TeaFiles.Net - Time Series Storage in Files | ||
=========================================== | ||
|
||
Use TeaFiles.Net to create, read and write files holding time series data. | ||
|
||
|
||
|
||
Features | ||
-------- | ||
|
||
* highest **performance** | ||
* very **simple** | ||
* **versatile** - open TeaFiles with C++, C#, Python, R, on any platform | ||
|
||
|
||
|
||
TeaFiles = Binary Data + Header | ||
------------------------------- | ||
|
||
* TeaFile is a **file format** | ||
* to store **time series** | ||
* as binary **flat files** | ||
* optional **header** holds a **description** of file contents (metadata) | ||
* including a description of the **item type layout** (schema) | ||
* simple format, designed to make API writing very easy | ||
* http://www.discretelogics.com published the file format and | ||
* releases APIs for C#, C++, Python under the GPL | ||
|
||
|
||
|
||
Performance | ||
----------- | ||
> 250 Mio Items per seconds cold | ||
> 465 Mio Items per seconds warm | ||

||
```C# | ||
// define time series item type | ||
struct Tick | ||
{ | ||
public Time Time; | ||
public double Price; | ||
public int Volume; | ||
} | ||
// create file and write values | ||
using (var tf = TeaFile<Tick>.Create("acme.tea")) | ||
{ | ||
tf.Write(new Tick { Price = 5, Time = DateTime.Now, Volume = 700 }); | ||
tf.Write(new Tick { Price = 15, Time = DateTime.Now.AddHours(1), Volume = 1700 }); | ||
// ... | ||
} | ||
// sum the prices of all items in the file | ||
using (var tf = TeaFile<Tick>.OpenRead("acme.tea")) | ||
{ | ||
return tf.Items.Sum(item => item.Price); | ||
