Fast sync

When setting up Avni freshly on an android device the first-time sync can take a lot of time, especially if you have a lot of transactional data for the catchment. To make this process faster Avni provides an option to set up fast sync for a catchment.

The performance of syncing data from the server to the local mobile database is dependent on the volume of data - hence cannot be improved significantly. Hence fast sync depends on using the already synced mobile database file as the starting database for other users. This significantly improves the sync duration to less than 5 minutes in most cases.

There are few things to note before we start setting up fast sync.

Fast sync is set up for a catchment, so if there is a new user in a catchment called "a" then any existing user of the catchment "a" should set up the fast sync from their device.
Fast sync does not update automatically, which means if the user has set up fast sync one month earlier, then all the data filled after that will get downloaded by the regular sync. So it is recommended to update the fast sync whenever any user is freshly setting up the Avni on their device.
Fast sync is triggered only when the user is syncing for the first time. So if the user has not logged in for a long time, then it is recommended to delete all the app data and log in again to use the fast sync.

Setting up fast sync

.Setting up fast sync is very easy and it requires an active internet connection. Existing users can go to "More -> Setup fast sync" and then click "Yes". This will take a while depending on the data in the device. This uploads the database file from the user's device to Avni storage as fast sync file for this catchment.

Once it is done, the new user from the same catchment will get an option to use the fast sync when he logs in for the first time.
