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

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 2015-02-15 9:49 GMT-05:00 Sleiman Jneidi jneidi.slei...@gmail.com: Hi Guys, hope you all had a great weekend.

HBase Object Mapper

2015-02-15 Thread Sleiman Jneidi
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

I don't understand you. There is a single instance of servlet per application. Servlet.init method called once. Here you can instantiate HConnection and solve ANY concurrency problems. HConnection is tread-safe. Just don't close it and reuse. Then just use HConnection to get HTable. What problem

If sharing one HConnection for the whole application, when concurrency to access servlets increases to a threshold, whether or not it will influence the application performance? But if increasing the sharing HConnection number, the problem will be relieved?

Re: Re: Re: managing HConnection

2015-02-15 Thread Sleiman Jneidi
That's true, we can share the connection, but the problem is, HConnection implements Closeable, and hence its close method is public. If you share the same connection in your api, you always have to check if the current connection is closed before you return it to the client, check previous
