Summary: This adds p99.9 and p99.99 response times to the benchmark report and adds a second report, report2.txt that has tests listed in test order rather than the time in which they were run, so overwrite tests are listed for all thread counts, then update etc. Also changes fillseq to compress all levels to avoid write-amp from rewriting uncompressed files when they reach the first level to compress. Increase max_write_buffer_number to avoid stalls during fillseq and make max_background_flushes agree with max_write_buffer_number. See https://gist.github.com/mdcallag/297ff4316a25cb2988f7 for an example of the new report (report2.txt) Task ID: # Blame Rev: Test Plan: Revert Plan: Database Impact: Memcache Impact: Other Notes: EImportant: - begin *PUBLIC* platform impact section - Bugzilla: # - end platform impact - Reviewers: igor Reviewed By: igor Subscribers: dhruba Differential Revision: https://reviews.facebook.net/D36537

# 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
|
|
# NWRITESPERSEC - the writes/second rate limit for the *whilewriting* tests.
|
|
# If this is too large then the non-writer threads can get
|
|
# starved.
|
|
# 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
|
|
# 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.
|
|
