OSX How To: Uninstall native MySQL and install MariaDB via Homebrew

This is a short overview on how to completely remove any old mysql server installs in OSX and upgrade to MariaDB without conflicts. Things can get a bit weird when you have various old installs of MySQL server floating around, and utilizing homebrew to install and upgrade MariaDB as a drop in replacement for MySQL has worked well, especially if you're used to managing MySQL installs via yum in linux.

First: Backup Your Data!

Backup all of your current databases with mysqldump

This isn't a tutorial on backups, and there are many ways to do it. You should know how to backup your data anyway. For this example, we'll do a full backup of our InnoDB databases.

const eventFilterv5WithPagination = (contractAddress, erc20abi, _provider, numberOfResponses) => {
    // creating the interface of the ABI
    const iface = new ethers.utils.Interface(erc20abi.abi);
    
    // intialize array for the logs
    let logs = [];
    // get latest block number
    const latest = await provider.getBlockNumber();
    // intialize a counter for which block we're scraping starting at the most recent block
    let blockNumberIndex = latest;
