# REQUIRE: benchmark_leveldb.sh exists in the current directory
# After execution of this script, log files are generated in $output_dir.
# report.txt provides a high level statistics
#
# This should be used with the LevelDB fork listed here to use additional test options.
# For more details on the changes see the blog post listed below.
# https://github.com/mdcallag/leveldb-1
# http://smalldatum.blogspot.com/2015/04/comparing-leveldb-and-rocksdb-take-2.html
#
# This should be run from the parent of the tools directory. The command line is:
# [$env_vars] tools/run_flash_bench.sh [list-of-threads]
#
# This runs a sequence of tests in the following sequence:
# step 1) load - bulkload, compact, fillseq, overwrite
# step 2) read-only for each number of threads
# step 3) read-write for each number of threads
#
# The list of threads is optional and when not set is equivalent to "24".
# Were list-of-threads specified as "1 2 4" then the tests in steps 2, 3 and
# 4 above would be repeated for 1, 2 and 4 threads. The tests in step 1 are
# only run for 1 thread.
# Test output is written to $OUTPUT_DIR, currently /tmp/output. The performance
# summary is in $OUTPUT_DIR/report.txt. There is one file in $OUTPUT_DIR per
# test and the tests are listed below.
#
# The environment variables are also optional. The variables are:
# NKEYS - number of key/value pairs to load
# NWRITESPERSEC - the writes/second rate limit for the *whilewriting* tests.
# If this is too large then the non-writer threads can get
# starved.
# VAL_SIZE - the length of the value in the key/value pairs loaded.
# You can estimate the size of the test database from this,
# NKEYS and the compression rate (--compression_ratio) set
# in tools/benchmark_leveldb.sh
# BLOCK_LENGTH - value for db_bench --block_size
# CACHE_BYTES - the size of the RocksDB block cache in bytes
# DATA_DIR - directory in which to create database files
# DO_SETUP - when set to 0 then a backup of the database is copied from
# $DATA_DIR.bak to $DATA_DIR and the load tests from step 1
# This allows tests from steps 2, 3 to be repeated faster.
# SAVE_SETUP - saves a copy of the database at the end of step 1 to
# $DATA_DIR.bak.
# Size constants
