pg_siose_bench

A PostgreSQL extension with tools for benchmarking different SIOSE database configurations (pure relational, indexed, json, jsonb, xml, etc)

INSTALLATION

Requirements: PostgreSQL 9.5+, postgis extension

In directory where you downloaded pg_siose_bench run

make
sudo make install

SETUP

NEED TO START HERE!!! All other steps depend on this one Rename or drop columns, add indexes, comma separated text to arrays, etc

SELECT relational.setup_relational();

Now, use the create a JSONB document store

SELECT relational.jsonb_setup();

Build grids from geometries in the relational schema. You could replace 'relational.siose_polygons' by 'jsonb.docstore_jsonb' and get the same results. However, you could use a diferent boundary (e.g. administrative region, ROI, etc).

SELECT grids.build_regular_grids('grids.spain_boundary_100k', 'relational.siose_polygons');

Add logging capabilities

SELECT reports.setup_log_query_plans();

EXPERIMENTS

Now, you can use several testing functions to perform some experiments.

Run a complete relational experiment

SELECT relational.reclass_into_coniferous_density_groups();
SELECT relational.sum_area_of_coniferous_plantations();
SELECT relational.which_coniferous_patches();
SELECT relational.which_large_coniferous_patches();
SELECT relational.which_reforested_areas();
SELECT relational.which_scattered_urbanisation();

Run a complete jsonb experiment

SELECT jsonb.reclass_into_coniferous_density_groups();
SELECT jsonb.sum_area_of_coniferous_plantations();
SELECT jsonb.which_coniferous_patches();
SELECT jsonb.which_large_coniferous_patches();
SELECT jsonb.which_reforested_areas();
SELECT jsonb.which_scattered_urbanisation();
