Summary: After closely working with Mark, Siying, and Yueh-Hsuan this set of changes reflects the updates needed to measure RocksDB subcompaction performance in a correct manner. The essence of the benchmark is executing `fillrandom` followed by `compact` with the correct set of options for various number of subcompactions specified. Test Plan: Tested internally to verify correctness and reliability.

# REQUIRE: benchmark.sh exists in the current directory
|
|
# After execution of this script, log files are generated in $output_dir.
|
|
# report.txt provides a high level statistics
|
|
|
|
# This should be run from the parent of the tools directory. The command line is:
|
|
# [$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
|
|
# step 4) merge 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
|
|
# BG_MBWRITEPERSEC - write rate limit in MB/second for tests in which
|
|
# there is one thread doing writes and stats are
|
|
# reported for read threads. "BG" stands for background.
|
|
# If this is too large then the non-writer threads can get
|
|
# starved. This is used for the "readwhile" tests.
|
|
# FG_MBWRITEPERSEC - write rate limit in MB/second for tests like overwrite
|
|
# where stats are reported for the write threads.
|
|
# NSECONDS - number of seconds for which to run each test in steps 2,
|
|
# 3 and 4. There are currently 15 tests in those steps and
|
|
# they are repeated for each entry in list-of-threads so
|
|
# this variable lets you control the total duration to
|
|
# finish the benchmark.
|
|
# RANGE_LIMIT - the number of rows to read per range query for tests that
|
|
# do range queries.
|
|
# 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.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
|
|
# LOG_DIR - directory in which to create WAL files, may be the same
|
|
# as DATA_DIR
|
|
# 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
|
|
# The WAL directory is also copied from a backup if
|
|
# DATA_DIR != LOG_DIR. This allows tests from steps 2, 3, 4
|
|
# to be repeated faster.
|
|
# SAVE_SETUP - saves a copy of the database at the end of step 1 to
|
|
# $DATA_DIR.bak. When LOG_DIR != DATA_DIR then it is copied
|
|
# to $LOG_DIR.bak.
|
|
# SKIP_LOW_PRI_TESTS - skip some of the tests which aren't crucial for getting
|
|
# actionable benchmarking data (look for keywords "bulkload",
|
|
# "sync=1", and "while merging").
