|
||||
Time series implementation in Go.
|
||||
|
||||
It is used in [go-trending](https://www.github.com/codesuki/go-trending) as a backend for a trending algorithm.
|
||||
The time series supports storing counts at different granularities, e.g. seconds, minutes, hours, ....<br />
|
||||
In case of go-trending the time series is configured to have recent data available at small granularity, i.e. the recent 60 seconds, and historical data available at large granularity, i.e. the last few hours, days of data.
|
||||
|
||||
A redis backend is planned.
|
||||
|
||||
* Simple interface
|
||||
* Store time series data at different granularities
|
||||
* Use your own clock implementation, e.g. for testing or similar
|
||||
|
||||
## Examples
|
||||
|
||||
### Creating a time series with default settings
|
||||
The default settings use `time.Now()` as clock and `time.Second * 60`, `time.Minute * 60` and `time.Hour * 24` as granularities.
|
||||
|
||||
```go
|
||||
import "github.com/codesuki/go-time-series"
|
||||
|
||||
...
|
||||
|
||||
ts, err := timeseries.NewTimeSeries()
|
||||
if err != nil {
|
||||
// handle error
|
||||
}
|
||||
```
|
||||
|
||||
### Creating a customized time series
|
||||
You can specify the clock and/or granularities to use. A clock must implement the `timeseries.Clock` interface.
|
||||
|
||||
```go
|
||||
import "github.com/codesuki/go-time-series"
|
||||
|
||||
...
|
||||
type clock struct {}
|
||||
func (c *clock) Now() {
|
||||
return time.Time{} // always returns the zero time
|
||||
}
|
||||
var myClock clock
|
||||
...
|
||||
|
||||
ts, err := timeseries.NewTimeSeries(
|
||||
timeseries.WithGranularities(
|
||||
[]timeseries.Granularity{
|
||||
{Granularity: time.Second, Count: 60},
|
||||
{Granularity: time.Minute, Count: 60},
|
||||
{Granularity: time.Hour, Count: 24},
|
||||
{Granularity: time.Hour * 24, Count: 7},
|
||||
}),
|
||||
timeseries.WithClock(&myClock),
|
||||
)
|
||||
if err != nil {
|
||||
// handle error
|
||||
}
|
||||
```
|
||||
|
||||
### Filling the time series
|
||||
To fill the time series with counts, e.g. events, you can use two different functions.
|
||||
|
||||
```go
|
||||
import "github.com/codesuki/go-time-series"
|
||||
|
||||
...
|
||||
|
||||
ts, err := timeseries.NewTimeSeries()
|
||||
if err != nil {
|
||||
// handle error
|
||||
}
|
||||
|
||||
ts.Increase(2) // adds 2 to the counter at the current time
|
||||
ts.IncreaseAtTime(3, time.Now().Add(-2 * time.Minute)) // adds 3 to the counter 2 minutes ago
|
||||
```
|
||||
|
||||
### Querying the time series
|
||||
The `Range()` function takes 2 arguments, i.e. the start and end of a time span.
|
||||
`Recent()` is a small helper function that just uses `clock.Now()` as `end` in `Range`.
|
||||
Please refer to the [documentation](https://godoc.org/github.com/codesuki/go-time-series) for how `Range()` works exactly. There are some details depending on what range you query and what range is available.
|
||||
|
||||
```go
|
||||
import "github.com/codesuki/go-time-series"
|
||||
|
||||
...
|
||||
|
||||
ts, err := timeseries.NewTimeSeries()
|
||||
if err != nil {
|
||||
// handle error
|
||||
}
|
||||
|
||||
ts.Increase(2) // adds 2 to the counter at the current time
|
||||
// 1s passes
|
||||
ts.Increase(3)
|
||||
// 1s passes
|
||||
|
||||
ts.Recent(5 * time.Second) // returns 5
|
||||
|
||||
ts.Range(time.Now().Add(-5 * time.Second), time.Now()) // returns 5
|
||||
```

