This is the second episode of the Rust Compile Time series. Brian Anderson, one of Rust's original authors, talks about monomorphization, using the TiKV project as a case study.

TiDB 4.0 release greatly outperforms TiDB 3.0. Our TPC-C benchmark improved by about 50% and our TPC-H benchmark improved by about 100%.

TiDB 4.0 introduces TiDB Dashboard, which provides various built-in widgets in a graphical interface that let you easily diagnose, monitor, and manage your clusters in one place. Now you can troubleshoot TiDB clusters more easily.

With improvements in stability and functionality in TiDB 4.0, we finally remove the experimental label for pessimistic locking, making it a generally available feature. See how pessimistic locking behaves in TiDB.

TiDB 4.0 introduces TiCDC, an open-source feature that replicates TiDB's incremental changes to downstream platforms. It shows only millisecond replication latency for 100+ TB clusters.

This post describes how we implemented support for large transactions in TiDB 4.0.
