[FEA] Json reader not inferring list types #7086

Closed galipremsagar closed 2 years ago

galipremsagar commented 3 years ago

Describe the bug When a list column is being written to a json file, while retrieving it via cudf JSON reader the data is being truncated and the list column is being inferred as a string column.

Steps/Code to reproduce bug

>>> import cudf
>>> df = cudf.DataFrame({'a':[1, 2, 3], 'b':cudf.Series([[1, 2, 3], [2], [3]])})
>>> df
   a          b
0  1  [1, 2, 3]
1  2        [2]
2  3        [3]
>>> df.to_json('sample.json', lines=True, orient='records')
>>> cudf.read_json('sample.json', engine='cudf', lines=True, orient='records')
   a    b
0  1   [1
1  2  [2]
2  3  [3]
>>> import pandas as pd
>>> pd.read_json('sample.json', lines=True, orient='records')
   a          b
0  1  [1, 2, 3]
1  2        [2]
2  3        [3]

Expected behavior

>>> cudf.read_json('sample.json', lines=True, orient='records')
   a          b
0  1  [1, 2, 3]
1  2        [2]
2  3        [3]
