Re: Killing Cron Process?
I tried Oren's suggestion about doing a heroku restart and that did not kill/restart an already-running cron task. Same with uninstalling the cron addon - that does not seem to kill the already-running cron process either. Any other ideas? Maybe a heroku kill might be in order... -Zach On Wed, Dec 29, 2010 at 1:50 PM, Zach Bailey znbai...@gmail.com wrote: I have a long-running cron process as a result of an out of control task that I need to kill.

Re: Storing logs in a remote server
The advanced version of the Heroku logging add-on allows you to specify your own custom syslog endpoint: http://addons.heroku.com/logging I would recommend contacting someone at Heroku directly to gain access to that so you can capture all the data. This way, you could set up your own dedicated EC2 instance running syslog and capture all the data, allowing you to read and filter it as needed.

Re: logs:cron shows no output
Any updates on this? I'm now having an error in one of my cron tasks and the inability to view the logs as a first line of debugging is causing me a major headache.

Re: Can't seem to install the Taps gem
If you're using rvm, you should never install gems using sudo, as rvm keeps its environment tied to your regular user account. Try gem install taps instead. Then, it should show up when you run gems list HTH, Zach On Thursday, December 9, 2010 at 7:47 AM, Jimmy wrote: I'm trying to use Heroku's Taps gem to get my database from their server.

Re: Best way to DB import 1M+ rows?
Thanks John, that's a great suggestion. Unfortunately it's looking like it will take about 7.5 hours to import 3.12M rows: 1 tables, 3,123,800 records companies: 1% | | ETA: 07:25:34 I'm wondering if there's a more expedient route... in the past I've used the postgres COPY command [1] to do bulk imports of large data sets quickly, but that requires that the server be able to read a file off the server's local filesystem. I don't suppose that's feasible given how the Heroku platform works, but would love to be pleasantly surprised :) Anyone from Heroku able to pipe up and offer any other possible suggestions? Just to restate the problem, I have a single table with about 3.12M records that I'm wanting to transfer from a local DB to my remote Heroku DB without touching the other Heroku app data. It's ok if the table gets blown away on the Heroku side as it has nothing in it (new model I just added).

Re: Best way to DB import 1M+ rows?
Thank you David and Peter for your awesome ideas. Reading back over the postgres COPY command docs [1] it doesn't look like that would ever be a feasible solution given the following stipulation: Files named in a COPY command are read or written directly by the server, not by the client application. Therefore, they must reside on or be accessible to the database server machine, not the client. They must be accessible to and readable or writable by the PostgreSQL user (the user ID the server runs as), not the client. COPY naming a file is only allowed to database superusers, since it allows reading or writing any file that the server has privileges to access. So, it looks like this is something Heroku would have to wrap into an abstracted administrative function down the line, if they ever did it at all, due to the super-user access requirement. Given that, the remaining options consist of a.) restoring a partial backup or b.) doing raw inserts. a.) seems like it would be possible using a dedicated db + heroku pg:ingress + pg_restore -a -t tablename b.) is of course possible via a variety of methods (rake task, REST API, taps, etc) but unfortunately rather slow as there is a lot of overhead in doing single inserts (when compared to writing table structure directly, etc.) I'm thinking I'll give option (a) a try and see how it goes. -Zach [1] http://www.postgresql.org/docs/8.4/interactive/sql-copy.html On Friday, December 10, 2010 at 3:12 PM, David Dollar wrote: Another possible solution would be this: Upload your data in CSV/TSV/whatever form to S3. Write a rake task that does the following: * download from S3 to RAILS_ROOT/tmp * use the psql command line tool (it's on our dyno grid) or one of the ActiveRecord bulk import extensions to read the file and import to your database Then you can run it with heroku rake my_import_task If this is going to be a regular process, you'll likely want to wrap all of this up as something you can run from a worker using DJ or its' ilk.

Best way to DB import 1M+ rows?
I'm wondering if anyone has had experience importing a large amount of data into their heroku database and how they went about doing it. I'm staring down about 3-4M rows of (static) data that I'd like to get into our DB on Heroku. If I had my own database locally I would probably use the COPY command as it is blazing fast. Inserting a row at a time from ruby code or going through an exposed API is looking like it will take multiple days to do (without spending extra money to crank up more dynos and buy a larger DB option) Another option I thought of would be to figure out a way to load the data in a local db then dump only that table and restore it into the heroku db as a partial backup, but I didn't see any facility for that. Has anyone done anything like this or think of a good way for doing it? Thanks, Zach -- You received this message because you are subscribed to the Google Groups Heroku group.

Determining Database Size?
I was looking for a way via the web interface or command-line to determine the size of my database. Could anyone point me in the right direction? I've dug around and searched but not having much luck. For the Heroku folks - a point of feedback - the place that I would expect to see my database size would be in the same place along with my other data in the General Info section.
