-description: How to build Clickhouse and run benchmark with DEFLATE_QPL Codec
----
-
-# Build Clickhouse with DEFLATE_QPL
-
-- Make sure your host machine meet the QPL required [prerequisites](https://intel.github.io/qpl/documentation/get_started_docs/installation.html#prerequisites)
-- deflate_qpl is enabled by default during cmake build. In case you accidentally change it, please double-check build flag: ENABLE_QPL=1
-
-- For generic requirements, please refer to Clickhouse generic [build instructions](/docs/en/development/build.md)
-
-# Run Benchmark with DEFLATE_QPL
-
-## Files list
-
-The folders `benchmark_sample` under [qpl-cmake](https://github.com/ClickHouse/ClickHouse/tree/master/contrib/qpl-cmake) give example to run benchmark with python scripts:
-
-`client_scripts` contains python scripts for running typical benchmark, for example:
-- `client_stressing_test.py`: The python script for query stress test with [1~4] server instances.
-- `queries_ssb.sql`: The file lists all queries for [Star Schema Benchmark](https://clickhouse.com/docs/en/getting-started/example-datasets/star-schema/)
-- `allin1_ssb.sh`: This shell script executes benchmark workflow all in one automatically.
-
-`database_files` means it will store database files according to lz4/deflate/zstd codec.
-
-## Run benchmark automatically for Star Schema:
-
-``` bash
-$ cd ./benchmark_sample/client_scripts
-$ sh run_ssb.sh
-```
-
-After complete, please check all the results in this folder:`./output/`
-
-In case you run into failure, please manually run benchmark as below sections.
-
-## Definition
-
-[CLICKHOUSE_EXE] means the path of clickhouse executable program.
-
-## Environment
-
-- CPU: Sapphire Rapid
-- OS Requirements refer to [System Requirements for QPL](https://intel.github.io/qpl/documentation/get_started_docs/installation.html#system-requirements)
-- IAA Setup refer to [Accelerator Configuration](https://intel.github.io/qpl/documentation/get_started_docs/installation.html#accelerator-configuration)
-- Install python modules:
-
-``` bash
-pip3 install clickhouse_driver numpy
-```
-
-[Self-check for IAA]
-
-``` bash
-$ accel-config list | grep -P 'iax|state'
-```
-
-Expected output like this:
-``` bash
-    "dev":"iax1",
-    "state":"enabled",
-            "state":"enabled",
-```
-
-If you see nothing output, it means IAA is not ready to work. Please check IAA setup again.
-
-## Generate raw data
-
-``` bash
-$ cd ./benchmark_sample
-$ mkdir rawdata_dir && cd rawdata_dir
-```
-
-Use [`dbgen`](https://clickhouse.com/docs/en/getting-started/example-datasets/star-schema) to generate 100 million rows data with the parameters:
--s 20
-
-The files like `*.tbl` are expected to output under `./benchmark_sample/rawdata_dir/ssb-dbgen`:
-
-## Database setup
-
-Set up database with LZ4 codec
-
-``` bash
-$ cd ./database_dir/lz4
-$ [CLICKHOUSE_EXE] server -C config_lz4.xml >&/dev/null&
-$ [CLICKHOUSE_EXE] client
-```
-
-Here you should see the message `Connected to ClickHouse server` from console which means client successfully setup connection with server.
-
-Complete below three steps mentioned in [Star Schema Benchmark](https://clickhouse.com/docs/en/getting-started/example-datasets/star-schema)
-- Creating tables in ClickHouse
-- Inserting data. Here should use `./benchmark_sample/rawdata_dir/ssb-dbgen/*.tbl` as input data.
-- Converting “star schema” to de-normalized “flat schema”
-
-Set up database with IAA Deflate codec
-
-``` bash
-$ cd ./database_dir/deflate
-$ [CLICKHOUSE_EXE] server -C config_deflate.xml >&/dev/null&

-
-``` bash
-$ cpupower idle-set -d 3
-$ cpupower frequency-set -g performance
-```
-
-- To eliminate impact of memory bound on cross sockets, we use `numactl` to bind server on one socket and client on another socket.
-- Single instance means single server connected with single client
-
-Now run benchmark for LZ4/Deflate/ZSTD respectively:

