PdVega, a new library for pandas, Elastic Cloud Enterprise version 1.1.3, Google Analytics’ Audiences report, EverString’s Data platform, and more in today’s top stories around machine learning, blockchain, and data science news.

1. Introducing PdVega, a library for creating Interactive Vega-Lite Plots for Pandas

The PdVega library allows quick creation of interactive Vega-Lite plots from Pandas dataframes. Vega-Lite is a visualization specification that allows users to declaratively describe which data features should map to which visualization features using a well-defined JSON schema. PdVega uses an API that is nearly identical to Pandas’ built-in plotting API. It is designed for easy use within the Jupyter notebook. The resulting plots are beautiful and dynamic data visualizations with a minimum of boilerplate. More information is available at the official documentation.

2. Elastic Cloud Enterprise version 1.1.3 released

Elastic Cloud Enterprise (ECE) 1.1.3 has been released with an important bug fix to support Elasticsearch 6.1.x deployments. This new release adds support for Elasticsearch and Kibana version 6.1.3 by fixing a potential data loss bug when attempting a cluster configuration change (meaning any cluster configuration change, such as an upgrade or the addition of capacity). More bug fixes include:

  • For stack versions 6.1.0 and above, Kibana now navigates to the home page when there is no data.
  • Added a check that ensures the reallocation of clusters happens only after data is successfully migrated.
  • Added an internal configuration flag when starting ZooKeeper that corrects a failure during an ECE upgrade.

Other minor bug fixes and changes can be found in the release notes.
