1 | # Basic Redis Leaderboard Demo Java (Spring)
2 |
3 | A basic leaderboard application using Redis and Java/Spring. The application models public companies and their market capitalization.

16 | (See notes: How to run on Google Cloud)
17 |
18 |
19 | ## How to run on Google Cloud
20 |
21 |
22 | If you don't have redis yet, plug it in (https://spring-gcp.saturnism.me/app-dev/cloud-services/cache/memorystore-redis).
23 | After successful deployment, you need to manually enable the vpc connector as shown in the pictures:
24 |
25 |
26 | 1. Click on "Run on Google Cloud"
27 |
28 | 
29 |
30 | 2. Click "Edit and deploy new revision" button and choose "Variables and Secrets".
31 |
32 | 
33 |
34 | 3. Manage the traffic
35 |

41 |
42 |
43 | ## How it works?
44 |
45 |
46 | ## 1. How the data is stored:
47 |
48 | #### How the data is stored:
49 |
50 | - The AAPL's details - market cap of 2.6 triillions and USA origin - are stored in a hash like below:
51 | ```bash
52 | HSET "company:AAPL" symbol "AAPL" market_cap "2600000000000" country USA
53 | ```
54 |
55 | - The Ranks of AAPL of 2.6 trillions are stored in a ZSET.
56 |
57 | ```bash
58 | ZADD companyLeaderboard 2600000000000 company:AAPL
59 | ```
60 |
61 | #### How the data is accessed:
62 |
63 | - Top 10 companies:
64 |
65 | ```bash
66 | ZREVRANGE companyLeaderboard 0 9 WITHSCORES
67 | ```
68 |
69 | - All companies:
70 |
71 | ```bash
72 | ZREVRANGE companyLeaderboard 0 -1 WITHSCORES
73 | ```
74 |
75 | - Bottom 10 companies:
76 |
77 | ```bash
78 | ZRANGE companyLeaderboard 0 9 WITHSCORES
79 | ```
80 |
81 | - Between rank 10 and 15:
82 |
83 | ```bash
84 | ZREVRANGE companyLeaderboard 9 14 WITHSCORES
85 | ```
86 |
87 | - Show ranks of AAPL, FB and TSLA:
88 |
89 | ```bash
90 | ZREVRANGE companyLeaderBoard company:AAPL company:FB company:TSLA
91 | ```
92 |
93 | - Adding 1 billion to market cap of FB company:
94 |
95 | ```bash
96 | ZINCRBY companyLeaderBoard 1000000000 "company:FB"
97 | ```
98 |
99 | - Reducing 1 billion of market cap of FB company:
100 |
101 | ```bash
102 | ZINCRBY companyLeaderBoard -1000000000 "company:FB"
103 | ```
104 |
105 | - Companies between 500 billion and 1 trillion:
106 |
107 | ```bash
108 | ZCOUNT companyLeaderBoard 500000000000 1000000000000
109 | ```
110 |
111 | - Companies over a Trillion:
112 |
113 | ```bash
114 | ZCOUNT companyLeaderBoard 1000000000000 +inf
115 | ```
116 |
117 |
118 | ## How to run it locally?
119 |
120 | #### Open the files server/.env.example to see the available environment variables. You may set these variables when you start the application.
121 | - REDIS_URL: Redis server url
122 | - REDIS_HOST: Redis server host
123 | - REDIS_PORT: Redis server port
124 | - REDIS_PASSWORD: Redis server password
125 |
126 | #### Run backend
127 |
128 | 1. Install gradle (Use Gradle 6.3 or later) (on mac: https://gradle.org/install/)
129 |
130 | 2. Install JDK (use 8 or later version) (on mac: https://docs.oracle.com/javase/10/install/installation-jdk-and-jre-macos.htm)
131 |
132 | 3. Set any relevant environment variables (if not connecting to Redis on localhost:6379). For example:
133 |
134 | ``` sh
135 | $ REDIS_PORT=6379
136 | ```
137 |
138 | 3. From the root directory of the project, run the following commands:
139 | ``` sh
140 | cd server
141 | ./gradlew build
142 | ./gradlew run
143 | ```
144 |
145 | 4. Point your browser to `localhost:5000`.
