Spark Dataframe是否有与Panda的合并指示器等效的选项？

# 导入必要的库
from pyspark.sql import SparkSession

# 创建SparkSession
spark = SparkSession.builder.getOrCreate()

# 创建两个DataFrame
df1 = spark.createDataFrame([(1, "Alice"), (2, "Bob"), (3, "Charlie")], ["id", "name"])
df2 = spark.createDataFrame([(1, 25), (2, 30), (4, 35)], ["id", "age"])

# 使用join操作合并两个DataFrame
merged_df = df1.join(df2, on="id", how="inner")

# 显示合并后的结果
merged_df.show()
