If we don’t hear any objections by Dec 30th, we will move forward with the plan to no longer generate this data.

Hi all,

Soon, we will be merging the mobile web cache requests with the text cache requests.  text caches will now serve requests for mobile web[1].

This means that the webrequest_source=‘mobile’ partition in the webrequest table in Hive will soon be empty, and all data that was previously in it will be found in the webrequest_source=‘text’ partition.

There are only 3 datasets that currently only use the webrequest_source=‘mobile’ partition:

- /a/log/webrequest/archive/mobile
- /a/log/webrequest/archive/5xx-mobile
- /a/log/webrequest/archive/zero

(These are paths on stat1002, but they also exist in HDFS.)

These datasets originally came from udp2log, but since early last year they have been generated from Hadoop.  With the upcoming cache merge, these jobs will have to parse through all text requests, which will make Hadoop busier.

Do we know if these are being used?  Would anyone be upset if we no longer generated these datasets?

Thanks!
