无法在数据块上创建功能 table

Question

from pyspark.sql import SparkSession, Row
from datetime import date

spark = SparkSession.builder.getOrCreate()

tempDf = spark.createDataFrame([
    Row(date=date(2022,1,22), average=40.12),
    Row(date=date(2022,1,23), average=41.32),
    Row(date=date(2022,1,24), average=44.23),
    Row(date=date(2022,1,26), average=45.34),
    Row(date=date(2022,2,7), average=32.56),
    Row(date=date(2022,2,10), average=43.78),
    Row(date=date(2022,2,12), average=37.89)
])

%sql CREATE DATABASE IF NOT EXISTS feature_store

from databricks import feature_store
fs = feature_store.FeatureStoreClient()

fs.create_feature_table(
    name="feature_store.uk_avg_temperature_feature",
    keys=["date"],
    features_df=tempDf,
    description="UK Temperature Features"
)

尝试创建功能时出现以下错误 table -

2022/03/04 12:02:40 ERROR databricks.feature_store.utils.rest_utils: 
API request to https://community.cloud.databricks.com/api/2.0/feature-store/feature-tables/get 
failed with code 503 != 200, retrying up to 2 more times. 
API response body: 
{"error_code":"TEMPORARILY_UNAVAILABLE","message":"The service at /api/2.0/feature-store/feature-tables/get is temporarily unavailable. Please try again later."}

注意 - 我使用的是 databricks 社区版。

Answer 1

我认为 databricks 社区版无法处理特征存储功能。它甚至没有侧面菜单中的 icon/feature。

如果您找到解决方法，请告诉我！
