Hi!
1. Is there a unique key for the query log? The
log I am refering to
is the *wdqs_extract* table**from
the hive database wmf.**We would like to be able to
permanently link our own computed data with the log entry we
computed it from.
I think you can use hostname+sequence (from
https://wikitech.wikimedia.org/wiki/Analytics/Data/Webrequest, assuming
those are preserved in wdqs_extract) as a key.
2. Is it possible to find out if a query in a
given log entry was
accepted by the sparql endpoint as valid?
If it wasn't, the result code should be 400.
3. Is there any other database system besides hive
installed on the
server?
I think the currently recommended interface is beeline, not sure about
other DB systems.
And finally a question on conventions for this
mailing list: Am I
correct in sending one mail for multiple questions or should I send
separate mails for each question?
I think it's ok. For the questions regarding data and other WDQS
specifics you may also CC me or discovery(a)lists.wikimedia.org.
