|ISTOTV-335||Amend ToTV File Download generation process to deal with an increase in number of files published by FIRDS and FITRS|
As a reminder, ToTV File Download data for the day is made available once the DSB has completed processing of FIRDS/FITRS data for the day (see here for information about the DSB ToTV service).
On days when a large number of FIRDS/FITRS files are published, the generation of DSB ToTV Files for Download may complete on the next day and ToTV files timestamped as T are therefore made available on T+1. There is currently an edge case where if data published on T completes processing on T+1, then T+1 data is not made available on T+1, and is included in T+2 ToTV File Download generation instead. The DSB change will allow for T+1 ToTV files to be made available on the same day (T+1) if previous day ToTV files generation ( files timestamped as T) overruns.
- Users who are consuming DSB ToTV Files should expect and code for the possibility that ToTV files dated T will occasionally be made available on T+1 as part of the normal process due to an increased number of FIRDS/FITRS files. Specifically, this scenario is more like to occur on a weekly basis when the Full FIRDS/FITRS files are made available.
