This function analyzes the compressability of the keys using a single huffman tree. For example, ``` >debug POPULATE 1000000 keyabcdef 10 OK > debug compression 1) max_symbol 2) (integer) 121 3) max_bits 4) (integer) 5 5) raw_size 6) (integer) 7861817 7) compressed_size 8) (integer) 4372270 9) ratio 10) "0.5561398847111297" ``` Signed-off-by: Roman Gershman <roman@dragonflydb.io>

# Build DragonflyDB From Source
|
|
|
|
## Running the server
|
|
|
|
Dragonfly runs on linux. We advise running it on linux version 5.11 or later
|
|
but you can also run Dragonfly on older kernels as well.
|
|
|
|
> :warning: **Dragonfly releases are compiled with LTO (link time optimization)**:
|
|
Depending on the workload this can notably improve performance. If you want to
|
|
benchmark Dragonfly or use it in production, you should enable LTO by giving
|
|
`blaze.sh` the `-DCMAKE_CXX_FLAGS="-flto"` argument.
|
|
|
|
## Step 1 - install dependencies
|
|
|
|
On Debian/Ubuntu:
|
|
|
|
```bash
|
|
sudo apt install ninja-build libunwind-dev libboost-context-dev libssl-dev \
|
|
autoconf-archive libtool cmake g++ bison zlib1g-dev
|
|
```
|
|
|
|
On Fedora:
|
|
|
|
```bash
|
|
sudo dnf install -y automake boost-devel g++ git cmake libtool ninja-build \
|
|
openssl-devel libunwind-devel autoconf-archive patch bison libstdc++-static
|
|
```
|
|
|
|
On openSUSE:
|
|
|
|
```bash
|
|
sudo zypper install automake boost-devel gcc-c++ git cmake libtool ninja \
|
|
openssl-devel libunwind-devel autoconf-archive patch bison \
|
|
libboost_context-devel libboost_system-devel
|
|
```
|
|
|
|
On FreeBSD:
|
|
|
|
```bash
|
|
pkg install -y git bash cmake ninja libunwind boost-libs autoconf automake libtool gmake bison
|
|
```
|
|
|
|
## Step 2 - clone the project
|
|
|
|
```bash
|
|
git clone --recursive https://github.com/dragonflydb/dragonfly && cd dragonfly
|
|
```
|
|
|
|
## Step 3 - configure & build it
|
|
|
|
```bash
|
|
# Configure the build
|
|
./helio/blaze.sh -release
|
|
|
|
# Build
|
|
cd build-opt && ninja dragonfly
|
|
|
|
```
|
|
|
|
## Step 4 - voilà
|
|
|
|
```bash
|
|
# Run
|
|
./dragonfly --alsologtostderr
|
|
|
|
```
|
|
|
|
Dragonfly DB will answer to both `http` and `redis` requests out of the box!
|
|
|
|
You can use `redis-cli` to connect to `localhost:6379` or open a browser and visit `http://localhost:6379`
|
|
|
|
## Step 5
|
|
|
|
Connect with a redis client
|
|
|
|
```bash
|
|
redis-cli
|
|
127.0.0.1:6379> set hello world
|
|
OK
|
|
127.0.0.1:6379> keys *
|
|
1) "hello"
|
|
127.0.0.1:6379> get hello
|
|
"world"
|
|
127.0.0.1:6379>
|
|
```
|
|
|
|
## Step 6
|
|
|
|
Continue being great and build your app with the power of DragonflyDB!
