Heroku Postgres
- joevandyk 15y agoAlthough they only let you create one database per plan, you can use schemas to emulate multiple databases. http://www.postgresql.org/docs/9.0/static/ddl-schemas.html http://www.postgresql.org/docs/9.0/static/ddl-schemas.html
- pvh 15y agoJust to clarify: You're almost right. You can, in fact, create multiple databases of any plan you please, but yes, within each of those databases you can use schemas to implement something akin to multiple databases without resource isolation, but with the ability to share data.
- jvehent 15y ago"Forget daily backups, Continuous Protection redundantly archives data to high-durability storage as it is written, ensuring that it is safe no matter what." I'm sorry, but daily backups are not only for high availability, but also for point in time recovery. What if $dev drops the user table by mistake ? Do they provide backup for that ?
- joevandyk 15y agoYou can make snapshots of the data.
- olefoo 15y agoYou can set up Point In Time Recovery (PITR), and replay recovery logs. It's not clear from Heroku's pages whether their solution is set up that way.
- jpitz 15y agoIt sounds like their solution is set up that way. From https://postgres.heroku.com/#protect https://postgres.heroku.com/#protect : "Every change to your data is written to write-ahead logs, which are shipped to multi-datacenter, high-durability storage. In the unlikely event of unrecoverable hardware failure, these logs can be automatically 'replayed' to recover the database to within seconds of its last known state."
- pvh 15y agoWe have found that large production databases do not appreciate having frequent full SQL dumps taken from them. We offer an automatic daily snapshot option because we believe that for a production database it's really not wise to take dumps more frequently than that, though there's nothing stopping you from rolling your own.
- olefoo 15y agoJust a little usability nit, is the pricing per month, per year, lifetime? It's not clear from the pricing page, and I'm assuming it's per month, in which case it's reasonable, especially given the value added services being offered, especially the ability to fork the database and the automated creation of read slaves. It looks like a solid offering. It's probably not right for companies that are subject to HIPAA or PCI compliance requirements, and there's no information on the use of compiled extensions in the db which may limit it's utility if you're wanting to use PostGIS or other specialist datatypes.
- wtn 15y agoBasic plan is $200/month.
- msmith 15y agoI'm sure it's monthly. The price tiers are the same as the full Heroku platform (http://heroku.com/pricing http://heroku.com/pricing), which is billed monthly.
- pvh 15y agoI would say that at this point you're right, we're probably not right yet for companies subject to HIPAA or PCI regulation. The advanced Postgres datatypes are pretty much my favorite thing in the world. We use HStore internally all over the place, as well as some more exciting projects that we haven't said too much about yet. As I mentioned elsewhere in the thread, if you're interested in trying out some of those extensions, contact me directly.
- olefoo 15y agoI'm a real fan of PostGIS and like ltree and hstore a lot. Heroku isn't quite right for my needs at this time, but I would definitely consider it if I had a use case that needed an extremely fast public facing postgres installation. I am curious as to whether you do pro-rated pricing?

- francoisdevlin 15y agoI think the Fugu plan is a typo, if you're reading this Heroku guys...
- wccrawford 15y ago'has' a typo, you mean.
- sgrove 15y agoThis is really exciting - the team behind this really cares about developers and their experience. They see a way things could be better, and regardless of technical difficulty, say, "why not?" Forking a db? Brilliant. Offload expensive task to passive followers? Obvious (in hindsight). Instant, brain-dead db provisioning? Of course. Personally, the only terrifying thing about this is that when Heroku releases something, it's been in the works for a good long while, and they usually have a stream of incredible releases waiting right behind it. The mind boggles at what they're going to be doing next. But we'll be first in line for it :)
- jinushaun 15y agoWhen I read "forking" and "following" on there, it was a revelations: of course, that's so obvious! Those terms are much friendlier than "replication" or "master-slave". It describes the desired result, instead of the underlying technology.
- pvh 15y agoIf you had any idea how long it took to get that language right...
