Snapshot Processing

[david_cheong]

1 may you please specify which subscription mode are you referring to?

2 this is correct assuming that after the DataProvider sent the 10th record a call to endOfSnapshot (or smartEndOfSnapshot in case of SmartDataProvider) is issued.

3 there is nothing ready for that; you may use a MERGE item that pushes the number of records in your command table at any given moment.

4 a snapshot is stored per each subscribed item; you can track the number of subscribed items in your DataProvider using subscribe and unsubscribe methods.
You can use your MeadataProvider to track new subscriptions for each single client and track them; take a look to wantsTablesNotification notifyNewTables and notifyTablesClose

I check on my LS snapshot, it only send the last action to my javascript client end which make the data inconsistency. I'm using the Command mode for my application, may i know why this happen?

My issue is i set the unique id for each item and the id is place in the Key parameter when publish the data, after few action done on the same data and refresh the browser to re-subscript the snapshot, i found that LS only send the last action for each unique key.

Can anyone help on this.

Hi David,

I suppose the question is the same of this post.