// Explanation
|
||||
// Have several granularity buckets
|
||||
// 1s, 1m, 5m, ...
|
||||
// The buckets will be in circular arrays
|
||||
//
|
||||
// For example we could have
|
||||
// 60 1s buckets to make up 1 minute
|
||||
// 60 1m buckets to make up 1 hour
|
||||
// ...
|
||||
// This would enable us to get the last 1 minute data at 1s granularity (every second)
|
||||
//
|
||||
// Date ranges are [start, end[
|
||||
//
|
||||
// Put:
|
||||
// Every time an event comes we add it to all corresponding buckets
|
||||
//
|
||||
// Example:
|
||||
// Event time = 12:00:00
|
||||
// 1s bucket = 12:00:00
|
||||
// 1m bucket = 12:00:00
|
||||
// 5m bucket = 12:00:00
|
||||
//
|
||||
// Event time = 12:00:01
|
||||
// 1s bucket = 12:00:01
|
||||
// 1m bucket = 12:00:00
|
||||
// 5m bucket = 12:00:00
|
||||
//
|
||||
// Event time = 12:01:01
|
||||
// 1s bucket = 12:01:01
|
||||
// 1m bucket = 12:01:00
|
||||
// 5m bucket = 12:00:00
|
||||
//
|
||||
// Fetch:
|
||||
// Given a time span we try to find the buckets with the finest granularity
|
||||
// to satisfy the time span and return the sum of their contents
|
||||
//
|
||||
// Example:
|
||||
// Now = 12:05:30
|
||||
// Time span = 12:05:00 - 12:05:02
|
||||
// Return sum of 1s buckets 0,1

|

// Now = 12:10:00
|

// Time span = 12:05:00 - 12:07:00
|

// Return sum of 1m buckets 5,6
|

//
|

// Now = 12:10:00

// Time span = 12:00:00 - 12:10:00 (last 10 minutes)

//
|

// Now = 12:10:01

// Time span = 12:05:01 - 12:10:01 (last 5 minutes)

Trending algorithm based on the article [Trending at Instagram](http://instagram-engineering.tumblr.com/post/122961624217/trending-at-instagram). To detect trends an items current behavior is compared to its usual behavior. The more it differes the higher / lower the score. Items will start trending if the current usage is higher than its average usage. To avoid items quickly become non-trending again the scores are smoothed.
|
||||
|
||||
* Configurable and simple to use
|
||||
* Use your own clock implementation, e.g. for testing or similar
|
||||
* Use any time series implementation as backend that implements the TimeSeries interface
|
||||
|
||||
### Details
|
||||
Uses a [time series](https://www.github.com/codesuki/go-time-series) for each item to keep track of its past behavior and get recent behavior with small granularity. Computes the [Kullback-Leibler divergence](https://en.wikipedia.org/wiki/Kullback%E2%80%93Leibler_divergence) between recent behavior and expected, i.e. past, bahavior. Then blends the current item score with its past [decayed](https://en.wikipedia.org/wiki/Exponential_decay) maximum score to get the final score.
|
||||
|
||||
## Examples
|
||||
|
||||
### Creating a default scorer
|
||||
```go
|
||||
import "github.com/codesuki/go-trending"
|
||||
|
||||
...
|
||||
|
||||
scorer := trending.NewScorer()
|
||||
```
|
||||
|
||||
### Creating a customized scorer
|
||||
**Parameters**
|
||||
* **Time series:** is used for creating the backing `TimeSeries` objects
|
||||
* **Half-life:** controls how long an item is trending after the activity went back to normal.
|
||||
* **Recent duration:** controls how much data is used to compute the current state. If there is not much activity try looking at larger duration.
|
||||
* **Storage duration:** controls how much historical data is used. Trends older than the storage duration won't have any effect on the computation. The time series in use should have at least as much storage duration as specified here.
|
||||
|
||||
```go
|
||||
import "github.com/codesuki/go-trending"
|
||||
|
||||
...
|
||||
func NewTimeSeries(id string) TimeSeries {
|
||||
// create time series that satisfies the TimeSeries interface
|
||||
return timeSeries
|
||||
}
|
||||
|
||||
...
|
||||
|
||||
scorer := trending.NewScorer(
|
||||
WithTimeSeries(NewTimeSeries),
|
||||
WithHalflife(time.Hour),
|
||||
WithRecentDuration(time.Minute),
|
||||
WithStorageDuration(7 * 24 * time.Hour),
|
||||
)
|
||||
```
|
||||
|
||||
|
||||
### Using the scorer
|
||||
```go
|
||||
import "github.com/codesuki/go-trending"
|
||||
|
||||
...
|
||||
|
||||
scorer := trending.NewScorer()
|
||||
|
||||
scorer.AddEvent("id", time)
|
||||
// add more events. maybe using an event stream.
|
||||
|
||||
...
|
||||
|
||||
trendingItems := scorer.Score()
|
||||
```
