BigData & Web3. What does Task Manager memory consist of in Apache Flink? Task Manager, the cluster's main combat unit, uses the memory allocated to it to store various data segments. Some of the memory is required to service the framework core (quite small), and some are used to service network buffers, with the help of which Task Manager communicates with its colleagues and the “leader” in the person of Job Manager (Netty is used for this). But the main question remains open — where to store the state? Let’s take a look at how Task Manager uses the memory allocated to it... ...

🤔 𝐃𝐨 𝐲𝐨𝐮 𝐡𝐚𝐯𝐞 𝐭𝐨 𝐫𝐞𝐥𝐲 𝐨𝐧 𝐉𝐒𝐎𝐍-𝐑𝐏𝐂 𝐟𝐨𝐫 𝐲𝐨𝐮𝐫 𝐄𝐭𝐡𝐞𝐫𝐞𝐮𝐦 𝐢𝐧𝐝𝐞𝐱𝐞𝐫? 𝐌𝐚𝐲𝐛𝐞 𝐧𝐨𝐭. Come to our workshop at EthCC and discover a faster, more efficient approach using P2P protocols! 👇🏼 🌐 𝐓𝐡𝐞 𝐄𝐭𝐡𝐞𝐫𝐞𝐮𝐦 𝐧𝐞𝐭𝐰𝐨𝐫𝐤 Ethereum operates on a peer-to-peer network with thousands of nodes that must communicate using standardized protocols. This includes broadcasting information (gossiping) and direct communication between nodes, which must follow specific rules for security and accuracy. The two main components, execution clients and consensus clients, work together to verify the network's state and to ensure the network’s smooth operation. Accessing blockchain data is a fundamental part of every web3 project. Traditionally, we've relied on JSON-RPC to interact with Ethereum nodes, sending requests and receiving data in a standardized format. But is this approach the most efficient? The answer might surprise you. 🙀 😞 𝐓𝐡𝐞 𝐥𝐢𝐦𝐢𝐭𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐉𝐒𝐎𝐍-𝐑𝐏𝐂 JSON-RPC is a common method for Ethereum developers to query blockchain data and send transactions. However, this approach introduces several challenges: 𝐒𝐩𝐞𝐞𝐝: JSON-RPC can sometimes be slow, especially when dealing with large volumes of data requests. 𝐑𝐞𝐥𝐢𝐚𝐛𝐢𝐥𝐢𝐭𝐲: using third-party services can lead to potential downtimes, affecting your application's performance. 𝐒𝐜𝐚𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲: handling numerous requests can be difficult and may require significant resources. ✅ 𝐀 𝐟𝐚𝐬𝐭𝐞𝐫, 𝐦𝐨𝐫𝐞 𝐫𝐞𝐥𝐢𝐚𝐛𝐥𝐞 𝐚𝐩𝐩𝐫𝐨𝐚𝐜𝐡: 𝐝𝐞𝐯𝐏𝟐𝐏 By leveraging Ethereum's devP2P protocols, you can achieve faster and more straightforward access to blockchain data. devP2P enables direct node-to-node communication, allowing you to bypass the JSON-RPC method that requires extensive infrastructure and resources to sync a node before querying data and to improve data retrieval speeds. But how? 👇🏼 👩🏽💻 𝐉𝐨𝐢𝐧 𝐨𝐮𝐫 𝐰𝐨𝐫𝐤𝐬𝐡𝐨𝐩: 𝐈𝐧𝐝𝐞𝐱𝐢𝐧𝐠 𝐄𝐭𝐡𝐞𝐫𝐞𝐮𝐦 𝐝𝐚𝐭𝐚 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐏𝟐𝐏 𝐩𝐫𝐨𝐭𝐨𝐜𝐨𝐥𝐬 In our upcoming hands-on workshop, you will learn how to leverage a minimalist and efficient Rust script, written by the software engineer Lola Rigaut-Luczak 🙌🏼, to call Ethereum blocks. We'll explore the technical details, including the RLPx transport protocol and the wire protocol which establish the foundations of communication between the Ethereum nodes .

As many scam contracts are non-verified, this check adds 𝗮𝗻 𝗲𝘀𝘀𝗲𝗻𝘁𝗶𝗮𝗹 𝗹𝗮𝘆𝗲𝗿 𝗼𝗳 𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 for dApps by verifying contracts before any interactions. 🌐 𝗧𝗿𝘆 𝗶𝘁 𝗼𝘂𝘁 👀 Use the DAPP: https://lnkd.in/eQAzBtMU Watch the demo: https://lnkd.in/eAqaBQG7 Github repo: https://lnkd.in/eMxMbK9q 🔗 Ensure that you are on the 𝗕𝗮𝘀𝗲 𝗦𝗲𝗽𝗼𝗹𝗶𝗮 network and have some Sepolia testnet tokens 💰, as each request costs 0.002 ETH (Sepolia) because Chainlink consumes LINK tokens for each request. ⌨️ And then just input the blockchain address of the smart contract that you want to check for verification into the prompt. ⏱️ In under a minute, 𝗖𝗵𝗮𝗶𝗻𝗹𝗶𝗻𝗸 𝗼𝗿𝗮𝗰𝗹𝗲𝘀 will communicate with 𝗕𝗮𝘀𝗲𝘀𝗰𝗮𝗻 and 𝗴𝗶𝘃𝗲 𝘆𝗼𝘂 a clear 𝘆𝗲𝘀 ✅ or 𝗻𝗼 ❌ 𝗮𝗻𝘀𝘄𝗲𝗿 about the contract's verification status. That's it! 😊 🚀 𝗡𝗲𝘅𝘁 𝗺𝗶𝗹𝗲𝘀𝘁𝗼𝗻𝗲 ? 🛠️ I’m working on developing a token or dApp that leverages this platform to analyze contract source code using 𝗔𝗜 and 𝗖𝗵𝗮𝗶𝗻𝗹𝗶𝗻𝗸 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝘀 for deeper insights. This will pose 𝗰𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲𝘀, especially given the complexity of contracts and AI's current limitations—but it’s a vital next step. 🌟 𝗧𝗵𝗶𝘀 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗵𝗶𝗴𝗵𝗹𝗶𝗴𝗵𝘁𝘀 𝗺𝘆 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝘄𝗶𝘁𝗵 𝗖𝗵𝗮𝗶𝗻𝗹𝗶𝗻𝗸 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝘀 𝗮𝗻𝗱 𝗼𝗽𝗲𝗻-𝘀𝗼𝘂𝗿𝗰𝗲 𝘁𝗼𝗼𝗹𝘀 𝗹𝗶𝗸𝗲 𝗦𝗰𝗮𝗳𝗳𝗼𝗹𝗱-𝗘𝗧𝗛-𝟮 𝗮𝗻𝗱 𝗞𝗿𝗲𝗱𝗲𝘂𝗺 𝗢𝗻𝗖𝗵𝗮𝗶𝗻𝗔𝗜 𝗲𝘅𝘁𝗲𝗻𝘀𝗶𝗼𝗻.
