Using the sObject Collection Sync Up Target
For the very best performance in large sync up operations, Mobile SDK 10.1 introduced an sObject collection sync up target.
Swift
Objective-C
This target enhances the standard sync up target behavior by using the Salesforce sObject Collections API. This API sends local records to the server in batches of up to 200 records. This target can be up to five times faster than the Batch sync up target, and up to 10 times faster than the standard single record sync up target.
Actual performance can vary depending on specific records, sObjects, and network conditions.
Objective-C
Existing sync up targets in hybrid and React Native apps automatically use the sObject collection sync up target.
This behavior replaces the automatic use of the Batch sync up target. The new sObject collection target is backwards compatible, and should result in improved performance without requiring any changes to your code.
To use a different sync up target implementation such as the legacy SyncUpTarget
class, specify that class in the “androidImpl” or “iOSImpl” setting.
By default, sync up targets defined in sync config files use sObject Collection APIs. For example, the following sync configuration creates an sObject Collection sync up target.
