Can you please tell me - the table “data0” in the compressed depositories - what is it used for?
The “data0” table contains start values (values of objects older than the start time of the depository). They are there to optimize the reading of the values. If some value (e.g. Boolean) does not change for several months, so that it is not necessary to read several (monthly) depositories before it is found.
