  • Spring Caching / Data Handling

    Hi All,

    I'm new to Spring.. I'm looking some nicer way to handle data / cache in spring..
    Here is my use case..
    steps #
    1. User uploads the CSV file in (maximum of 5000 records) in page-1
    2. Get some basic parameters in page2
    3. Get some specific parameters in page3
    4. Some more inputs (cont. of page3)
    5. After page 4 user submits for calculation
    6. Application will do some calculation based on csv file uploaded in step1 and inputs got from user in page2, 3, & 4.

    Question :
    1. Application will receive file in step1 / page1 but which is required in page 4 for calculation

    What is your suggestion to hold that file (in cache / session ???) which is received in page1 to keep it live till calculation .. I don't prefer to store in DB since that may slow down the performance also requires additional effort to cleanup ...

    I read about Spring session based bean but not sure how good about performance and cache...

    Can you suggest something for us.