-## Benchmark with multi-instances
-
-- To reduce impact of memory bound on too much threads, We recommend run benchmark with multi-instances.
-- Multi-instance means multiple（2 or 4）servers connected with respective client.
-- The cores of one socket need to be divided equally and assigned to the servers respectively.
-- For multi-instances, must create new folder for each codec and insert dataset by following the similar steps as single instance.
-
-There are 2 differences: 
-- For client side, you need launch clickhouse with the assigned port during table creation and data insertion.
-- For server side, you need launch clickhouse with the specific xml config file in which port has been assigned. All customized xml config files for multi-instances has been provided under ./server_config.
-
-Here we assume there are 60 cores per socket and take 2 instances for example.

-
-- [TBL_FILE_NAME] represents the name of a file named with the regular expression: *. tbl under `./benchmark_sample/rawdata_dir/ssb-dbgen`.
-- `--port=9001` stands for the assigned port for server instance which is also defined in config_lz4_s2.xml/config_zstd_s2.xml/config_deflate_s2.xml. For even more instances, you need replace it with the value: 9002/9003 which stand for s3/s4 instance respectively. If you don't assign it, the port is 9000 by default which has been used by first instance.

-## Tips
-
-Each time before launch new clickhouse server, please make sure no background clickhouse process running, please check and kill old one:
-
-``` bash
-$ ps -aux| grep clickhouse
-$ kill -9 [PID]
-```
-By comparing the query list in ./client_scripts/queries_ssb.sql with official [Star Schema Benchmark](https://clickhouse.com/docs/en/getting-started/example-datasets/star-schema), you will find 3 queries are not included: Q1.2/Q1.3/Q3.4 . This is because cpu utilization% is very low <10% for these queries which means cannot demonstrate performance differences.

 - A rename can occur alongside other modifications to the file. These are listed as separate events in file_changes but with the same time. The `argMax` function has no way of distinguishing these - it picks the first value. The natural ordering of the inserts (the only means of knowing the correct order) is not maintained across the union so modified events can be selected. For example, below the `src/Functions/geometryFromColumn.h` file has several modifications before being renamed to `src/Functions/geometryConverters.h`. Our current solution may pick a Modify event as the latest change causing `src/Functions/geometryFromColumn.h` to be retained.

 The query is limited to the current files only. We list all file changes by grouping by `path` and `commit_hash`, returning the number of lines added and removed. Using a window function, we estimate the file's total size at any moment in time by performing a cumulative sum and estimating the impact of any change on file size as `lines added - lines removed`. Using this statistic, we can calculate the percentage of the file that has been added or removed for each change. Finally, we count the number of file changes that constitute a rewrite per file i.e. `(percent_add >= 0.5) AND (percent_delete >= 0.5) AND current_size > 50`. Note we require files to be more than 50 lines to avoid early contributions to a file being counted as a rewrite. This also avoids a bias to very small files, which may be more likely to be rewritten.

 We can use the same principle as [List files that were rewritten most number of time or by most of authors](#list-files-that-were-rewritten-most-number-of-time-or-by-most-of-authors) to identify rewrites but consider all files. A window function is used to compute the time between rewrites for each file. From this, we can calculate an average and median across all files.

 Several example datasets are available in Playground.
 
 You can make queries to Playground using any HTTP client, for example [curl](https://curl.haxx.se) or [wget](https://www.gnu.org/software/wget/), or set up a connection using [JDBC](../interfaces/jdbc.md) or [ODBC](../interfaces/odbc.md) drivers. More information about software products that support ClickHouse is available [here](../integrations/index.mdx).

+**Regular Expression Filtering**
+
+The messages logged can be filtered using regular expressions using `message_regexp` and `message_regexp_negative`. This can be done on a per-level basis or globally. If both a global and logger-specific pattern is specified, the global pattern is overridden (ignored) and only the logger-specific pattern applies. The positive and negative patterns are considered independently for this situation. Note: Using this feature may cause a slight slowdown in performance.
