This is probably the wrong list for your question.

And, no, I don't think that your conversion is correct.

To me it looks like you have lots of values in a fmsession.  In the avro
version, those values appear to be repeated in the fmsswitchvalues. That
seems wrong.

Hey Bart,

Why not using Sqoop for trasforming data from/to hadoop to/from MySQL?
http://sqoop.apache.org/docs/1.4.2/SqoopUserGuide.html
see the parameter: -as-avrodatafile

Hi!

I will subscribe to the avro users mailinglist as well for
this, thanks!

I'm not sure that i understand your comment about
repeating values in fmsswitchvalues, since they are different from the
ones in fmssession?

Kind regards,

Bart

Attached you can find the schema i'm converting to Avro, along with the
corresponding Avro schema i would like to use for my imported data. I
was wondering if you guys could go over the schema and determine if this
is sane/optimal, and if not, how i should improve it.

Hey Ruslan,

I'm not using Sqoop because my avro exist of a couple
of subsets, which (afaik) are impossible to reproduce with a single
query and thus sqoop. Or am I wrong?

Kind regards,

Bart