- andypants 15y agoThis is really awesome, just a few downsides (for me): I don't use postgres - I hope heroku expands this kind of service to more databases (although I don't think it's likely in the near future). The smallest database is also pretty expensive. I wouldn't mind a cheaper plan for less resources. Only being able to create one database of each size is just weird, especially if forking or following. Can anybody confirm that this is a limitation? (I only read about this from one of the other comments here)
- bad_user 15y agoIn case you're using Mysql, give Postgres a try -- it's really awesome. I do agree about them being expensive. Their services in general are too expensive for me -- personally I prefer to manage my own EC2 instances. But they do provide value worth paying for depending on your needs.
- khoffrath 15y agoFor a similar service using MySQL you can try http://xeround.com/ http://xeround.com/. (Disclaimer: I haven't tried it myself and have no association with them)
- pvh 15y agoWe are unlikely to offer MySQL at any point in the near future. We feel that across the board, Postgres has the best data robustness guarantees, the most powerful query optimizer, the strongest replication solutions, the most useful datatypes, and the greatest community driving, developing and supporting it. We hear you on the cheaper plan; watch this space. Last, there is no restriction on creating only one database of each size.
- latortuga 15y agoHonestly when you list the merits of Postgres like that you sound like a used car salesman. "Of course you think you want that but really you want all of this." We all get that Postgres is great. Saying "no we won't implement a feature you, our customer, wants" like this just rubs me the wrong way. Is there some technical reason that you can't offer both?
- swilliams 15y agoIt would seem that their acquisition by SalesForce hasn't slowed them down at all, in fact I'd go as far to say that they've been even more productive since that happened. I'm curious about how that whole process has gone; has SalesForce provided more support/funding/resources? Or just removed distractions and allowed them to focus on their product? Nice job Heroku.
- pvh 15y agoSuffice it to say, any rumours of our demise were greatly exaggerated. So much more to come and yes, we are hiring, including for our Postgres team. (Resumes/github accounts/etc to jobs(at)heroku.com.)
- drewcrawford 15y agoThis is ridiculous, but I would love a REST interface to a SQL server. I do a lot of AppEngine work and although I love the datastore and write super-optimal queries, I would really love the ability to pull a SQL datasource in every once in awhile.
- pvh 15y agoCheck out the extremely cool HTSQL from Clark Evans!
- volkadav 15y agoNot exactly RESTful but you might find some utility in this, developed at and open-sourced by the NYT: http://code.nytimes.com/projects/dbslayer http://code.nytimes.com/projects/dbslayer (edit to add: this is mysql-only, unfortunately :) I forgot about that part when I remembered it off-hand.)
- boundlessdreamz 15y agoIf there is anyone from heroku reading, please pay some money to http://www.sequelpro.com/ http://www.sequelpro.com/ developers to develop postgresql compatibility. All GUIs available on OS X for postgres are horrible
- jinushaun 15y agoI love using Sequel Pro for MySQL, but also wish it had support for SQLite and PostgreSQL. It's a great app and better than all the other OSX clients that I can find on the internet, including the non-free ones. It's open source, so nothing's stopping anyone from adding support for other SQL servers.
- jasonjei 15y agoIs Navicat OK? I've been using it for a while simply because it was one binary that did SQLite, MySQL, Oracle, MS-SQL, and PgSQL.
- dwillis 15y agoI've used Navicat Premium with Postgres and have had no issues. Pricey, but it works.
- dewiz 15y agohave you considered Navicat ? there is also a free version and it runs on windows, osx, linux
- jabkobob 15y agoI have contributed a little bit to Sequel Pro, and I'm a bit familiar with the codebase. Adding support for PostgreSQL is not trivial, a lot of MySQL is hardcoded into the user interface. There have always been many requests for PostgreSQL compatibility, but it would require A LOT of refactoring. (Disclaimer: I haven't been involved much with SP for almost a year now, so possibly there has been progress in that time)

- firemanx 15y agoDo they still limit the usage of user defined functions and contrib modules, or did that open up? I would love to use Heroku for some lightweight data warehousing that I've got going, but it's still pretty dependent on functions/sprocs for performance reasons. I looked for any more documentation about that, but the only official word I have from them in the past is the support ticket I filed last year stating that they don't support "additions" like user defined functions or the various contrib modules.
