Subject [jira] [Created] (APEXMALHAR-2474) FSLoader only returns value at the beginning

-------------------------------------------

             Summary: FSLoader only returns value at the beginning
                 Key: APEXMALHAR-2474
                 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2474
             Project: Apache Apex Malhar
          Issue Type: Sub-task
            Reporter: Pramod Immaneni


FSLoader implements Backup store for db CacheManager. In the initial load, it reads all the
lines of the file, line by line, and returns a Map of key-value pairs with a key-value pair
for every line. It returns data only on the initial load and thereafter it returns null for
any key lookup. Also, there is no need to load all the data in the file and return it if the
primary cache cannot hold all the entries. These issues need to be addressed and it also helps
if the CacheManager supplies meta-information such as how much information should be loaded
and returned in the initial load.
