hamsterdb 2.1.7 released under Apache Public License!

[Christoph Rupp]

Hi,

I just released hamsterdb 2.1.7. It has a few bug fixes and a few performance improvements. Also, Transactions can now be used without the journal (in case you do not mind losing data if there’s a crash).

But the biggest change is not in code, it’s in the license: hamsterdb is no longer GPL, but released under APL (Apache Public License) 2.0. Unlike the GPL, the Apache license allows free use of hamsterdb in closed source applications.

My motivation for this change is that i see the GPL as a major obstacle for higher adoption. The GPL blocks the use of hamsterdb in too many open source projects. I want to improve adoption, therefore i decided to change the license.

In parallel i am working on a new commercial sibling of hamsterdb (called hamsterdb pro). It will offer additional features like compression, encryption, bulk updates, maybe even concurrency etc.

Encryption is typically used to comply with certain legal regulations (i.e. HIPAA), or to protect intellectual property. Both cases are not typical for open source projects, therefore i decided to remove the AES encryption from the publicly available APL version of hamsterdb and move it to the closed source commercial version instead. This is the only feature that was removed.

I hope i can release the first version of hamsterdb pro in 4 – 8 weeks.

hamsterdb 2.1.7 can be downloaded here: http://hamsterdb.com/download.

Best regards
Christoph

Dear Christoph Rupp

Grat for new website.

Remark

I see your Pro price. The nosql market is very big, 2000e price is very high, for this functions.

Hi Joe,

thanks for the feedback.

The new price is not much different from the old one, which was 450 € per developer seat. Customers on average bought 1 to 7 licenses.

The current feature set is just the beginning. In the pipeline are bulk updates, prefix compression, bitmap compression and a few other exclusive features for hamsterdb pro.

From my own perspective: looking at what i have invested (around 10 years of work) and the expenses i have, mainly for hardware (i need a new high-end machine with several commercial licenses for developer tools, new SSD, have to replace 2 HDDs which stopped working due to the extensive test cycles) - i think the price is justified.

Best regards
Christoph
