Nipo is a powerful, fast, multi-thread, clustered and in-memory key-value database, with ability to configure token and acl on commands and key-regexes written by GO. With several mathematical and aggregation functionalities on batch of keys and values.
Fast
Nipo will give you up to 15K OPS in single mode and up to 2.5K OPS in cluster mode with 2 slaves.
Multi-Thread
Nipo's architecture is multi-thread and you can define core and threads in your config file.
Clustered
Nipo supports several slaves and guaranties your slaves synchronization. It will automatically sync slave after comming up. You can ask your cluster status. The healthcheck interval could be configured in millisecond.
In-Memory
Nipo is in-memory database and data will be lost if service stops.

Global section defines some global parameters
authorization (string): [true/false]
Defines that the clients must work with token or not. If set "true" you have to define users section
master (string): [true/false]
Defines that this server has some slaves. If set "true" you have to define slaves section
checkinterval (int):
Defines the interval of slaves healthcheck in milliseconds
global:
authorization: false
master: true
checkinterval: 1000
Slave section defines parameter about slaves of this server
id (int) : defines the id of slave. Master will sync the slaves by id priority.
ip (string) : is the IP of slave
port (string) : is the listen port of destination IP
authorization (string) : [true/false] defines if the destination slave uses token or not
token (string) : in case of authorization is true, you need to define token
slaves:
- slave:
id : 1
ip : 127.0.0.1
port : 2324
authorization: false
token: 061b30a7-1a12-4280-8e3c-6bc9a19b1683
- slave:
id : 2
ip : 127.0.0.1
port : 2325
authorization: false
token: 061b30a7-1a12-4280-8e3c-6bc9a19b1683
Proc section defines parameters for multi-threading and multi-processing
cores (int) : the count of cores you want to used by nipo
threads (int) : the count of threads you want to created by nipo
NOTE : the best practice is using threads two times of cores
proc:
cores: 2
threads: 4
At this section you can configure your server side listen IP and PORT, currently only TCP is allowed.
listen:
ip: 0.0.0.0
port: 2323
protocol: tcp
Log section defines parameters for logging
level (int) :
0 - no log
1 - info
2 - debug
path (string) : defines the path of log file
log:
level: 1
path: "/tmp/nipo.log"
Users section defines parameters for authorization. If authorization in global section is true, this section had to be defined you can define several users
name (string) : just is metadata for name of user
token (string) : used for authorization
keys (string) : the regex of keys which user should have access.
if you have several regexes you can separate them with delimiter "||"
cmds (string) : the list of commands that user should have access to execute
if you have several commands you can separate them with delimiter "||"
users:
- user:
name: admin
token: 061b30a7-1a12-4280-8e3c-6bc9a19b1683
keys: .*
cmds: all
- user:
name: readonly
token: 0517376d-49c1-40eb-a8fc-fd73b70a4ce9
keys: name.*||.*log.*
cmds: get||select||avg
