Examples

Contoh 1: Menghitung nilai minimum kolom numerik

import pyspark.sql.functions as sf
df = spark.range(10)
df.select(sf.min(df.id)).show()

+-------+
|min(id)|
+-------+
|      0|
+-------+

Contoh 2: Menghitung nilai minimum kolom string

import pyspark.sql.functions as sf
df = spark.createDataFrame([("Alice",), ("Bob",), ("Charlie",)], ["name"])
df.select(sf.min("name")).show()

+---------+
|min(name)|
+---------+
|    Alice|
+---------+

Contoh 3: Menghitung nilai minimum kolom dengan nilai null

import pyspark.sql.functions as sf
df = spark.createDataFrame([(1,), (None,), (3,)], ["value"])
df.select(sf.min("value")).show()

+----------+
|min(value)|
+----------+
|         1|
+----------+

Contoh 4: Menghitung nilai minimum kolom dalam DataFrame yang dikelompokkan

import pyspark.sql.functions as sf
df = spark.createDataFrame([("Alice", 1), ("Alice", 2), ("Bob", 3)], ["name", "value"])
df.groupBy("name").agg(sf.min("value")).show()

+-----+----------+
| name|min(value)|
+-----+----------+
|Alice|         1|
|  Bob|         3|
+-----+----------+

Contoh 5: Menghitung nilai minimum kolom dalam DataFrame dengan beberapa kolom

import pyspark.sql.functions as sf
df = spark.createDataFrame(
    [("Alice", 1, 100), ("Bob", 2, 200), ("Charlie", 3, 300)],
    ["name", "value1", "value2"])
df.select(sf.min("value1"), sf.min("value2")).show()

+-----------+-----------+
|min(value1)|min(value2)|
+-----------+-----------+
|          1|        100|
