億級下ApsaraDB HBase Phoenix秒級內RT在大搜車實踐

一、前言

大搜車業務線眾多，對於數據的需求也各種各樣，本文將介紹其中之一的大搜車車商客戶實時數據需求，例如車商PC|H5端店鋪、車輛、分享等實時流量數據報表；隨著數據量級的增長，目前數據量級在億級以上，原有以mysql提供查詢服務不再適合此場景，經過多方麵的考慮，存儲最終選擇Aliyun HBase，同時為了幾乎0成本的切換，采用Phoenix On HBase Sql中間件，它管理著HBase的二級索引並且它對sql的支持友好，本文也將介紹Phoenix和HBase結合場景下的壓力測試。

二、數據係統架構

• 實時數據來源為實時采集PC|H5端訪問日誌，通過Flume收集這些日誌，並按照業務場景需求，通過流試計算清洗、過濾、統計，使用Phoenix api推送到HBase。
• 由於Phoenix管理HBase二級索引，使用Phoenix api推送數據索引表的也會被更新，這樣對於編碼成本很低。
• 原始的日誌同時會通過Flume 持久化至HDFS，方便離線計算數據分析。

• 統一通過數據網關提供業務查詢。

三、壓測

• 數據準備

  • 使用阿裏雲數據集成 服務將mysql數據導入至PHoenix，不過它使用的HBase原生api導入，所以索引數據需要在導完之後再重建。
  • 使用MapReduce的方式，這種更友好，直接導出為HFile文件，不必走HBase API，這樣會減少集群的負載以及網絡消耗，速度更快。但使用的是阿裏雲HBase，依賴的Hadoop集群不對外。
  • 使用Phoenix提供的 psql.py腳本以csv文件的方式導入。

  考慮到是一次性的工作，本次壓測數據我采用Phoenix提供的腳本的方式導入數據。

• 數據表、sql模板、索引建立

  • 表建立 參考

  CREATE TABLE FLOW.SHOP_DATA_BY_SALER_CAR_V2 (
          PK varchar primary key,
          INFO.DATE_STR BIGINT,
          INFO.STORE_ID VARCHAR,
          INFO.CAR_ID VARCHAR,
          INFO.SELLER_ID VARCHAR,
          INFO.SHARE_PV INTEGER,
          INFO.SHARE_UV INTEGER,
          INFO.FLOW_PV INTEGER,
          INFO.FLOW_UV INTEGER,
          INFO.CALL_PV INTEGER,
          INFO.CALL_UV INTEGER,
          INFO.APPOINT_PV INTEGER,
          INFO.APPOINT_UV INTEGER,
          INFO.LAST_UPDATE_TIME DATE
      ) COMPRESSION='SNAPPY',DATA_BLOCK_ENCODING='DIFF';
  

  • 模擬真實查詢sql模板，sql查詢時間範圍為1個月的數據。

      SELECT info.seller_id,
          sum(info.share_pv) as sum_share_pv,
          sum(info.flow_pv) as sum_flow_pv,
          sum(info.call_pv) as sum_call_pv,
          sum(info.appoint_pv) as sum_appoint_pv
      FROM FLOW.SHOP_DATA_BY_SALER_CAR_V2
      WHERE info.store_id = '%s'
          AND info.date >= %d
          AND info.date <= %d
      GROUP BY info.seller_id
      ORDER BY sum_share_pv DESC
  

      SELECT sum(info.share_pv) as sum_share_pv,
          sum(info.flow_pv) as sum_flow_pv,
          sum(info.call_pv) as sum_call_pv,
          sum(info.appoint_pv) as sum_appoint_pv
      FROM FLOW.SHOP_DATA_BY_SALER_CAR_V2
      WHERE info.store_id = '%s'
          AND info.date >= %d 
          AND info.date <=  %d
  

