Ceramic cap exposed to a reasonably high constant (not AC) voltage should exhibit practically zero current. The insulation resistance is typically in hundreds to thousands MOhms.
The datasheet will specify that for every type. Anything below that is leakage. An egregious leakage basically turns a cap into a resistor, which you do not want.
