-Notices For Client Library Development
-==========
-
-Currently C++ and Java are supported to visit Pegasus cluster. You may want to refer to [C++ documentations](https://github.com/XiaoMi/pegasus/wiki/Cpp%E5%AE%A2%E6%88%B7%E7%AB%AF%E6%96%87%E6%A1%A3) or [Java documentation](https://github.com/XiaoMi/pegasus/wiki/Java%E5%AE%A2%E6%88%B7%E7%AB%AF%E6%96%87%E6%A1%A3) for details.
-
-Here we give some notices on the client library, which may be helpful to development of other language bindings.
-
-## message protocol
-
-### request to server
-
-Message format sent to some single server of Pegasus Cluster:
-
-`
-(A special header of 48 bytes) + (body)
-`
-
-#### header
-
-The 48-byte header consists of:
-
-| bytes | type | comments
-|-------| -----|--------- |
-| 0~3 | "THFT" | (header_type)
-| 4~7 | 32bit int | header version
-| 8~11 | 32bit int | header_length
-| 12~15 | 32bit int | header_crc32
-| 16~19 | 32bit int | body_length
-| 20~23 | 32bit int | body_crc32
-| 24~27 | 32bit int | app_id (rDSN related concept)
-| 28~31 | 32bit int | partition_index (rDSN related concept)
-| 32~35 | 32bit int | client_timeout
-| 36~39 | 32bit int | thread_hash (rDSN related concept)
-| 40~47 | 64bit long | partition_hash (rDSN related concept)
-
-Some notes on the above "header":
- * all ints/long in the header are in network order.
- * if send request to meta server, the app\_id & partition\_index should set to 0; if request is to replica server, the fields should be set to the target replica.
- * pegasus server may use client_timeout to do some optimization. Say, a server may simply discard a request if it has expired when server receives it
- * thread\_hash = app\_id * 7919 + partition\_index, it is used for server to decide in which thread to queue the request.
- * partition_hash should set to 0, it's only a useful field for RPC client of rDSN framework.
-
-#### body
-the body is a standard thrift struct in binary protocol:
-
-TMessageBegin + args + TMessageEnd.
-
-You should write a thrift "TMessage" in TMessageBegin, the structure of TMessage is:
-* name: the RPC name (please refer to Java client for detail)
-* type: TMessage.CALL
-* seqid: the seqid int
-
-### response from server
-
-response got from pegasus server:
-
-`
-total_response_length(4 bytes) +  error_code_thrift_struct + response_body
-`
-
-Some notes on the above response:
-
-* **error_code_thrift_struct** is an error_code struct in thrift binary protocol, usually it indicates some error of service status than the response of some specific rpc call. For example, for a meta server, this error may indicate "the meta server is not leader"; for a read/write request to replica server, this error may indicate that the replica server is not a primary or don't serve the partition"
-* **response_body** is a standard thrift rpc response of the rpc call, with the format as follows:
-  * TMessageBegin: rpc_name, TMessage.T_REPLY, seqid_integer
-  * response_args
-  * TMessageEnd
-
-## write/read request process
-
-You can refer to [TableHandler.java](https://github.com/XiaoMi/pegasus-java-client/blob/thrift-0.11.0-inlined/src/main/java/com/xiaomi/infra/pegasus/rpc/async/TableHandler.java) for the detailed RPC process in write/read request RPCs.
-
-## how to generate code in thrift
-
-There are [3 IDL files](https://github.com/XiaoMi/pegasus-java-client/tree/thrift-0.11.0-inlined/idl) for RPC client:
-* base.thrift: a placeholder for rDSN specific structures(blob, error\_code, task\_code, RPC_address, gpid), you may use thrift to generate a sketch, and implement the details all by yourself.
-* replication.thrift: messages and RPCs used for communicate with meta server. Using generated code is ok.
-* rrdb.thrift: messages and RPCs used for communicate with replica server. Using generated code is ok.
-
-Due to some history reasons, RPC names defined in the IDL can't be recognized by server right now. A proper name should be set manually, please refer to [operators](https://github.com/XiaoMi/pegasus-java-client/tree/thrift-0.11.0-inlined/src/main/java/com/xiaomi/infra/pegasus/operator) for details. Besides, you may also need to refer
-to [base](https://github.com/XiaoMi/pegasus-java-client/tree/thrift-0.11.0-inlined/src/main/java/com/xiaomi/infra/pegasus/base) for how to implement serialization for rDSN specific structures.

-Installing Pegasus
-===========
-
-Currently Pegasus can only be installed from source. Binary package and docker image is coming soon.
-
-## Prerequisites and Requirements
-
-### Hardware
-
-Pegasus can be deployed in standalone mode which runs all the pegasus jobs as different processes on a single host, or in distributed mode which runs different jobs on different hosts. For distributed mode, more than one hosts are need:
-
-* One or more hosts to run zookeeper. We need zookeeper to make the cluster metadata persistence. For a fault tolerant zookeeper cluster, at least 3 are necessary.
