Android Question Binary diff / Binary patch

[GiulioVale]

Any suggestion for a binary diff? Think a two sqllite db to patch...

 

[Erel]

This is not the correct way to synchronize two databases.

 

[GiulioVale]

Hi Erel I know there is more simple way with a sql diff, but I want explore the idea around a binary diff.

 

[Erel]

How will it help you to know the binary diff? You will not be able to do anything with this information.

 

[GiulioVale]

Think something like http://php.net/manual/en/function.xdiff-file-diff-binary.php

 

[Erel]

I see. You don't want to synchronize two databases, you want to only apply the changes from one database to another. How large are your databases?

 

[GiulioVale]

Around 400Mb

 

[Erel]

I think that it will be simpler to make a query for all the updated results and then add them to the second database. Working with 400mb files on the device can be a slow task.
