Generally, the problem is that I don’t find a way to automatically create a
JDBC table in the JDBC database when I want to insert data into it using Spark
SQL only, not DataFrames API.

I have a resultset (defined in SQL), and I want to insert it into my JDBC
database using only SQL, not dataframes API.
If the table existed, I would create a table using JDBC in spark SQL and
then insert into it, but I can't create a table if it doesn't exist in JDBC
database.
How to do that
Hello.
We’re successfully exporting technical metrics to prometheus using built-in
capabilities of Spark 3, but we need to add custom business metrics as well
using python. Seems like there’s no documentation for that.
Thanks.
Hi guys.
Is there a more lightweight way of stream processing with Spark? What we
want is a simpler way, preferably with no scheduling, which just streams
the data to destinations multiple.
We extensively use Spark Core, SQL, Streaming, GraphX, so it's our main
tool and don't want to add new
, like, if a persisted block is lost or otherwise
unavailable later.

Hi guys.
Basically, we had to define a UDF that does that, is there a built in
function that we can use for it?

Hey Jeffrey.
Thanks for reply.
I already have something similar, I use Grafana and Graphite, and for
simple metric streaming we've got all set-up right.
My question is about interactive patterns. For instance, dynamically choose
an event to monitor, dynamically choose group-by field or any sort
