About
I am a C++/C software developer with a PhD in experimental physics. Having worked across a wide range of modern IT realms including embedded systems, SDKs, server backends, IoT, and GUIs for desktop as well as for embedded systems, I am currently focused on PostgreSQL development. My specific engineering focus within PG lies in the transaction system (especially in the upcoming 64-bit XID), heap layout, and highly efficient data compression, particularly differential compression methods.

Custom development of DFOR and its usage for PostgreSQL
presented by Evgeny Voropaev
The Delta Frame of Reference algorithm (DFOR) is a widely used solution for the lossless compression of integer sequences. DFOR, which is classified as differential compression method, provides a high compression ratio even for short data sequences, where statistical and dictionary-based compression methods can be ineffective. While nowadays the plenty of DFOR implementations are available...
