Feb 2015 Release

This release sees a shift from the use of RDD to SchemaRDD, allowing for SparkSQL to be applied in the tiling process (#114, #124). A new tile pipeline API and a library of pre-processing primitives have also been introduced, allowing for the creation of a chain of operations that can be applied to data prior to tiling (#132).

Note: Some minor modifications have been made to the tile properties used in the configuration files:

• oculus.binning.index.field.<order> replaces oculus.binning.xField and oculus.binning.yField
• oculus.binning.value.field replaces oculus.binning.valueField
• oculus.binning.index.type has been added

See tiling properties documention for a complete description.

June 2014 Release

v0.3.0

Bump aperture.js version to 1.0.7 final

Client-side Rendering

See check-in comments for detailed changes.

The biggest change from release 0.1.0 is the ability, on the server side, to fulfill tile requests in .json format (and the ability to convert .avro files to json), and the ability, on the client side, to request .json tiles, and infrastructure for displaying them, rendering them using Aperture.

Initial Baseline Version

This initial release of Aperture-Tiles only really supports server-rendered tile sets, but it should support them pretty fully.

The attached PDF is a good detailed description of the project.
