Introduction

For the web managerAPI, Web Manager, bookings engine, my environment and webservices we don't use database listeners. For this, we have a separate flow in place, because we require additional information (such as pre-calculated prices) in the Elasticsearch index.

We use Elasticsearch to store availability and prices. Elasticsearch is a search engine that provides fast searches and grouping of data (so-called aggregations).
The availability index consists of documents and each document represents a possible stay; it contains (among other fields) a resourceId, arrival date, duration, distribution channel, units, price, and possibly an offer code.
Only accommodation types meeting the following criteria will be indexed:

• Are released
• Have rentability
• Have prices

Index Modes

We have several index modes available which all have their requirements and benefits. Below you can find a matrix in which per index mode the requirements, benefits, and limitations are listed.

An overview of which customer uses which index mode can be found here: Index Modes.
