数据导入:

活跃会员：30天内有消费

沉睡会员：90天内有消费，30天内没有消费

这个需求的难点在于计算累计值。思路是 使用天进行聚合，得到每天的值，然后使用sum () over 窗口，得到累加值，对于每天的累积情况，这里需要使用拉链表的思想，即构造一个生效日期，这里使用lead() over 窗口函数，取到下一个日期，然后再用这个当日时间去卡，即可得到当日对应的累计值。

数据导入:

门店的消费情况可以从dwm_sell_o2o_order_i表中出，

注册、充值、消费这些数据可以从dwm_mem_member_behavior_day_i中出，

余额数据可以从dwd_mem_balance_online_i中出。

需要注意的是，这里有新增的指标还有累计的指标，为了方便计算，可以分开求解。

新增指标可以大部分从dwm_mem_member_behavior_day_i中出，因为 dwm_mem_member_behavior_day_i是会员粒度的表，记录了会员的各种行为。在计算会员指标的时候，很多需要count()来计算的指标，可以转化成sum（1），根据条件进行判断即可。

指标分为累计值和新增值，累计值可以取当周最后一天的数值、新增值可以进行聚合得到。 ​ 需要注意的是，这里计算的是一张周表，所以当考虑到数据的场景时，需要取到当周所有的数据进行聚合，以及取到当周最后一天进行取累加值。

思考: 当计算某一天对应这一周的指标, 如果获取这一周相关的数据呢?

Presto--分布式SQL查询引擎

Presto-简介

• 背景

  大数据分析类软件发展历程。

  • ==Apache Hadoop-MapReduce==

    • 优点：统一、通用、简单的编程模型，分而治之思想处理海量数据。

    • 缺点：java学习成本高、MR执行慢、内部过程繁琐

  • ==Apache Hive==

    • 优点：SQL on Hadoop。sql语言上手方便。学习成本低。

    • 缺点：底层默认还是MapReduce引擎、慢、延迟高

  • 各种SQL类计算引擎开始出现，主要追求的就是一个问题：==计算如何更快，延迟如何降低==。

    • ==Presto/trino==

    • Spark On Hive、Spark SQL

    • Flink

    • .......

  FaceBook维护的原始版本: presto, 也叫prestoDBPresto创始人团队离职后研发并维护的: PrestoSQL 因为版权更名为Trino已经给大家整理好了对应网址如下:FaceBook维护的, Presto的官网: https://prestodb.io/    创始人团队维护的, Trino的官网: https://trino.io/	Presto创始人团队维护的, 因为版权更名为Trino: http://github.com/trinodb/trino	
  相关文章如下:Presto在有赞的实践之路: https://cloud.tencent.com/developer/news/606849 Presto更名为-Trino: https://www.sohu.com/a/441836081_106784	

• 介绍

  Presto是一个开源的==分布式SQL查询引擎==，适用于==交互式查询==，数据量支持GB到PB字节。

  Presto的设计和编写完全是为了解决==Facebook==这样规模的商业数据仓库交互式分析和处理速度的问题。

  presto简介: 一条Presto查询可以将多个数据源进行合并，可以跨越整个组织进行分析;presto特点: Presto以分析师的需求作为目标，他们期望响应速度小于1秒到几分钟;

• 优缺点

  # 优点
  1）Presto与Hive对比，都能够处理PB级别的海量数据分析，但Presto是基于内存运算，减少没必要的硬盘IO，所以更快。2）能够连接多个数据源，跨数据源连表查，如从Hive查询大量网站访问记录，然后从Mysql中匹配出设备信息。3）部署也比Hive简单，因为Hive是基于HDFS的，需要先部署HDFS。# 缺点
  1）虽然能够处理PB级别的海量数据分析，但不是代表Presto把PB级别都放在内存中计算的。而是根据场景，如count，avg等聚合运算，是边读数据边计算，再清内存，再读数据再计算，这种耗的内存并不高。但是连表查，就可能产生大量的临时数据，因此速度会变慢，反而Hive此时会更擅长。2）为了达到实时查询，可能会想到用它直连MySql来操作查询，这效率并不会提升，瓶颈依然在MySql，此时还引入网络瓶颈，所以会比原本直接操作数据库要慢。

