Cacheserver
- in memory tsdb
Capability
- store 20M series with 2 hours data in memory (use less than 100GB memory)
Architecture
How to Build && Run
go get -u -v github.com/n4mine/cacheserver
cd $GOPATH/github.com/n4mine/cacheserver
make
./cacheserver
How to Push && Get data
For debug/development
Push data
use series1 as name
curl -s -XPOST "http://127.0.0.1:7000/pushdata?name=series1&ts=$(date +%s)&value=$(shuf -i 0-100 -n1)"
Get data info
curl -s 'http://127.0.0.1:7000/getinfo?name=series1'
resp:
{
"duration": 28,
"newest": 1567001322,
"oldest": 1567001294
}
Get data
curl -s 'http://127.0.0.1:7000/getdata?name=series1&from=1567001294&to=1567001322'
resp:
{
"1567001294": 10,
"1567001295": 23,
"1567001296": 14,
"1567001319": 25,
"1567001320": 69,
"1567001321": 66,
"1567001322": 71
}
For production
- use rpc in rpc/cacheserver.go
- need to unpack data in client side
type DataResp struct {
// code == 0, normal
// code > 0, exception
Code int `msg:"code"`
Msg string `msg:"msg"`
Key string `msg:"key"`
From int64 `msg:"from"`
To int64 `msg:"to"`
Step int `msg:"step"`
RRA int `msg:"rra"`
Data []Iter `msg:"data"`
}
type Iter struct {
*tsz.Iter
}
