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:
[image: Inline image 2]
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,
J