---

Presto-架构、相关术语

• 架构图

  Presto是一个运行在多台服务器上的分布式系统。 完整安装包括==一个coordinator和多个worker==。 由客户端提交查询，从Presto命令行CLI提交到coordinator; coordinator进行解析，分析并执行查询计划，然后分发处理队列到worker。

  

  整个presto是一个 M-S架构 (主从架构):coordinator: 主节点  作用: 负责接收客户端发送的SQL, 对SQL进行编译, 形成执行计划, 根据执行计划, 分发给各个从节点进行执行操作
  discovery service: 附属节点作用: 一般内嵌在主节点中, 主要负责维护从节点列表, 当从节点启动后, 都需要到 discovery 节点进行注册操作
  worker节点: 从节点作用: 负责接收coordinator传递过来任务, 对任务进行具体处理工作(读取数据, 处理数据, 将处理后结果数据返回给coordinator)

• ==Connector== 连接器

  1、Presto通过Connector连接器来连接访问不同数据源，例如Hive或mysql。连接器功能类似于数据库的驱动程序。允许Presto使用标准API与资源进行交互。2、Presto包含几个内置连接器：JMX连接器，可访问内置系统表的System连接器，Hive连接器和旨在提供TPC-H基准数据的TPCH连接器。许多第三方开发人员都贡献了连接器，因此Presto可以访问各种数据源中的数据，比如：ES、Kafka、MongoDB、Redis、Postgre、Druid、Cassandra等。

• ==Catalog== 连接目录: hive或者mysql等数据源

  1、Presto Catalog是数据源schema的上一级，并通过连接器访问数据源。2、例如，可以配置Hive Catalog以通过Hive Connector连接器提供对Hive信息的访问。3、在Presto中使用表时，标准表名始终是被支持的。
  例如，hive.test_data.test的标准表名将引用hive catalog中test_data schema中的test table。
  Catalog需要在Presto的配置文件中进行配置。
  

• ==schema== 库

  Schema是组织表的一种方式。Catalog和Schema共同定义了一组可以查询的表。当使用Presto访问Hive或关系数据库（例如MySQL）时，Schema会转换为目标数据库中的对应Schema(database)。= schema通俗理解就是我们所讲的database.
  = 想一下在hive中，下面这两个sql是否相等。
  show databases; -- presto不支持
  show schemas;

• ==table== 表

Presto--时间日期类型注意事项

• ==date_format==(timestamp, format) ==> varchar

  • 作用: 将指定的日期对象转换为字符串操作

• ==date_parse==(string, format) → timestamp

  • 作用: 用于将字符串的日期数据转换为日期对象

  select date_format( timestamp '2020-10-10 12:50:50' , '%Y/%m/%d %H:%i:%s');
  select date_format( date_parse('2020:10:10 12-50-50','%Y:%m:%d %H-%i-%s') ,'%Y/%m/%d %H:%i:%s');----
  注意: 参数一必须是日期对象所以如果传递的是字符串, 必须将先转换为日期对象:  方式一:  标识为日期对象, 但是格式必须为标准日期格式timestamp '2020-10-10 12:50:50'date '2020-10-10'方式二: 如果不标准，先用date_parse解析成为标准date_parse('2020-10-10 12:50:50','%Y-%m-%d %H:%i:%s')  扩展说明: 日期format格式说明年：%Y月：%m日：%d时：%H分：%i 秒：%s周几：%w(0..6)	

• ==date_add==(unit, value, timestamp) → [same as input]

  • 作用: 用于对日期数据进行 加 减 操作

• ==date_diff==(unit, timestamp1, timestamp2) → bigint

  • 作用: 用于比对两个日期之间差值

  select  date_add('hour',3,timestamp '2021-09-02 15:59:50');
  select  date_add('day',-1,timestamp '2021-09-02 15:59:50');
  select  date_add('month',-1,timestamp '2021-09-02 15:59:50');select date_diff('year',timestamp '2020-09-02 06:30:30',timestamp '2021-09-02 15:59:50')
  select date_diff('month',timestamp '2021-06-02 06:30:30',timestamp '2021-09-02 15:59:50')
  select date_diff('day',timestamp '2021-08-02 06:30:30',timestamp '2021-09-02 15:59:50')

