Providing row level access in druid

Hi,
I was exploring the ways to provide role level and row level access to the druid table , I came across this extension which provide the role level access , but I am looking something for the row level access too.By row level I mean suppose we have a data of various organization stored in the db and each organization is identified by a unique id(context_id), so any user who request access to this data will only be allowed if he/she has permission to access the data from the requested context. Can this be achieved in druid ?
