Hi Marcos,

CUSTOM would mean that the DBExpress driver you are using supports it.
That is, the value you set for the CustomValue in the TransactionDescriptor
should be used by the driver.

Do you know if it does?

As for reading the docs, I believe that SNAPSHOT pretty much is the same as
REPEATABLEREAD - can someone comment on this?
