Thanks Holly thank you for your response.
1. Change tracking is enabled. I have a second storage account, and I have pointed the reqtrans table to sync there (as well), this has continued to work since I did this on Monday following the failure of the original reqtrans sync.
2. There is no issue with storage account; there are other tables syncing there too without issue. Additionally, when this issue occurred the previous week, I simply unlinked and relinked the table and once it had completed its initial load, syncing commenced as expected.
3. There is an error reported in the logs! Rather helpfully it states "Spark jobs are failing due to internal error, please contact support"
4. I am not sure how to do this. All I have is the data storage, for the initial delta csvs, and the final parquet folder. I can also review the overall batch job. As indicated, I can see that the delta csv;s continue to load, it is the resulting parquet that is not getting updated. The batch jobs have reported no error.
5. This is very much a nuclear option! There are may tables being synced to this location, for which they serve many operational reports. Reconfiguring the synapse link in its entirety would mean these reports would not be available to the business for several days, which is not acceptable (from the business perspective).
I had previously reviewed the MS docs you refer to, they did not provide any help.
Thanks anyway, I very much appreciate your input.
