At the moment, we are in the final stage of releasing our DAM connector plugin for Drive, and we are doing some performance testing. While debugging I noticed some strange behavior. For example, when you start Drive, the HandlerFactorty is instantiated for about 7 times. The same strange behavior comes back in the OpenHandler. When I open a file (for example an InDesign file) from Bridge, the handler is called for about 5 times per file. And after every call the closehandler is also called. This makes 10 calls in total for just opening a file.
Some other thing I noticed, is when you are browsing to a folder with for example 14 assets inside it, the GetAssetsHandler is called 14 times. I should expect that this handler is just called 1 time, and the 14 assest are injected through the GetAssetsRequest class. The same behavoir comes back with other handlers (MoveHandler, CopyHandler). There is also an inconsistency in this behavior (the DeleteHandler does get all the files at once through the DeleteRequest class).
I also discoverd a difference between a move inside bridge and a move in explorer. When I move an item in bridge, the CopyHandler is called and the file is copied instead of moved. When I move an asset in explorer, the movehandler is called as expected.
These issues are very concerning for me, because I have the feeling that they are effecting the performance of Bridge and Drive. Can you straighten out some of these issues? Maybe I'm missing something, or doing something wrong here?
1. I'm using Adobe Drive 3.0.070. In the mean while we've tested this on several developers machines (windows, not mac) and on the most of them it is instantiated more then 2 times
2. Problem is, that we are calling a webservice for retriving our Assets, and it would be way more performant that we can make 1 call with 14 files instead of 14 calls with 1 file. Is there an alternitave available for this handler so that we can make 1 call to our service?
3. Indeed, I was moving items between root classifications. When I move between folders underneath the root, it does actually move.
4. We'll take a look at caching the assets in our connector.
Thx for the advice.
Currently I'me investigating the Caching posibilities, more specific the cache state checking. I have implemented a Custom (dummy) statechecker, which is registered in the ConnectHandler (as explained in the Advanced topics in the Programmers guide). This checker always returns false.
But when I debug my plugin, the isAssetStale is never triggered. Could you tell me when this function is normally triggered?
When the file on the server is not modified, you should not change the ETags. For example, you check out a file, assuming that the ETags value is 123456, then you edit that file, the ETags should still be 123456. After you check in that file, the ETags should be updated with new value which is greater than 123456.
