sfDB5

A NoSQL Schemaless Relational Key-Structure Store

---

Have a look at the transcribed talk.

---

sfDB5 has three main inspirations:

• Inspiration I: Data Dependent Queries

  Solve recursion. In other words, instead of you recursing client-side and fetching data over and over again, you can just send the server a path string (similar to C's memory access syntax) and it'll do the recursion within the cluster. This is not only faster but is also (IMHO) easier to do.

• Inspiration II: Ease of Use

  Three of the top NoSQL databases today aren't as easy to use as a database should be. One isn't exactly trivial to administer, another requires you to learn a query language (isn't that part of what we wanted to escape with NoSQL?), and the final one requires you to do manual parsing.

  sfDB5 should have everything necessary in the box. Cluster administration is just adding and removing servers - sfDB5 will take care of the rest. There's no fancy query language, just simple path strings and standard functions. Parsing isn't a thing either. sfDB5 has its own efficient internal representation, but it'll just spit out a string, blob, integer or float when you ask it for data.

• Inspiration III: Atomic Operations

  Serverside atomic operations like basic arithmetic, bitwise, and shift operations are quite useful, especially in synchronization. While all sfDB5 operations are atomic, these additional functions can perform as basic synchronization primitives, especially seeing as that sfDB5 does not support external locking.

Dependencies

You will need the following:

• a Linux or OSX box (after networking is implemented, only Linux will work)
• GNU coreutils >= 8.9
• one of the following compilers which support GNU C:
  • gcc >= 4.8.0 (preferable)
  • clang >= 3.5.0
• a working copy of git >= 1.8.5
• GNU make >= 3.8
• premake4

Building

Here's how you go about it; please ensure that your output looks somewhat similar to the example output listed below (your results may be slightly different, depending on various factors):
