Here is a simple smart contract, with a bytes32 array called items in storage.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract SmartContract {

    bytes32[] public items;

    function addItem(bytes32 item) external {
        items.push(item);
    }

    function getAllItems() external view returns(bytes32[] memory) {
        return items;
    }

}

I wonder what's the actual maximum amount of data that an Ethereum node is willing to send back to a web client. Another way to ask this is, how large can the items array be before the getAllItems() function starts to fail.

1GB, 10GB, 100GB ?

Is that up to the node ? If so, what's the average configuration?

I believe knowing what the theoretical limit is would allow me to create a function that would retrieve only the right maximum amount of data.

I wasn't able to find a correct answer for previous questions on this topic.