      SELECT sum(info.share_pv) as sum_share_pv,
          sum(info.flow_pv) as sum_flow_pv,
          sum(info.call_pv) as sum_call_pv,
          sum(info.appoint_pv) as sum_appoint_pv
      FROM FLOW.SHOP_DATA_BY_SALER_CAR_V2
      WHERE info.store_id = '%s'
          AND info.date >= %d 
          AND info.date <=  %d
          AND info.seller_id = '%s'
  

      SELECT info.seller_id,
          sum(info.share_pv) sum_share_pv,
          sum(info.flow_pv) sum_flow_pv
      FROM FLOW.SHOP_DATA_BY_SALER_CAR_V2
      WHERE info.car_id = '%s' 
          AND info.date >= %d 
          AND info.date <=  %d 
          AND info.share_pv <> 0
      ORDER BY info.seller_id
  

• 針對sql模板場景，建立索引表，索引類為覆蓋索引 Secondary Indexing

      CREATE INDEX SHOP_DATA_BY_SALER_CAR_V2_INDEX
      ON FLOW.SHOP_DATA_BY_SALER_CAR_V2 (INFO.STORE_ID, INFO.DATE_STR)
      INCLUDE (INFO.SELLER_ID, INFO.CAR_ID, INFO.SHARE_PV, INFO.FLOW_PV, INFO.CALL_PV, INFO.APPOINT_PV)
      COMPRESSION='SNAPPY',DATA_BLOCK_ENCODING='DIFF'
  

      CREATE INDEX SHOP_DATA_BY_SALER_CAR_V2_INDEX1
      ON FLOW.SHOP_DATA_BY_SALER_CAR_V2 (INFO.CAR_ID, INFO.DATE_STR, INFO.SHARE_PV)
      INCLUDE (INFO.SELLER_ID, INFO.FLOW_PV, INFO.CALL_PV, INFO.APPOINT_PV)
      COMPRESSION='SNAPPY',DATA_BLOCK_ENCODING='DIFF'
  

  • 數據樣例的選擇：sql查詢時間範圍均為1個月，查詢條件由挑選出這1個月中按車商、銷售、車輛各個分組總條數在前300、300、300的數據按照模板隨機組合查詢。保證sql查詢都能命中數據，同時也排除每次都是量很大的數據。數據樣例見最後。測試表的數據量級在億行以上。

• 係統情況

  • ECS：4CPU8GB。
  • HBase節點信息：Master(4CPU8GB) Core(4CPU8GB) 數據盤都為雲盤。

• 壓測分別從10 ~ 100並發之前壓測，以10為累加單位進行壓測，壓測時間為10分鍾。目前我們業務場景每秒並發數在50 ~ 80左右，高峰期高於80。

  • 壓測的場景模擬線上的請求，查詢基本是都是單表比較複雜的聚合操作。
  • 壓測結果分別從TPS(每秒處理任務數)、RT(平均響應數據)兩個指標衡量。
  • 以下挑選了並發數在100的時候應用GC、HBase係統負載情況。
    • 應用GC情況 左邊為應用日誌 右邊為GC(對應列分別為S0 S1 E O M CCS YGC YGCT FGC FGCT GCT)，應用本身GC狀態良好。
    • HBase負載，**從HBase 兩台數據節點負載看得出壓測的時候已經完全將HBase負載壓到極限之上，所以不難得出如果在係統資源充足的情況下，並發數相同的情況下，TPS、RT遠遠比目前的結果要好**。

四、寫在最後

• 進過壓力測試，以及上線了一段時間，ApsaraDB HBase Phoenix能滿足我們的業務場景的使用。同時Aliyun HBase支持橫向擴展以及靠譜的運維能力，也為後麵支持更高的並發提供夯實的基礎。
• 結合我們業務場景，基本都是單表的複雜聚合操作，對IO消耗比較大，因此最近遷移了HBase，把雲盤換成了SSD盤。提高IO的能力。遷移工具 同時期待Aliyun HBase的數據遷移能更加完善。

• 數據樣例, ps:數據集經過特殊處理。
