FESTIval-v1.1.1

In this new release of FESTIval, we performed the following minor changes:

• Some improvements in the Makefile.
• Minor correction in the code (added the library float.h).
• Improvements of the compatibility between FESTIval and PostgreSQL/PostGIS (PostgreSQL >= 9.5 and PostGIS >= 2.2 and <= 2.5).
• Updates in the documentation of the FESTIval to better describe the installation guide.

FESTIval-v1.1

FESTIval is updated to support PostgreSQL 12 and PostGIS 2.5 (with compatibility to previous versions - PostgreSQL 9.5 and PostGIS 2.2) in this release. This means that this version is compatible with PostgreSQL >= 9.5 and PostGIS from version 2.2 to 2.5.

FESTIval allows users to:

• evaluate disk-based spatial indices (i.e., indices for magnetic disks): R-tree, R*-tree, and Hilbert R-tree.
• evaluate flash-aware spatial indices (i.e, indices for flash memories): FOR-tree, FAST-based indices, and eFIND-based indices.
• specify and execute user-defined workloads by using a unique environment.
• access an integrated data schema that stores index configurations and statistical data of executed workloads.
• use any spatial dataset in experiments. Default spatial datasets are also provided.
• reproduce executed workloads.

FESTIval manages a schema in the PostgreSQL called fds. This schema is automatically created by the FESTIval when the CREATE EXTENSION command is executed in a database. By using this schema, it is possible to collect and compare statistical data of different indices and analyze their performance results.

FESTIval-v1.0.1

Some minor corrections and improvements to the FESTIval.

FESTIval-v1.0

The first version of FESTIval is published in the MethodsX:

Carniel, A. C.; Ciferri, R. R.; Ciferri, C. D. A. FESTIval: A versatile framework for conducting experimental evaluations of spatial indices. MethodsX, vol. 7, 100695, 2020.
