amazon-simpledb

问题 I've been browsing for a week on how to use AWS. I've always been using cpanel (I'm new to web) but someone recommended AWS to me. From the info I pieced together from various websites, I think I'm supposed to do the following?: 1) copy my website files to S3 2) set up an instance in EC2 3) set up volume in EBS and attach to instance 4) set up elastic IP and attach to instance. 5) ?? The questions are, 1) is this correct? 2) Where and how do I create mySQL database? Do I use SimpleDB, Where

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 months ago . When would you use a bigtabe/simpledb database vs a Relational database? 回答1: Relational databases give you a lot more layout and query flexibility, and are easier to use, but you also end up with more pain if you later need to partition your data if it won't fit on a single

问题 I am using simpleDB GORM with my grails application, though simpledb is great its a huge drag while in development mode, every click takes few seconds resulting in not so rapid development. From what I understand simpleDB comes into action only if domain class has following two lines in code String id static mapWith = "simpledb" So, my question is, is it possible to remove/hide these two declaration on the fly from domain classes depending on some kind of flag? Same question asked differently

问题 I'm trying to figure out how to store a database consisting of metadata in Amazon SimpleDB, with the actual content the metadata refers to (videos) in S3. As I understand it, I should place a pointer in SimpleDB that refers to the videos in S3. What is this pointer, exactly? Is it the URL of the video located in S3? Also, are there any code samples that would pertain to this? Thanks! 回答1: You're right, just enter the url on simpleDB and you're done. What you're trying to do is pointed as an

问题 I'd like to use SimpleDB for a mobile app. I have user accounts so I would have a 'TVM' which would authenticate the user and return a time limited token which allowing the mobile app to directly make SimpleDB calls. I believe however there is no way to do this securely assuming the app needs to be able to write and select from the database. A malicious user could simply retrieve the token and write their own SimpleDB calls which could write anything to the DB. Is it true that the only way to

问题 I'm looking for a common data access framework that will provide portability across various nosql databases like SimpleDB, Azure Tables, Cassandra, CouchDB, MongoDb, etc. I'm building an app and would like my customers to be able to use which ever nosql store they want. In a more relational scenario, I'd use Linq over nHibernate or Entity Framework, but I haven't found an equivalent framework for nosql databases. All I've found is database specific API's even though there seem to be

问题 i have tried offset in simpledb but its not working as it working in mysql , and i want to do paging for my database api in php so that i send the pagenumber and pagelength to the query and it will return the data of that page only. How this i can do in simpledb. select * from second where time_stamp is not null and gibid = '54' and gibview = 'O' order by time_stamp asc limit $pagelength as offset is not working so i can't add offset in query. I have google and find there is next token is

问题 I'm using Amazon's tools to build a web app. I'm very happy with them, but I have a security concern. Right now, I'm using multiple EC2 instances, S3, SimpleDB and SQS. In order to authenticate requests to the different services, you include your Access Identifiers (login required). For example, to upload a file to S3 from an EC2 instance, your EC2 instance needs to have your Access Key ID and your Secret Access Key . That basically means your username and password need to be in your

问题 Sorry if this question is somewhat subjective. I am new to 'could store', 'distributed store' or some concepts like this. I really wonder what do they have in common and want to get an overview on all of them. What do I need to prepare if I want to write a product similar to this? 回答1: The NoSQL Database site summarizes the concept like this: Next Generation Databases mostly address some of the points: being non-relational, distributed, open-source and horizontal scalable.
