    Description

      Arrays and structs are converted to json strings before returning them to the clients. This can be tricky because of:

      • handling of special characters, e.g. quotes
      • possibly huge memory consumption, especially for large arrays

      We should investigate whether we can use a library (currently RapidJSON) or we'll need to implement it in Impala.
