如何校准cassandra-stress图选项？

Question

我设法在集群之外运行了压力工具。我已经在cassa集群的bank关键字空间中准备好了基本的表bank_transactions。

bank.bank_transactions ( customerid文本，年份int，月份int，id timeuuid，金额int，卡片文本，状态文本，主键((customerid，年，月)，id) )；这是我的资料yaml文件：

table: bank_transactions

columnspec:
  - name: customerid
    size: uniform(5..10)
    population: uniform(1..10)
  - name: year
    size: fixed(4)
  - name: month
    size: fixed(2)
  - name: timeuuid
    cluster: uniform(20..40)
  - name: amount
    size: uniform(0..1000000)
  - name: text
    size: uniform(10..15)
  - name: status
    size: uniform(10..20)

insert:
    # How many partition to insert per batch
  partitions: fixed(2)
    # How many rows to update per partition
  select: fixed(1)/500
    # UNLOGGED or LOGGED batch for insert
  batchtype: UNLOGGED

queries:
   customer:
      cql: select *  from bank_transactions where customerid = ? and year = ? and month = ? and id = ?
      fields: multirow
#com.datastax.driver.core.exceptions.InvalidQueryException: 
#Partition key parts: year, month, id, customerid must be restricted as other parts are
   transactions:
      cql: select customerid, amount, card, status, id from bank_transactions where id = ? and customerid = ? and year = ? and month = ? 
      fields: samerow
   regularupdate:
      cql: update bank_transactions set amount = ? where customerid = ? and year = ? and month = ? and id = ?
      fields: samerow
#nestihalo se v casovem limitu, lze navysit pamet, casovy limit...      
#   updatewithlwt:
#      cql: update bank_transactions set amount = ? where customerid = ? and year = ? and month = ? and id = ? IF status = ?
#      fields: samerow

我的压力很大

./cassandra-stress user profile=./stress_transactions.yaml ops\(insert=3,customer=3,transactions=2,regularupdate=1\) \
n=10000 -node 172.16.20.104,172.16.20.105,172.16.20.106 -port native=9042 thrift=9160 jmx=7199 -graph file=./transactions.html

我希望在cassandra.apache站点上有一些类似于图形的东西

但结果真的很奇怪：

你能帮帮我吗，出什么事了？

另外，不要介意发行版本等等，它只是一个游乐场…

Answer 1

在另一个游戏时间之后，我设置了n=1000000 (没有其他更改)，结果要好得多。

希望能对某些人有所帮助;)
