    Lee Roland 3 Techniques to Improve Postgres Response Times without Code Changes at Silicon Valley 2023
    Improve Performance via SQL Offload

    presented by Lee Roland

    In this session, we will discuss ways to offload SQL for low latency; all without code changes. We will discuss how database proxies (commercial and open-source) can intelligently cache, split and route queries for optimal Postgres performance and scale. During the presentation, it will be an interactive discussion with Q&A. Come join us.

    Lee Roland Improve Write-Master and Read Replica scale, safely without application changes at Postgres Conference 2020
    Read/Write split and Replication lag detection made easy with a database proxy

    presented by Lee Roland

    Horizontally scaling your SQL database involves separating the write-master from read-only servers. However, writing to one node and reading from another can result in inconsistent data due to synchronization delays.

    Database proxies intelligently route SQL queries to the best data source for even load distribution, while guaranteeing consistency.

    In this session, we will provide a hands...
