Big Data Migration: Import/Export

In this chapter

This chapter explains how to transfer big data between QueryIO server and other data sources.

What is Big Data Migration

Data migration is the process of transferring big data between storage types, formats, or computer systems. Data migration is usually performed programmatically to achieve an automated migration, freeing up human resources from tedious tasks. To achieve an effective data migration procedure, data on the old system is mapped to the new system providing a design for data extraction and data loading.

QueryIO provides data migration services from and to different data stores. It provides two services:

Currently QueryIO supports Amazon S3 cloud server and File Transfer Protocol(FTP), HDFS, POP/IMAP, HTTP/HTTPS, SSH, SFTP and also supports import from local system.


Data Migration Details

Currently QueryIO supports following data stores from which data can be imported:

To import a data from other source, click on Import button on Data Migration page.

Data Stores

Data Export

To transfer data from our system to other data store and enabling the two stores to share the same data.

Currently QueryIO supports following data stores to which data can be exported:

To export a data to other source, click on Export button on Data Migration page.
