Hi,

This is not urgetn, but if anyone is interested in troubleshooting a (probably basic) problem I am having with mysql, I would appreciate it!

I am trying to query the MobileWebClickTracking table, which is ginormous and keeps timing out or boiling my RAM So Dario suggested I use screen to dump a section of the table into a more workable table.

Here is his test query that seemed to work:

screen mysql -h analytics-store.eqiad.wmnet -B -e "CREATE TABLE staging.jkatz_foo SELECT * FROM enwiki.user LIMIT 300;"

I tried to do this on my own (I use analytics-slave instead, as my credentials don't seem to work on analytics-store), and it doesn't seem to do anything. Can you try on your end and let me know if you're having any luck?

Here is the query:

jkatz@bast1001:~$ screen

jkatz@bast1001:~$ mysql -h analytics-slave.eqiad.wmnet -u research -pJoFjnA90Ajyp -B -e "Insert into staging.jkatz_clicktracking1 Select * from log.MobileWebClickTracking_5929948 WHERE ('timestamp' between 20141101000000 and 20141130000000) and wiki like 'enwiki';"

When I look in processes in stat1003, I only see a sleep command--no query:

Is the query within that sleep? Anyway, I seem to be creating tables but they do not have any rows in them. I have double checked that the data between those dates exists in that table.

Any thoughts?

Best,
