Products

  1. Launch redis-cli

  2. Show number of documents in RediSearch index:

    FT.INFO products

  3. Run simple keyword search:

    FT.SEARCH products chambly

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

  4. Run prefix search:

    FT.SEARCH products chamb*

  5. Open http://localhost

  6. Enter a simple keyword search, e.g. chambly. Note highlighted matches.

  7. Expand the filter panel by clicking on the filter button:

    filter list 24px

  8. Enter some characters in the Brewery field to retrieve suggestions from RediSearch (e.g. Unib)

  9. Click the Submit button

  10. Refine the search by adding a constraint on the alcohol content (ABV field):

    @abv:[7 9]

  11. Change the sort-by field to ABV and click Submit

Availability

  1. Click Availability on one of the search results. This takes you to the availability map for that product.

  2. The map shows stores near you where the selected product is currently available.

  3. Stores in green have more than 20 in stock, amber: 10 to 20, red: less than 10

Inventory

  1. Click on a store and then on the link that pops up

  2. This takes you to the real-time inventory for that store

  3. 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

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
