# System integration test script.
|
|
# This script runs a single process that tests the full functionality of
|
|
# the system. The database under test contains nfiles files. Each process
|
|
# randomly generates a key and some data. Both keys and data are bimodally
|
|
# distributed between small keys (1-10 characters) and large keys (the avg
|
|
# length is indicated via the command line parameter.
|
|
# The process then decides on a replication factor between 1 and nfiles.
|
|
# It writes the key and data to that many files and tacks on the file ids
|
|
# of the files it writes to the data string. For example, let's say that
|
|
# I randomly generate the key dog and data cat. Then I pick a replication
|
|
# factor of 3. I pick 3 files from the set of n (say 1, 3, and 5). I then
|
|
# rewrite the data as 1:3:5:cat. I begin a transaction, add the key/data
|
|
# pair to each file and then commit. Notice that I may generate replication
|
|
# of the form 1:3:3:cat in which case I simply add a duplicate to file 3.
|
|
#
|
|
# Usage: sysscript dir nfiles key_avg data_avg
|
|
#
|
|
# dir: DB_HOME directory
|
|
# nfiles: number of files in the set
|
|
# key_avg: average big key size
|
|
# data_avg: average big data size
