riakdataportation

Build/Install

• Install golang on your machine, making sure you have go command on PATH
  • https://golang.org/dl/
• Run go get github.com/likemindnetworks/riakdataportation/portation
• That should be it

Usage

Note that flags/options (e.g. -a) must go before arguments (e.g. import)

Riak Data Portation Tool
Usage: portation <export|import> <riak host with port>
  -a string
    	app name
  -c int
    	number of connections (default 20)
  -d string
    	data version
  -i string
    	input file for import
  -o string
    	output folder for export result (default ".")
  -v	print version

To Export data out of the DB

• -a Required. name of the application, e.g. teamDental
• -o the folder where the output is written to, default to current direction
• set first argument after the flags/options to export
• set second argument after the flags/options to url to the riak protocol buffer port

Example:

portation \
  -a teamCS \
  -o . \
  export Riak-dev-ELB-749646943.us-east-1.elb.amazonaws.com:8087

This will write to a file named similar to teamCS.2016-03-10T16:41:56-05:00.bin. The format is:

<app name>@<data version>.<timestamp>.bin

To Import data into the DB

• -i the path to data file generated from exporting
• -a name of the application, e.g. teamDental, When importing, the app name can override to app name in the data file, this allows data from one app to be imported into another app. This requires caution and a confirmation will be asked
• set first argument after the flags/options to import
• set second argument after the flags/options to url to the riak protocol buffer port

Example:

portation \
  -a teamCS \
  -i ./teamCS.2016-03-10T16:41:56-05:00.bin \
  import Riak-dev-ELB-749646943.us-east-1.elb.amazonaws.com:8087

Data File Format

A request followed by its corresponding response. There are only two types request and response pairs:

• RpbGetReq, RpbGetResp
• DtFetchReq, DtFetchResp

|protocol header (5 bytes)|request protocol message|protocol header (5 bytes)|response protocol message|...
