HBase Object Mapper
Hi Guys, hope you all had a great weekend.
Recently, I had to do a lot of HBase data access and I needed a mapper,
but I didn't like any of the existing mappers (Gora, Kundera, etc.. ) maybe
I am mistaken. I just needed a light weight and easy to use mapper. So I
created one and put it on Github. It is very primitive at the moment, so if
any of you guys interested in doing some open source hacking, please give
me hand.

looking forward to hearing your feedback. Thanks

Cool, please try to run the tests, because I was getting strange issues related to versions and the mini cluster

I got some compilation error(s) after cloning your repo (

With the following change:

I was able to build your project.

Gora requires that you generate your classes through its compiler and you
can't touch these classes , do you really want to do that??
Kundera on the other hand is JPA which is a good idea, but I don't find it
natural for HBase, for ex: row key is very important in HBase, so you can't
just have a field that represents an id like you do for a relational
database, this why in my mapper I provide a function to generate the row
key. ex:
FluentEntityMapper.builder(Foo.class, "tableName")
.withRowKeyGenerator(new Function<Foo, String>() {
@Override
public String apply(Foo input) {
return input.name + (Long.MAX_VALUE -
System.currentTimeMillis()); // reversed timestamp
}
})

Nice,
thanks for Sharing Sleiman.
Can you do a quick pros and cons to compare Gora, Kundera and yours? Might
help so see which one fits best for other people usecases?
Thanks,
JM
