Introduction Scrolling in Elasticsearch allows you retrieve a large number of documents, in steps or iterations, similar to pagination or a “cursor” in relational databases. In this article we’ll explore the Elasticsearch concept of scrolling, and how we can implement it in an application using the Python low-level client’s “helpers” library. Let’s go over how … Continued

Introduction In this tutorial, we will migrate some Elasticsearch NoSQL to Postgres with Python scripting. We’ll hold your hand each step of the way, beginning with the libraries you will need to install and reference in your Python code in order to open a Elasticsearch database and read from it, as well as the libraries … Continued
Introduction to the _mapping schema for Elasticsearch schema The _mapping of an index in Elasticsearch is the essentially the schema for the documents. It’s the layout of the index’s fields that sets up a blueprint for storing and organizing fields, and their respective data, when documents are indexed to the Elasticsearch index. Getting the mapping … Continued
Introduction to Elasticsearch and Python The Python low-level REST client for Elasticsearch maps closely to the Java API for the Elasticsearch client. This article demonstrates how you can use the client to create a _mapping schema for a document with an encoded bytes string, and then index an encoded dictionary. The article will demonstrate how … Continued
