data-synchronization

Anybody has any ideas or references on how to implement a data persistence layer that uses both a localStorage and a REST remote storage: The data of a certain client is stored with localStorage (using an ember-data indexedDB adapter). The locally stored data is synced with the remote server (using ember-data RESTadapter). The server gathers all data from clients. Using mathematical sets notation: Server = Client1 ∪ Client2 ∪ ... ∪ ClientN where, in general, any record may not be unique to a certain client: ClientX ∩ ClientY ≠ 0, ∀ X,Y ∈ [1,N] Here are some scenarios: A client creates a record

I'm looking into building an application which works just as well offline as it does online. Since the application cannot communicate with the server while in offline, there is some level of synchronization which needs to take place. What are some good tools to read about and start thinking about when planning offline operations with synchronization for your iPhone? What tools would I have to create on my own, versus tools that apple already provides to help with this particular issue? there are plenty of application on the app store which rely on both online as well as offline data what you

In my previous question on this portal, I had asked about some insight about syncing data between SQL Server and key-value based data repositories. In lieu of the same problem (one way real-time synchronization from SQL to HBase or any other database), I need to take care of some performance and latency considerations and did not find a very foolproof way of doing it. We have multiple SQL 2008 data shards where data is updated from various sources and processed by many processes at the same time (and UI reads from the same shards). The goal is to get all updates in selected tables at any point

I am looking for a way to synchronize my data from MySQL to MongoDB. I do not want just to replicate my data, I want them to be permanently synchronized. Does anyone know if Tungsten Replicator would do the job ? I can see that it replicates data but what about replicating data automatically when changes are made in MySQL database ? If not possible would you suggest any other solution to do this ? Yes Tungsten Replicator provide real time synchronization between MySQL and Mongodb however to get your old data replicated you can use other tools like mongify to get old data. Best of Luck! Yeah

does anyone know if and how you can sync CoreData apps with iCloud? If I understand the Apple iCould instructions right you can not sync CoreData, can you? Given that you tagged this with Cocoa, I suggest that you watch the video for WWDC 2011 Session 315 - "What's New in Core Data on Mac OS X". For iOS, check out Session 303 - "What's New in Core Data on iOS". These will answer all of your questions regarding Core Data and iCloud. Since this is still under NDA, that's the most I can tell you. Here's an article with sample code: http://goddess-gate.com/dc2/index.php/post/452 . I am going to

I'm currently in the process of writing an offline webapp using all the html5 goodies for offline support. However I'm starting now to think about writing the sync module that will ensure that any offline data gets sent to the server and server data back to the client. Now I'm sure this has been done before, I mean its a pretty classic design issue that affects mobile devices and a plethora of other things. So I'm wondering can anyone point me to some good design resources for this kind of thing? Now I really do not need to be too sophisticated with this, I mean I'm not handling multiple users

I am using pysftp library's get_r function ( https://pysftp.readthedocs.io/en/release_0.2.9/pysftp.html#pysftp.Connection.get_r ) to get a local copy of a directory structure from sftp server. Is that the correct approach for a situation when the contents of the remote directory have changed and I would like to get only the files that changed since the last time the script was run? The script should be able to sync the remote directory recursively and mirror the state of the remote directory - f.e. with a parameter controlling if the local outdated files (those that are no longer present on