Presto-常规优化

• 数据存储优化

  --1）合理设置分区与Hive类似，Presto会根据元信息读取分区数据，合理的分区能减少Presto数据读取量，提升查询性能。--2）使用列式存储Presto对ORC文件读取做了特定优化，因此在Hive中创建Presto使用的表时，建议采用ORC格式存储。相对于Parquet，Presto对ORC支持更好。Parquet和ORC一样都支持列式存储，但是Presto对ORC支持更好，而Impala对Parquet支持更好。在数仓设计时，要根据后续可能的查询引擎合理设置数据存储格式。--3）使用压缩数据压缩可以减少节点间数据传输对IO带宽压力，对于需要快速解压的，建议采用Snappy压缩。--4）预先排序对于已经排序的数据，在查询的数据过滤阶段，ORC格式支持跳过读取不必要的数据。比如对于经常需要过滤的字段可以预先排序。
  

• SQL优化

  • 列裁剪

  • 分区裁剪

  • group by优化

    • 按照数据量大小降序排列

  • order by使用limit

  • ==join时候大表放置在左边==

    ...

• 替换非ORC格式的Hive表

---

Presto-内存调优

• 内存管理机制--内存分类

  Presto管理的内存分为两大类：==user memory==和==system memory==

  • user memory用户内存

    跟用户数据相关的，比如读取用户输入数据会占据相应的内存，这种内存的占用量跟用户底层数据量大小是强相关的

  • system memory系统内存

    执行过程中衍生出的副产品，比如tablescan表扫描，write buffers写入缓冲区，跟查询输入的数据本身不强相关的内存。

• 内存管理机制--内存池

  ==内存池中来实现分配user memory和system memory==。

  内存池为常规内存池GENERAL_POOL、预留内存池RESERVED_POOL。

  

  1、GENERAL_POOL:在一般情况下，一个查询执行所需要的user/system内存都是从general pool中分配的，reserved pool在一般情况下是空闲不用的。2、RESERVED_POOL:大部分时间里是不参与计算的，但是当集群中某个Worker节点的general pool消耗殆尽之后，coordinator会选择集群中内存占用最多的查询，把这个查询分配到reserved pool，这样这个大查询自己可以继续执行，而腾出来的内存也使得其它的查询可以继续执行，从而避免整个系统阻塞。注意:
  reserved pool到底多大呢？这个是没有直接的配置可以设置的，他的大小上限就是集群允许的最大的查询的大小(query.total-max-memory-per-node)。reserved pool也有缺点，一个是在普通模式下这块内存会被浪费掉了，二是大查询可以用Hive来替代。因此也可以禁用掉reserved pool（experimental.reserved-pool-enabled设置为false），那系统内存耗尽的时候没有reserved pool怎么办呢？它有一个OOM Killer的机制，对于超出内存限制的大查询SQL将会被系统Kill掉，从而避免影响整个presto。

• 内存相关参数

  

  1、user memory用户内存参数
  query.max-memory-per-node:单个query操作在单个worker上user memory能用的最大值
  query.max-memory:单个query在整个集群中允许占用的最大user memory2、user+system总内存参数
  query.max-total-memory-per-node:单个query操作可在单个worker上使用的最大(user + system)内存
  query.max-total-memory:单个query在整个集群中允许占用的最大(user + system) memory当这些阈值被突破的时候，query会以insufficient memory（内存不足）的错误被终结。3、协助阻止机制
  在高内存压力下保持系统稳定。当general pool常规内存池已满时，操作会被置为blocked阻塞状态，直到通用池中的内存可用为止。此机制可防止激进的查询填满JVM堆并引起可靠性问题。4、其他参数
  memory.heap-headroom-per-node:这个内存是JVM堆中预留给第三方库的内存分配，presto无法跟踪统计，默认值是-Xmx * 0.35、结论
  GeneralPool = 服务器总内存 - ReservedPool - memory.heap-headroom-per-node - Linux系统内存常规内存池内存大小=服务器物理总内存-服务器linux操作系统内存-预留内存池大小-预留给第三方库内存

