Step 1: Start RisingWave
The following options start RisingWave in the standalone mode. In this mode, data is stored in the file system and the metadata is stored in the embedded SQLite database. See RisingWave standalone mode for more details. For extensive testing or single-machine deployment, consider starting RisingWave via Docker Compose. For production environments, consider RisingWave Cloud, our fully managed service, or deployment on Kubernetes using the Operator or Helm Chart.Security reminderWhen using RisingWave in a production environment, make sure to change the default passwords for all superuser accounts (
root, postgres, and rwadmin). Leaving default passwords unchanged poses a serious security risk.Script installation
Open a terminal and run the followingcurl command.
Docker
Ensure Docker Desktop is installed and running in your environment.Homebrew
Ensure Homebrew is installed, and run the following commands:Step 2: Connect to RisingWave
Ensure you havepsql installed in your environment. To learn about how to install it, see Install psql without PostgreSQL.
Open a new terminal window and run:
Step 3: Insert some data
RisingWave supports both direct data insertion and streaming data ingestion from sources like message queues and database change streams. To keep things simple, we’ll demonstrate the approach of direct data insertion. Let’s create a table and insert some data. For instance, we can create a table namedcredit_card_transactions to store information about credit card usage.
Create the table
Insert five rows of data
Step 4: Analyze and query data
Next, we will detect potentially fraudulent behavior by identifying any card that spends more than $5000 within a one-minute window. To do this, we’ll use a materialized view. A materialized view in RisingWave is not a static snapshot or a one-time query. Instead, it’s a continuously maintained result that automatically stays up to date as new data arrives. You can think of it as a live dashboard behind a SQL query.Create a materialized view that detects high-spending cards in 1-minute windows
credit_card_transactions will automatically update fraud_alerts.
Query the current result
card_123 over the $5000 threshold.
Insert additional data to trigger fraud alert
Query the updated result
