About InfluxDB

InfluxDB is an open-source time-series database designed to handle high-write and high-query workloads. It is part of the InfluxData platform, which includes other components like Telegraf (data collector), Chronograf (visualization and monitoring tool), and Kapacitor (real-time streaming and alerting engine).

Key features of InfluxDB include:

  1. Time-series data storage: InfluxDB is optimized for storing and querying time-stamped data, making it suitable for applications that generate a large volume of time-series data, such as monitoring systems, IoT devices, and financial data.

  2. High performance: InfluxDB is built to handle high write and query loads efficiently. It uses a log-structured storage engine, which enables fast writes and allows for efficient data compression and retrieval.

  3. SQL-like query language: InfluxDB uses a query language called InfluxQL, which is similar to SQL but tailored for time-series data. It provides functions and operators specific to time-series analysis and filtering.

  4. Retention policies and continuous queries: InfluxDB allows you to define retention policies to automatically expire or downsample data based on time. Continuous queries enable the creation of pre-computed aggregates or downsamples for faster query performance.

  5. Tagging and field support: InfluxDB uses a flexible data model that allows for the use of tags and fields. Tags are key-value pairs used for indexing and filtering data, while fields store the actual data values.

  6. High availability and clustering: InfluxDB Enterprise offers clustering capabilities, allowing you to set up a highly available and scalable InfluxDB cluster for increased reliability and performance.

  7. Integration with other tools: InfluxDB integrates with various data collection tools and frameworks, such as Telegraf, which enables the collection of data from a wide range of sources. It also supports integrations with Grafana, a popular visualization tool.

It's worth noting that InfluxDB has two major versions: InfluxDB 1.x and InfluxDB 2.x. The latter, also known as InfluxDB OSS 2.0, introduced significant architectural changes and a new query language called Flux. Flux offers more advanced functionality and flexibility compared to InfluxQL.

Using the MinIO API via curl

Using the MinIO API via curl is straightforward, as MinIO is compatible with Amazon S3 API, so most commands follow a similar syntax. Here’s a guide on how to use curl with the MinIO API for some common operations like uploading, downloading, and managing objects. Prerequisites Access Key and Secret Key : Obtain your MinIO Access Key and Secret Key. MinIO Endpoint : Know your MinIO server endpoint, e.g., http://localhost:9000 . Bucket : You may need an existing bucket name, or create a new one using the commands below. Authentication Header For requests to work with MinIO, you need to include authentication in the headers. MinIO uses AWS Signature Version 4 for signing requests. Common Examples 1. List Buckets To list all buckets in your MinIO account, use: curl -X GET \ - -url "http://localhost:9000/" \ - H "Authorization: AWS <AccessKey>:<Signature>" 2. Create a Bucket To create a new bucket, use: curl -X PUT \ - -url "htt...

Joining an additional control plane node to an existing Kubernetes cluster

Joining an additional control plane node to an existing Kubernetes cluster involves specific steps to ensure proper synchronization between the control plane components. Below is the detailed process: 1. Pre-Requisites Ensure the following on the new control plane node: Same Kubernetes Version : The new node must have the same Kubernetes version installed as the existing control plane. kubeadm version Kubeadm, Kubelet, and Kubectl Installed : Ensure these tools are installed and configured. Network Configuration : The new control plane must have network connectivity to the existing control plane nodes. 2. Retrieve the Join Command On an existing control plane node, generate the kubeadm join command with the --control-plane flag: kubeadm token create -- print -join-command You will get output similar to: kubeadm join <control-plane-endpoint> : 6443 --token <token> \ --discovery-token- ca -cert-hash sha256 : <hash> \ --control-plane 3. ...

CDPEvents in puppeteer

In Puppeteer , CDPEvents refers to events emitted by the Chrome DevTools Protocol (CDP) . Puppeteer leverages CDP to interact with and control a Chromium-based browser. CDP provides detailed, low-level access to browser internals, such as network traffic, console logs, page lifecycle events, and more. You can listen to these CDP events through Puppeteer’s API to monitor or intercept browser activity. How to Listen for CDP Events in Puppeteer Enable the Required CDP Domain: Some events require enabling a particular domain (e.g., 'Network' , 'Page' , 'Runtime' ). Use page._client() to Access the CDP Session: Although it’s a bit lower-level, Puppeteer allows access to DevTools through the page._client() API. Example: Listening for Network Requests This example demonstrates how to intercept and log network requests using CDP. const puppeteer = require( 'puppeteer' ); ( async () => { const browser = await puppeteer.launch({ headless...

kafka polling vs listen

In Kafka, polling and listening are two different approaches to consuming messages, and they correspond to different APIs or frameworks. 1. Kafka Polling Polling refers to the use of Kafka's native poll() method in the Kafka Consumer API . It requires the consumer application to actively request messages from Kafka. Key Characteristics: Active Consumption : The application explicitly calls poll() in a loop to fetch messages. Manual Commit : Developers can choose when to commit offsets, giving fine-grained control over processing and checkpointing. Use Case : Recommended for applications where control over message consumption, offset management, or threading is critical. Example (Java): Properties props = new Properties(); props . put (ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092" ); props . put (ConsumerConfig.GROUP_ID_CONFIG, "group1" ); props . put (ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest" ); props . ...

How to change java version on gradle of flutter

To change the Java version used by Gradle in a Flutter project, you need to modify the build.gradle files of your Flutter project. Here's how you can do that: Steps: Locate the build.gradle files: You will find two build.gradle files in your Flutter project: One at the root level: <project_root>/android/build.gradle Another inside the app module: <project_root>/android/app/build.gradle Update the Java version in android/build.gradle : In the root build.gradle file, ensure that the sourceCompatibility and targetCompatibility settings are set to the desired Java version. Open <project_root>/android/build.gradle Look for the compileOptions block (or create it if it's not present). Update the Java version like this: allprojects { repositories { google() mavenCentral() } } subprojects { afterEvaluate { project -> if ( project .hasProperty( "android" )) { android { ...

The pierce selector in Puppeteer

The pierce selector in Puppeteer is an experimental feature that allows you to query shadow DOM elements more easily. Traditional CSS selectors don't pierce through shadow roots because they encapsulate their content to prevent styles and scripts from leaking in or out. The pierce selector solves this by bypassing the shadow DOM boundary and directly selecting elements within shadow trees. How to Use the Pierce Selector in Puppeteer Here’s an example of how to use it effectively: const puppeteer = require ( 'puppeteer' ); ( async ( ) => { const browser = await puppeteer.launch({ headless : false }); const page = await browser.newPage(); // Navigate to a page with shadow DOM await page.goto( 'https://example.com' ); // Select an element inside a shadow DOM using the pierce selector const element = await page.$( 'pierce:#shadow-element-id' ); if (element) { console .log( 'Shadow element found!' ); awai...
