I store many sub records as Map in the same top record, now I need remove some sub records according to passing keys, I plan to use UDF to implement it. When I invoked from Java, the log shows the length is 0. Why? and how to correct this? Thanks!
In Java =>
val ids = Array(1,2,3)
Value.get(ids)
In Lua UDF =>
function remove_keys(rec, binName, rmkeys)
info("Value(%s) valType(%s)", tostring(rec), type(rec));
info("Value(%s) valType(%s)", tostring(binName), type(binName));
info("Value(%s) valType(%s)", tostring(rmkeys), type(rmkeys));
info("BinName(%s)", binName)
info("len(%s)", tostring(#rmkeys))
...
end
