What is this?
This is a GPU based database engine written to use vector based processing and high bandwidth of modern GPUs
CUDA (nvcc) + Nvidia GPU
Modern GPU Library (included as submodule)
How to build?
git clone –recursive https://github.com/antonmks/Alenka.git
Vector-based processingCUDA programming model allows a single operation to be applied to an entire set of data at once.
Smart compressionUltra fast compression and decompression on GPU.
Database operations on compressed data.
Column-based storageMinimizes disk I/O by only accessing the relevant data.
Data skippingBetter performance without indexes.
Fast LoadingGpu based CSV parser loads the data into database at very high speed.
How to use it ?
Create your data files :
Run scripts load_orders.sql, load_lineitem.sql and load_customer.sql to create your database files.
Run your queries from a command prompt or use Alenka JDBC driver from Technica Corporation
Step 1 – Filter data
OFI := FILTER orders BY o_orderdate < 19950315;
CF := FILTER customers BY c_mktsegment == "BUILDING";
