Query engine synthesizer based on, our domain-specific language, VOILA

VOILA

Setup

VOILA can be installed using sandbox.sh. For instance, run N=<CORES> PREFIX=<DIR> sandbox.sh to install VOILA and its depedencies in

while compilation will use up to threads.

Direct

Queries can run directly using: /voila -s 1 -q q9 --default_blend "computation_type=vector(128),concurrent_fsms=1,prefetch=0"

This will run TPC-H Q9 on scale factor 1 using vectorized execution (with 128 tuple chunk size) with 5 repetitions and all available cores.

Alternatively, one can set a direct/old flavors:

For Hyper: /voila -s 1 -q q1 --flavor hyper

For Vectorwise: /voila -s 1 -q q1 --flavor vectorwise

Exploration

One can explore base flavors, i.e. one flavor per query, with: explorer -s 1 --base -q q9

One can explore per-pipeline flavors with: explorer -s 1 --pipeline -q q9

Experiments

• run_all.py runs all experiments.
• gen_tables.py generates plots/tables etc.
