Hello!
As you know, the generic MIDAS frontend has a class driver, device driver, bus driver
structure. Assuming a slow device frontend, its class driver should have a routine of type

Dear Konstantin,
thank you very much for the explanation. I already have an idea of how to solve my problem by bypassing the class driver altogether or by slightly modifying
the mfe.cxx frontend.

Dear Stefan,
thank you very much for the clarification. I knew about the DF_XXX flags and I am making good use of them in all my frontends. Anyway, what I really needed
was to change the readout rate depending on the run status (in particular DF_RUNNING or DF_TRANSITION).

Dear Stefan,
Thank you for the advice. I will try to modify the driver as you say. As for the dynamical change of readout rate, basically you are telling me that is
not achievable without dirty hacks like mine and it is better to find a way to avoid it.

All this is very good news. I really wish this were available some months ago: it would have helped me immensely. The old C API was clunky at best.
I really like the idea and looking forward to using it (even if at the moment I do not have the need to) ... |

Eventually, I have settled for the SQLite format.
I could convert the MIDAS history files .hst to SQLite
database .sqlite3 using the utility mh2sql.

Sometimes when I mess around with the history plots I get the following error:

It appears that the issue is trigger by a nonexisting Event and Variable as shown
in the attached picture. This issue can arise when restoring the ODB from a
previous version or importing ODB values from other MIDAS instances.
