Data insertion into MV table happens at the same time you insert data into source table.
If insertion into source table returns `ok`, new data is inserted in both source and MV table. This insert is not transnational, however. It means, there could be a moment when `select` can get not consistent data while readi... | 2021-03-29T09:22:47 | 2021-03-29T09:22:47 | {

The issue can be caused by many reasons.
Most likely it should be investigated with the help of kdc logs, client is usually not informed of what exactly went wrong.