• 内存优化建议

  • 常见的报错解决

    1、Query exceeded per-node total memory limit of xx
    适当增加query.max-total-memory-per-node。2、Query exceeded distributed user memory limit of xx
    适当增加query.max-memory。3、Could not communicate with the remote task. The node may have crashed or be under too much load
    内存不够，导致节点crash，可以查看/var/log/message。

  • 建议参数设置

    1、query.max-memory-per-node和query.max-total-memory-per-node是query操作使用的主要内存配置，因此这两个配置可以适当加大。
    memory.heap-headroom-per-node是三方库的内存，默认值是JVM-Xmx * 0.3，可以手动改小一些。1) 各节点JVM内存推荐大小: 当前节点剩余内存*80%2) 对于heap-headroom-pre-node第三方库的内存配置: 建议jvm内存的%15左右3) 在配置的时候, 不要正正好好, 建议预留一点点, 以免出现问题数据量在35TB , presto节点数量大约在30台左右 (128GB内存 + 8核CPU)   注意：
    1、query.max-memory-per-node小于query.max-total-memory-per-node。
    2、query.max-memory小于query.max-total-memory。
    3、query.max-total-memory-per-node 与memory.heap-headroom-per-node 之和必须小于 jvm max memory，也就是jvm.config 中配置的-Xmx。

数据导入:

新会员：首次消费后30天内的；
老会员：首次消费后大于30天；需要统计每个门店每个月新会员、老会员、全部会员、非会员的数量、消费金额、消费单量。
注意：这里是一个月表，在判断新老会员的时候，按照当月最后一天为标准，往前推30天，30天内的为新会员。比如今天是5月28日，在计算5月份的数据时，4月29日——5月28日这30天的都是新会员。而在计算4月份数据时，因为4月份已经过去了，所以以4月30日为最后一天，4月1日——4月30日为4月份的新会员。

1）在计算月表时，需要取到当月最后一天，然后以最后一天为标准，取到前30天

selecta.trade_date,date_sub(a.trade_date, 30) as day30 -- 前30天,a.month_trade_date -- 对应的月一时间
from  dim.dwd_dim_date_f a
inner join(select max(dt) mdt from dws.dws_mem_store_member_statistics_day_i -- 取到最大的分区where dt>=date_sub('${inputdate}', dayofmonth('${inputdate}') - 1)and dt<=last_day('${inputdate}') ) b
on a.trade_date = b.mdt

2）新会员：30天内首次消费的会员

取新会员，可以使用首次消费表，取前30天到当月最大一天的会员即可。

因为在hive的where语句中不能使用子查询，所以这里使用join的方式解决

with dtt as (selecta.trade_date,date_sub(a.trade_date, 30) as day30 -- 前30天,a.month_trade_date -- 对应的月一时间from  dim.dwd_dim_date_f ainner join(select max(dt) mdt from dws.dws_mem_store_member_statistics_day_i -- 取到最大的分区where dt>=date_sub('${inputdate}', dayofmonth('${inputdate}') - 1)and dt<=last_day('${inputdate}') ) bon a.trade_date = b.mdt),
zt as (select s.zt_id from dwm.dwm_mem_first_buy_i s -- 取到最大分区与其前30天的数据cross join dttwhere s.dt >= dtt.day30 and s.dt <= dtt.trade_date)

数据导入:

复购是一个非常重要的指标，用来衡量客户的粘性。这个需求需要统计当天下单的用户，一日、二日到六日的复购情况，为了方便后续使用，这里不直接统计复购率，而是统计人数。所以，这个需求需要统计的指标为统计日期用户量、一日后用户量、二日后用户量、三日后用户量、四日后用户量、五日后用户量、六日后用户量。本需求类似于计算留存，也就是统计当天的用户，在1日、2日、3日。。。之后是否再次购买。

	使用dwm_mem_member_behavior_day_i表进行计算。因为需求中最多需要计算六日后的用户量，所以当天中的这些消费用户，需要6天之后，才能拿到所有的数据（1日后，2日后...6日后）。换个角度看，只有6天前的数据才会稳定，6天内的分区对应的数据每天都要进行更新，所以，每天要更新6个分区的数据。如果计算n天后的复购人数，其实就是用第一天的会员与第n天的会员进行关联，这里使用左关联，关联条件为会员id以及日期 能关联上的，即是复购的用户，然后再count()则可得到相应数值。
