Readyset Package

This is a Kurtosis package. It allows you to run readyset cache which can improve performance for your SQL queries.

Run this package

Assuming that you have either postgres or mysql database running, replace UPSTREAM_DB_URL_CONNECTION_STRING with your connection string.

IMPORTANT: Do not use localhost or 127.0.0.1, instead use the IP Address as hostname for upstream_db_url.

The schema for creating a connection string is shown below. For more information regarding upstream_db_url , refer to the documentation here.

[postgresql|mysql]://<user>:<password>@<hostname>[:<port>]/<database>[?<extra_options>]

If you have Kurtosis installed, run:

kurtosis run github.com/kurtosis-tech/readyset-package '{"upstream_db_url": "UPSTREAM_DB_URL_CONNECTION_STRING"}'

To blow away the created enclave, run kurtosis clean -a.
