Hi All,
As a part of feed ingestion we do allow preprocessing incoming data with AQL
UDFs.
I was wondering if we somehow restrict the kind of UDFs that could be used? Do
we allow joins in these UDFs? Especially joins with the same dataset, which is
used for intake. Ex:
create type TweetType as open {
id: string,
username : string,
location : string,
text : string,
timestamp : string
}
create dataset Tweets(TweetType)
primary key id;
create function feed_processor($x) {
for $y in dataset Tweets
// self-join with Tweets dataset on some predicate($x, $y)
return $y
}
create feed TweetFeed
apply function feed_processor;
The query above fails in runtime, but I was wondering if that theoretically
could work at all.
Best regards,
Ildar