-* One or more hosts to run Pegasus meta-server. At least 2 are needed for fault tolerance. You may share hosts between meta-server and zookeeper.
-* At least 3 hosts to run Pegasus replica-server.
-
-### Operating System requirements
-
-* Linux: CentOS 7, Ubuntu 14.04(Trusty)
-* macOS: not supported
-* Microsoft Windows: not supported
-
-## Build Pegasus from source
-
-Please notice that Pegasus can not be built until the following packages meet the version requirements:
-
-* Compiler: the gcc version must >= 4.8 && < 8. If you use other compilers, please make sure that C++14 is supported.
-* CMake: must >= 3.5.2
-* Boost: must >= 1.58
-
-#### Install the dependencies
-
-For Ubuntu:
-
-```
-sudo apt-get install build-essential cmake libboost-all-dev libaio-dev libsnappy-dev libbz2-dev libtool libgflags-dev zlib1g zlib1g.dev patch unzip automake libssl-dev liblz4-dev libzstd-dev
-```
-To start onebox:
-```
-sudo apt-get install default-jre netcat
-```
-For CentOS:
-```
-yum -y install cmake boost-devel libaio-devel snappy-devel bzip2-devel zlib-devel lz4-devel automake libtool patch unzip openssl-devel python-devel libzstd-devel
-```
-Zstd may not available in the default EPEL. To install the EPEL repository on CentOS-7/6, simply type:
-```
-yum install epel-release
-```
-To start onebox:
-```
-yum install java-1.8.0-openjdk nmap-ncat.x86_64
-```
-
-Please make sure you install the proper version of GCC, CMake and Boost.
-
-#### Build
-
-1. clone Pegasus and its all subprojects:
-
-   ```
-   git clone https://github.com/xiaomi/pegasus.git --recursive
-   ```
-2. build
-
-   ```
-   cd pegasus && ./run.sh build
-   ```
-   if Boost is installed at some custom path , please tell the build script the install path of Boost:
-
-   ```
-   ./run.sh build -b /your/boost/installation/path
-   ```
-
-Generally, the build process of Pegasus consists of 4 parts:
-
-1. Download the thirdparty dependencies to "rdsn/thirdparty" and build them, and the output headers/libraries/binaries are installed in "rdsn/thirdparty/output".
-2. build the rdsn project, which is a dependency of our KV storage. The output headers/libraries/binaries are installed in "rdsn/builder/output". The build script will create a symbolic link "DSN_ROOT" in the pegasus project root.
-3. build rocksdb in "rocksdb" dir, which is modified from [facebook/rocksdb](https://github.com/facebook/rocksdb)
-4. build pegasus's KV-layer in "src".
-
-**Please make sure the thirdparty are successfully downloaded and built before subsequent parts**.
-
-####  Common Build Problems
-* fatal error: <some_thirdparty_header_files>.h: No such file or directory
-
-This means that Third Party Building did not complete correctly and did not generate the header files.
-
-Rerun `./run.sh build` with `--clear_thirdparty`.
-
-## Run in standalone mode
-
-You can play with pegasus with a **onebox** cluster:
-
-```
-./run.sh start_onebox
-```
-
-When running onebox cluster, all pegasus jobs are running in local host: 
-
-* zookeeper: start a zookeeper process with port 22181
-* meta-server: start several meta-server processes
-* replica-server: start several replica-server processes
-
-You can also check the state of onebox cluster:
-
-```
-./run.sh list_onebox
-```
-
-Stop the onebox cluster:
-
-```
-./run.sh stop_onebox
-```
-
-Clean the onebox cluster:
-
-```
-./run.sh clear_onebox
-```
-
-## Interactive shell
-
-Pegasus provides a shell tool to interact with the cluster. To start the shell, run:
-```
-./run.sh shell
-```
-
-or specify different cluster meta-server address list:
-```
-./run.sh shell --cluster 127.0.0.1:34601,127.0.0.1:34602
-```
-
-Using the shell, you can do lots of things including:
-
-* get cluster information and statistics
-* create/drop/list tables (we name it app)
-* get/set/del/scan data
-* migrate replicas from node to node
-* send remote commands to server
-* dump mutation log and sstable files
-
-## Running test
-
-Run the unit test by:
-```
-./run.sh test
-```
-
-or run the killing test by:
-```
-./run.sh start_kill_test
-```
-
-## Benchmark
-
-You can start a benchmark client quickly (needs onebox cluster already started):
-```
-./run.sh bench
-```
-
-or start a series of benchmark tests:
-```
-./scripts/pegasus_bench_run.sh
-```
-
-Attention: this bench tool depends on gflags, so it would not work if gflags library
-is not installed when building Pegasus.
