This is a collection of scripts that I use to migrate code/plugins from ElasticSearch to OpenSearch.
There are two scripts that need to be copied in an user accessible path (ie. ~/bin/ )
- chcase: used to rename directories and files. I take it from http://www.primaledge.ca/chcase.html. It`s a old script from 2005, but I'm affectionated to it. Use chcase -e for example of usage
- to-os: a bash script that do the job simplify the conversation from Elasticsearch to OpenSearch namespaces/names.
The renaming is not 100% effective, but it does automatically a lot of the effort required in migrating a plugin.
The prerequisites are perl and bash, that are generally installed in every Linux system and MacOS.
The perl regex module must be installed on the system otherwise you should have a similar error:
Can't locate Regexp/Common.pm in @INC (you may need to install the Regexp::Common module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.30.0 /usr/local/share/perl/5.30.0 /usr/lib/x86_64-linux-gnu/perl5/5.30 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.30 /usr/share/perl/5.30 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at -e line 3.
BEGIN failed--compilation aborted at -e line 3.
On Ubuntu install it via:
sudo apt-get install -y libregexp-common-perl
On Unix/Macos:
cpan Regexp::Common
Convert it in a Scala script via ammonite or a Python one.
Due to license change of ElasticSearch to OSS license to a dangerous SSPL, it's not safe to manage my personal data assets in Elasticsearch anymore. In my home lab I built different tools around Elasticsearch:
- link tech collector crawling system to retrieve latest new about my technology passions (ie Scala, ElasticSearch, OpenSearch)
- huge collection of datasets for NLP processing and AI developing
- a collection of Italian recipes for my wife/grandma
- the catalog of my book/manga collections
- all my indexed source code
- ...
IMHO, the rationals are not AWS vs Elastic, but freedom vs lock-in. My position is more like Richard Stallman, but I am not a purist and I think the Apache 2 is a good licence.
