# Колонково Съхранение (Columnar)
|
|
|
|
Колонково-ориентирано съхранение за аналитични заявки и агрегации.
|
|
|
|
## Употреба
|
|
|
|
```nim
|
|
import barabadb/core/columnar
|
|
|
|
var batch = newColumnBatch()
|
|
var ageCol = batch.addInt64Col("age")
|
|
var nameCol = batch.addStringCol("name")
|
|
|
|
ageCol.appendInt64(25)
|
|
nameCol.appendString("Alice")
|
|
```
|
|
|
|
## Агрегации
|
|
|
|
```nim
|
|
echo ageCol.sumInt64()
|
|
echo ageCol.avgInt64()
|
|
echo ageCol.minInt64()
|
|
echo ageCol.maxInt64()
|
|
echo ageCol.count()
|
|
```
|
|
|
|
## Кодиране
|
|
|
|
### RLE (Run-Length Encoding)
|
|
|
|
```nim
|
|
let rle = rleEncode(@[1'i64, 1, 1, 2, 2, 3])
|
|
```
|
|
|
|
### Dictionary Encoding
|
|
|
|
```nim
|
|
let dict = dictEncode(@["apple", "banana", "apple"])
|
|
```
|
|
|
|
