I have a program which collect data and save it in binary file, It can build a index file IDX.txt with 5 columns ( UID,SecID,Date,Time,address), address is a pointer to data. That program's work flow as below /1. load index as a HoA/ /2. waitting for task/ when get a task, it will do /A. search index HoA to find a new entry and new UID / /B. write data and update index HoA / /C. sort index HoA and Save it to IDX.txt file/ As time goes by, I find the IDX.txt is larger than 100M It is very slow when I load IDX.txt and search HoA (grep, sort ). It is necessary to hold Index HoA when program is running, Is there any better way to go through this problem? I am wondering whether Cache module is a better solution, maybe any other module? thanks
