    [CARBONDATA-1909] Load is failing during insert into operation when load is concurrently done to source table

    Load is failing during insert into operation when load is concurrently done to source table
    
    Scenario:
    Client1:
    1. Create source table
    2. load big data
    
    Client2:
    1. create table t1
    2. insert into t1 select * from  source table   - load fails
    
    Data Load:
    Step1 : Dictionary Generarion
    Step2: Loading data
    
    Assume 100 records is read from source table using select statement, but when execution reaches step2, 50 more records has been added to source table. So when select happens on source table during data loading , it gets new record for which dictionary is not generated. So there is inconsistency.
    
    Solution : 
    To solve this issue we persisted dataframe, so that select will not get fired for second time. But this has some performance impact. So we are providing configuration to enable persist, if user wants to perform this kind of scenario he can enable this configuration at cost of performance.
