@willforevercn Yes, MapType is supported for string as key only. Above code
works with following snippet -
```def get_tags():
count = random.randint(0, 5)
tags = {}
for i in range(count):
key = tag_ids_all[random.randint(0, len(tag_ids_all) - 1)]
value = 1.0
tags[str(key)] = value
return tags
tags_udf = udf(get_tags, MapType(StringType(), FloatType()))```
