Revision 8ad0fcdf99003caa07cd6aaeba0347e1a92da622 authored by Siying Dong on 27 February 2017, 20:19:23 UTC, committed by Facebook Github Bot on 27 February 2017, 20:24:11 UTC
Summary: Separate a smal subset of tests in DBTest to DBBasicTest. Tests in DBTest don't have to run in CI tests on platforms like OSX, as long as they are covered by Linux. Closes https://github.com/facebook/rocksdb/pull/1924 Differential Revision: D4616702 Pulled By: siying fbshipit-source-id: 13e6549

run_leveldb.sh
#!/bin/bash
# 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.

#
# 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
