OdataLink Models have archive types


These include Live, Developer and Static
To speed up the time it takes to refresh data, OdataLink's models include an archive.  You can control how the archive works by changing the '''Archive Type''' option.
 
The possible values are:
* Live
* Live (no archive)
* Developer
* Static


Those in addition to Live exist to improve the refresh rate in scenarios where speed is more important than retrieving latest live data from the source


=== Live ===
=== Live ===
Optimises the model for end user use.


At all times the latest data is returned.  
When the '''Archive Type''' is set to '''Live''', OdataLink will serve data directly from your [[Data Files!data file]].
 
This is the preferred option once you have finished building your reports and development is complete.
 
Some endpoints which cannot be edited, such as [[Xero Accounting Endpoint: JournalsAccrual]] and [[Xero Accounting Endpoint: JournalsCash]] will get cached in an encrypted archive to speed up refreshes. This only applies to endpoints whose data never changes.
 
 
=== Live (no archive) ===
 
When the '''Archive Type''' is set to '''Live (no archive)''', OdataLink will serve data directly from your [[Data Files!data file]].


Its the slowest for returning data
This is option is only recommend for those that need maximum security. It does come at the cost that some endpoints will be particularly slow.


To be used once development is completed


=== Developer ===
=== Developer ===
Optimises the model for development.
 
When the '''Archive Type''' is set to '''Developer''', OdataLink will be optimised for developing reports. In this mode, Live data will only be served once every 8 hours. If a refresh takes place within 8 hours of the last refresh, it will instead served cached data stored in an encrypted archive.
   
   
Cached data is returned where the last retrieval was less than 8 hours ago
The benefit is that it makes refreshes faster but at the cost of not always retrieving the latest data.


The benefit of this Archive type is that it makes refreshes faster but the downside is your not always retrieving the latest data.  
This is the default when creating a model.  


This is the default when creating a model.  
This is the preferred option when building reports. It should be changed to '''Live''' or '''Live (no archive)''' once development is complete.


Once development is completed switch it back to '''Live'''


=== Static ===
=== Static ===
Optimises the model for historica data that never changes.


that data to pull blocks of records that will never change.  
When the '''Archive Type''' is set to '''Static''', OdataLink will only query data from your [[Data Files|data file]] once.
 
This option is mostly used for data that never changes such as historical data.


The model only returns the latest data once for the defined parameters and then caches it and only ever returns that cached data going forward.


Use this option if you wish to report on historical data from previous financial years and append with live data for the current year.
