND MAXBATCHSIZE=1 AND PAGESIZE=10;{code}
and
{code:java}
WITH HEADER = true AND NUMPROCESSES=1;{code}
So this seems to be a problem of multi-threading and user-defined TYPEs?
I'll note that I'm running inside a WSL2 Docker Container based on
ubuntu:bionic:
