Parallel and Distributed Storage

A parallel storage file system is a sort of clustered file system. A clustered file system is a storage system shared by multiple devices simultaneously.

Question

heap files (using lists of pages and a directory
of pages) discussed in the text.
1. Describe them briefly and explain the
trade-offs. Which organization would you
choose if records are variable in length?
2. Can you suggest a single page format to
implement both internal file organizations?

Consider a database for an airline that employs "snapshot isolation" as an example. Non-serializable executions may be acceptable if the overall performance of the airline is improved.
You are given a collection of N non-empty strings, denoted by S₁, S₂,..., Sn. Then you are given N-1 operations which you execute in the order they are given. The įth operation is has the following format: 'a b' (1-based indexing, without the quotes), which means that you have to make the following changes: 1. Sa = Sa+ Sb, i.e. concatenate ath string and 6th string and store the result in ath string, 2. S = "", i.e. make the 6th string empty, after doing the previous step. You are ensured that after the ith operation, there will be no future operation that will be accessing S. Given these operations to join strings, print the last string that will remain at the end of this process. Input The first line contains an integer N (1 ≤N≤ 105) denoting the number of strings given. Each of the next N lines contains a string denoting the S₁. All the characters in the string S, are lowercase alphabets from 'a' to 'z'. The total number of characters over all the strings is at most 106, i.e Σ₁|S₁|…
27. Colton is working on the data structure that is to be used by Universal Bank to store the transactions of users to be displayed on their website interface when the user logs in. Load time needs to be fast, so a fast insertion time is mandatory. The data stored and loaded from the server is already in sorted order.so it is read into Colton's program in sorted order. The data structure does not need fast search times, and no deletion is allowed. The transactions will be shown on the website in order. What data structure would work well for Colton?
Please answers fast Implement an external sort, which uses intermediate files to sort files bigger than main memory. Why Mergesort is a better algorithm than heapsort or quicksort to base such an implementation on? Test your program both on files with small records and on files with large records.
