mizar

Mizar is a fork of RocksDB v9.2.0 with the following changes:

• promote containers performance by using turbo
• built with EA(Elastic Architecture) environment
• to avoid conflict with RocksDB, the library name is changed to mizar
• change license to GAPL-3.0(GNU AFFERO GENERAL PUBLIC LICENSE)

note that mizar may not run on windows, we focus on server-side performance and stability on linux. although it may run on windows, we do not test it on windows.

Build

requirements:

• cmake >= 3.24
• gcc >= 9.3.0

install gottingen/essential

the dependencies of mizar are installed to /opt/EA/inf, such as zlib, snappy, zstd, they are all static libraries. so the program executable file is independent of the system environment.

git clone https://github.com/goettingen/essential.git
cd essential
./install.sh

install gottingen/turbo

git clone https://github.com/goettingen/turbo.git
cd turbo
git checkout v0.5.6
mkdir build
cd build
cmake ..
make -j 6
make pacakge
sudo dpkg -i package/turbo-*.deb # or rpm -ivh package/turbo*.rpm

using pacakge to install is convenient for uninstalling.

build mizar

git clone https://github.com/goettingen/mizar.git
cd mizar
mkdir build
cd build
cmake ..
make -j 6

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.
