I try to scan all values from Ignite cache. I manage to create generator with cache.scan() method but when I want to get next value from generator it freezes.
from pyignite import Client
client = Client()
client.connect('127.0.0.1', 10800)
cache = client.get_cache('CACHE_NAME')
all_results_gen = cache.scan()
result = next(all_results_gen) # makes interpreter freeze
EDIT:
It may be related that this cache is also used by Java app.
EDIT2: I think it might be something about java types conversion to python. Maybe with sql queries it will be easier to get this values.

How many entries in this cache? Any errors displayed on server node?

There should be 29 records so that's not about quantity also there is no error thrown at ignite server

Java app creates cache with table for example Measurement. While i try to select with pyginite and sql query like client.sql("SELECT * FROM Measurement") it shows that there is no table with this name.
