Issue with pagination using paging state

2023-09-08 Thread Ritesh Kumar
Hello Team,I am trying to achieve pagination in Cassandra using paging state mechanism.I am trying to paginate through records with LIMIT set to 250 and fetch size set to 50. I get the paging state for the next set of 50 records up until the 250 records are retrieved but how can I paginate further 250 records. If I leave out the LIMIT and simply use the fetch size, I am able to paginate through all the records. I want to understand if leaving out LIMIT causes negative performance impact.Doesn’t  fetch size and limit have similar functionalities? Please help.Regards,Ritesh Kumar  Sent from Mail for Windows
