Accumulator: A Go-based Data Accumulation Mechanism

Overview

Accumulator is a lightweight Go library designed to aggregate, manage, and process data items. Whether you're accumulating data from various sources, processing them at specific intervals, or simply managing a stream of data, this library provides the tools you need.

Features

• Flexible Storage: Choose from built-in storage options like in-memory storage or integrate with your custom storage mechanism.
• Customizable Processing: Define how data items are processed using your custom function.
• Configurable Interval: Set the interval at which accumulated data is processed.
• Scheduled Processing: Optionally start processing data at a specific time.

Installation

To install the package, simply run:

go get github.com/9ssi7/acc

    Insert1 --> Insert2[Insert Data 2];
    Insert2 --> Insert3[Insert Data 3];
    Insert3 --> Insert4[Insert Data 4];
    Insert4 --> Insert5[Insert Data 5];
    Insert5 --> IndexBroken[Index Broken];

Usage

Basic Setup

Here's a basic example demonstrating how to set up an accumulator:

package main

import (
	"fmt"
	"time"

	"github.com/9ssi7/acc"
)

func main() {
	config := acc.Config[int]{
		Processor: processFunction,
		// ... other configurations
	}

	accumulator := acc.New(config)
	// Start using the accumulator
}

func processFunction(data []int) {
	// Your logic to process data
	fmt.Println("Processing data:", data)
}

Advanced Configurations

Using StartTime Configuration

To start the accumulator processing at a specific time, you can use the StartTime configuration. Below is an example demonstrating how to set a start time:

func main() {
	config := acc.Config[int]{
		Processor: processFunction,
		StartTime: time.Date(2024, time.December, 31, 23, 59, 0, 0, time.UTC), // Processing will start on New Year's Eve at 23:59
		// ... other configurations
	}

	accumulator := acc.New(config)
	// Start using the accumulator
}

Using Interval Configuration

To configure the interval at which accumulated data is processed, you can set the Interval configuration. Below is an example demonstrating how to set an interval:

func main() {
	config := acc.Config[int]{
		Processor: processFunction,
		Interval:  30 * time.Second, // Data will be processed every 30 seconds
		// ... other configurations
	}

	accumulator := acc.New(config)
	// Start using the accumulator
}

Starting the Accumulator Asynchronously

To start the accumulator asynchronously using a goroutine, you can use the following approach:

func main() {
    config := acc.Config[int]{
        Processor: processFunction,
        Interval:  30 * time.Second, // Data will be processed every 30 seconds
        // ... other configurations
    }

    accumulator := acc.New(config)

    // Start the accumulator in a goroutine
    go func() {
        if err := accumulator.Start(); err != nil {
            fmt.Println("Error starting accumulator:", err)
        }
    }()

    // You can continue with other operations or wait for user input to exit
    // For example:
    // fmt.Println("Press Ctrl+C to exit...")
    // select {}
}

By starting the accumulator in a goroutine, it will run in the background, allowing the main program flow to continue without interruption.
