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

CircleCI Status

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.