- pvh 15y agoOur production service has always supported UDFs, though the free sandbox service does not. Unfortunately, Postgres makes it difficult to install extension modules without superuser. That said, we've wanted to support contrib modules for ages. Lately, encouraged by the work Dimitri Fontaine has been doing on extensions, we have a pilot project going which includes support for hstore, pgcrypto, pg_trgm, and of course, postgis. Feel free to contact me at pvh(at)heroku.com if you're interested in taking it for a spin.
- samstokes 15y agoWe're running user-defined functions on Heroku right now (using a functional index on a custom hash function to get fast space-efficient queries on a string column of a large table).
- hopeless 15y agoI just realised that Heroku have a problem: when I looked at the page, and looked at the subdomain URL, I couldn't tell if this was a real offering or a fake app put up by someone else.
- pvh 15y agoYes, it's the real deal, just like blog.heroku.com and all our other services. In order to reduce this ambiguity we are gradually moving towards placing user apps on a different domain; because we approach these kinds of issues very gradually this will probably take quite some time to fully complete, but as of today all new Cedar stack applications are hosted on herokuapp.com.
- hopeless 15y agoAh, good to know. I haven't got around to creating a Cedar-based app yet
- pbh 15y agoAny chance of PL/python or similar? I guess I'm probably one of like three users of PL/python, especially since it's untrusted. Worth a check, though!
- pvh 15y agoNo plans to support untrusted languages as yet. Too many foot-guns built into that. You couldn't even believe some of the evil, insane things that we've done with that. Trusted languages are far more likely. This one looks really, really cool: http://code.google.com/p/plv8js/wiki/PLV8 http://code.google.com/p/plv8js/wiki/PLV8
- rbranson 15y agoIs this still using the EBS RAID that you guys mentioned in a blog post a while ago? If so, how do you avoid any slow I/O requests (which plague EBS) stalling all I/O to the volume?
- pvh 15y agoActually, Postgres WAL support helps mitigate this reasonably well, and a well tuned application has something like a cache hit rate of >99% during normal operation. That said, yes, EBS can have unstable performance. We monitor for several kinds of related problems and in the most dire of straights can perform a hardware migration to a quieter node which generally clears issues up.
- Fluxx 15y agoThis is really awesome! A couple questions though: * What do I do if I need to tune/configure Postgres for my workload. * How is the performance of transferring all of the queries and responses across the internet? Keep in mind I've never used postgres before so these may be moot points.
- pvh 15y agoWe've done a lot of tuning focused on web applications already, our experience is that mostly people with problems just need to add an index. Performance depends on where you are querying from. We've found that if you are inside EC2 network overhead is typically <1ms.
- laran 15y agoThis blew my mind. Amazing stuff. Heroku is absolutely my favorite platform.
- mberning 15y agoThis is cool, seems to have a pretty fair price structure. I still don't understand their shared database pricing. 5mb for free, then $15 for 20gb. I need like 100 megs for 5 bucks.
- njharman 15y agoneed GIS And confused by "one database only". Does that mean CREATE DATABASE databases? If so why?
- abhishektwr 15y agoYa me too, no mention of PostGIS.
- pvh 15y agoPostGIS is currently in a pilot phase. If you're serious, please contact me as described elsewhere on this thread.
- kashifr 15y agoHi co-founder of SpacialDB here. Cloud hosted PostGIS is already available as a Heroku plugin, stand-alone and an easy to use API. Check out http://devcenter.spacialdb.com/ http://devcenter.spacialdb.com/ for documentation and you can sign up via the Heroku addons page or http://beta.spacialdb.com/ http://beta.spacialdb.com/
