Apache Kvrocks is a distributed key value NoSQL database that uses RocksDB as storage engine and is compatible with Redis protocol. Kvrocks intends to decrease the cost of memory and increase the capacity while compared to Redis. The design of replication and storage was inspired by rocksplicator and blackwidow.
Kvrocks has the following key features:

It is as simple as:
$ git clone https://github.com/apache/kvrocks.git $ cd kvrocks $ ./x.py build # `./x.py build -h` to check more options
To build with TLS support, you'll need OpenSSL development libraries (e.g. libssl-dev on Debian/Ubuntu) and run:
$ ./x.py build -DENABLE_OPENSSL=ON
To build with lua instead of luaJIT, run:
$ ./x.py build -DENABLE_LUAJIT=OFF
Build with debug mode, run:
# The default build type is RelWithDebInfo and its optimization level is typically -O2. # You can change it to -O0 in debug mode. $ ./x.py build -DCMAKE_BUILD_TYPE=Debug
$ ./build/kvrocks -c kvrocks.confRunning Kvrocks using Docker

Namespace is used to isolate data between users. Unlike all the Redis databases can be visited by requirepass, we use one token per namespace. requirepass is regraded as admin token, and only admin token allows to access the namespace command, as well as some commands like config, slaveof, bgsave, etc. See the Namespace page for more details.
# add token 127.0.0.1:6666> namespace add ns1 my_token OK # update token 127.0.0.1:6666> namespace set ns1 new_token OK # list namespace 127.0.0.1:6666> namespace get * 1) "ns1" 2) "new_token" 3) "__namespace" 4) "foobared" # delete namespace 127.0.0.1:6666> namespace del ns1 OK
Kvrocks implements a proxyless centralized cluster solution but its accessing method is completely compatible with Redis cluster clients. You can use Redis cluster SDKs to access the kvrocks cluster. For more details, please refer to Kvrocks Cluster Introduction.
