Revision 1ea83c5de98aec22bc946236094156ba14ed719e authored by Anand Ananthabhotla on 12 July 2018, 06:36:36 UTC, committed by Facebook Github Bot on 12 July 2018, 06:41:58 UTC
Summary: This test routinely exceeds the FB contbuild test timeout of 10 minutes, due to the large number of iterations. The large number (mainly due to 100 randomly selected window sizes) does not seem to add any value. Reduce it to allow the test to finish in < 10 mins.

run_flash_bench.sh
#!/usr/bin/env bash
# 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").

# Notes on test sequence:
# step 1) Setup database via sequential fill followed by overwrite to fragment it.
# Done without setting DURATION to make sure that overwrite does $num_keys writes
# step 2) read-only tests for all levels of concurrency requested
# step 3) non read-only tests for all levels of concurrency requested
# step 4) merge tests for all levels of concurrency requested. These must come last.
