Introduction

This Index mode uses the cashflowrules directly to calculate the prices.

Performance

Faster processing time of changes since no pricecache is required to pre-calculate prices and only night prices are stored.

Small index size because of efficient storage of the availability data.

Requirements

• Nightly rates

Functional

• Distribution channels with the same representation and rates will end up in the same documents, for each of these groups of distribution channels we need to calculate prices.
• For distribution channels having unique specials, prices need to be calculated separately.
• X=Y offers are not supported in this index mode.
• Implies on unit level are not supported.

Flow

Elasticsearch index process

• Re-indexes are running twice a day: in the early morning and early evening (concern time zone). These completely refresh the availability index.
• Updates are running every hour or every half an hour(this differs per customer). These updates process changes in prices, rentability, representations, releases, and reservability.
• Depending on how many changes need to be processed, this process can take several seconds (no or few changes) to 50 minutes (many changes that need a complete refresh of the index).

• Price, offer, rentability, representation, release, and reservability changes are picked up with every update/re-index process.

  		Changes available
  	worst-case	best-case	average-case
  Index frequency	60 minutes	30 minutes	45 minutes
  Indexing time	40 minutes	5 minutes	15 minutes
  total	100 minutes	35 minutes	60 minutes

Side notes

Fully-booked accommodation types

If an accommodation type gets fully booked for a certain period, the availability index will be updated immediately by removing that accommodation type for that period from the index.

Changes requiring a full re-index

The following changes require a complete re-index before they will be available online, therefore it can take up to 12 hours (time between two re-indexes before they will be available online).

• Changing an amenity
• Changing capacity
• Changing the number of bathrooms
• Changing the number of bedrooms
• Changing priority
• Updates in rating
• Adding new stayperiods
