Reference: CDM Performance Test Data

Background

The performance metrics provided in this document are for reference only. The performance at your site may be affected by factors such as the data source performance at the source or destination, network bandwidth, latency, and the data and service model. It is recommended that you test the speed with a small amount of data before migration.

Environment

  • A xlarge CDM cluster of the 2.9.1 200 version
  • A table which has 50 million rows and 100 columns, and three HDFS binary files which have 35.97 million rows and 100 columns, 66.67 million rows and 100 columns, and 100 million rows and 100 columns, respectively.
  • Number of concurrent extraction jobs for determining the maximum extraction/write rate: 1, 10, 20, 30, and 50

Data Source Extraction and Write Performance Test Data

Table 1 and Table 2 provide the data extraction and write performance, respectively.
