Last Update: November 17, I do not buy all the hype around SimpleDB and based on the following limitations can not see a reason why it should be used I understand that now you can build almost anything with almost any technology, but this is not the reason to select one.

If this is not enough, then you also have to forget about the basic things like group by , sum average , distinct as well as data manipulation. In whole the query language is pretty rudimentary and reminds a small subset of what SQL can do. And at last - do not forget about vendor locking. If in a couple of years Azure or something else that would appear will provide a cloud hosting 5 times cheaper than AWS, it would be really hard to switch. The point of SimpleDB.. Note, it does not have to be for S3 specifically.

SimpleDB is a great solution for providing a simple fast index for just about anything. I find DynamoDB overkill and unnecessarily over complicated in terms of provisioning for your needed throughput and how that relates to cost, and have heard horror stories related to that. With SimpleDB the performance is consistently good and the costs are predictable. They can't phase out SimpleDB because there are too many existing customers in-the-know that rely on it.

AWS relies on it themselves as well. If it truly was supplanted by DynamoDB as they claim then everyone would have moved over to Dynamo and this would not be a discussion.

Thanks, I didn't appreciate the importance of linking with s3. Still I don't see any use case personally. For example in case of comments, storing comment body outside would make it impossible to search through them, which was one of the things I wanted to do. In other words, for large fields the built-in SimpleDb indexing wouldn't be useful anyway. SimpleDb was ditched by Amazon in part because implementing anything with it was never, ever simple.

SimpleDB was not 'ditched' or 'deprecated'; I work for AWS, though not in this service, and it is not something we do. It is feature complete and most people saying "implementing anything with it was never, ever simple" probably would say the same about DynamoDB which is scads more difficult to get right — LimpingNinja. Bill Karwin Bill Karwin k 81 81 gold badges silver badges bronze badges. Some of the features on my roadmap are related to the issues you've mentioned: Transparent partitioning of data Pseudo transactionality Transparent spanning of attributes to surpass the byte limit SimpleDB is still under active development and will certainly end up with many features it doesn't have today some added to the core system and some in the code libraries.

So the limitations I have seen: can be run only on amazon AWS, you should also pay for a whole bunch of staff maximum size of domain table is 10 GB attribute value length size of field is bytes maximum items in select response - maximum response size for Select the maximum amount of data that can return you - 1Mb, actually you can check all the limitations here has drivers only for a few languages java, php, python, ruby,.

If 5 seconds passed and the query has not finished, you end up with a partial number and a token which allows you to continue query. Application logic is responsible for collecting all this data an summing up. So now you have to do a shamanic dance with padding both do not have transactions and joins no compound, geostatic, multiple column indices, no foreign keys If this is not enough, then you also have to forget about the basic things like group by , sum average , distinct as well as data manipulation.
