It’s always good to hear about NoSQL projects I’ve missed from the first versions of MyNoSQL. Now it is the case of ☞ GT.M, but thanks to Rob Tweed, starting today, MyNoSQL will also track GT.M and M/DB.
In case you, like me, are wondering what GT.M is, a good start would be the presentation ☞ “GT.M: A Tried and Tested Open-Source NoSQL Database”, from which I have found that GT.M, like kdb+ about which I’ve learned lately, has been in production for quite a long time (1986!).
The presentation is also introducing ☞ M/DB which is an open source emulation of Amazon SimpleDB that was built on top of GT.M
According to Rob:
It’s in fact a good example of something that has been discussed in the last couple of days in the NoSQL Google Group: namely where a schemaless key/value database (in this case GT.M) can be used as the raw pallette on which another database view (in this case the SimpleDB APIs and database behaviour) can be modelled.
It turns out that the SimpleDB behaviour can be very simply modelled on top of GT.M: in fact the first version from concept to production roll-out just took me a week: it was that close a fit!
If you look at ☞ GT.M for the Python Programmer doc (page 14) you’ll see a section “M/DB: GT.M in Action” that will perhaps provide some more insight on the connection between the two.
Update: It looks like Google has some problems returning good results for searches on GT.M and M/DB.
