Demo Steps

Products

Launch redis-cli

Show number of documents inRedis Searchindex:

FT.INFO products

Run simple keyword search:

FT.SEARCH products chambly

TIP: name, description, breweryName are phonetic text fields so you will notice results containing words that sound similar.

Run prefix search:

`FT.SEARCH products chamb*`

• Open http://localhost[]
• Enter a simple keyword search, e.g. chambly. Note highlighted matches.
• Expand the filter panel by clicking on the filter button (image:https://pic.onlinewebfonts.com/svg/img_3152.png[width=24])
• Enter some characters in the Brewery field to retrieve suggestions fromRedis Search(e.g. Unib)
• Click the Submit button
• Refine the search by adding a constraint on the alcohol content (ABV field):

`@abv:[7 9]`

• Change the sort-by field to ABV and click Submit

Availability

Click Availability on one of the search results. This takes you to the availability map for that product. . The map shows stores near you where the selected product is currently available. . Stores in green have more than 20 in stock, amber: 10 to 20, red: less than 10

Inventory

• Click on a store and then on the link that pops up
• This takes you to the real-time inventory for that store
• The Available to Promise field is updated in real-time based on current difference between supply (On Hand) and demand (Reserved + Allocated + Virtual Hold).

Configuration

The app server is built with Spring Boot which can be configured different ways: Spring Boot Externalized Configuration

Depending on the way you're running the demo you can either:

• create a application.properties file based on the one that ships with Brewdis
• specify JVM arguments like this:

java -jar brewdis.jar --spring.redis.host=localhost --spring.redis.port=6379 ...

• use environment variables:

export spring.redis.host=localhost
export spring.redis.port=8080
export ...
java -jar brewdis.jar

Here are the most common configuration options for this demo:

• spring.redis.host: Redis database hostname (default: localhost)
• spring.redis.port: Redis database port (default: 6379)
• stomp.host: Websocket server hostname (default: localhost)
• stomp.port: Websocket server port (default: 8080)
• stomp.protocol: Websocket protocol (default: ws). Use wss for secure websockets
• inventory.generator.rate: duration in millis the generator should sleep between inventory updates (default: 100)
• availability-radius: radius to find in-store availability (default: 25 mi)
