MySQL 9.7, a Long-Term Support (LTS) release, incorporates a variety of potential features spanning across multiple technical domains. This article covers some of the primary features introduced and evaluates their practical utility within the MySQL database environment.

Following the End-of-Life (EOL) status of MySQL 8.0, this subsequent LTS release is designed to provide enhanced stability alongside significant architectural innovations.

Let’s discuss each of these features below with some examples and usage.

Flow-control monitoring in Group Replication

Flow control monitoring has been improved and provides more granularity by introducing the additional status variables listed below.

• Gr_flow_control_throttle_count : It denotes the number of transactions that have been throttled.
• Gr_flow_control_throttle_time_sum :It denotes the time in microseconds that transactions have been …

About a year ago, we discussed how MyDumper refactored its locking mechanisms to move away from old, rigid flags and transitioned towards more flexible, streamlined execution. Since then, the MyDumper community hasn’t stood still.

In recent releases, the locking architecture was further standardized under a single overarching option: --sync-thread-lock-mode. Along with this modernization came a powerful new safety feature designed to give you lock-free thread synchronization without risking silent inconsistency: SAFE_NO_LOCK (merged in PR #2031).

Let’s explore the new thread-synchronization landscape and break down when you should use each mode.

What is --sync-thread-lock-mode?

Previously, flags like …

The post InnoDB Flushing is simple – explained first appeared on Change Is Inevitable.

ducksdb-mysql-engine is an experimental build of MySQL 9.7 where a table you mark ENGINE=DuckDB answers analytical queries from DuckDB instead of InnoDB. Same server, same connection, no second copy of the data. On TPC-H at scale factor 10, InnoDB times out on 6 of the 22 queries and burns 1317 seconds on the 16 it finishes. The DuckDB tables run all 22 in about 15 seconds.

It’s an experiment, not production software. It patches mysqld and has rough edges, which we list at the end. Source is on GitHub under GPLv2:     https://github.com/EvgeniyPatlan/ducksdb-mysql-engine.

Why we made it

MySQL is great for transactions and slow at analytics. A wide GROUP BY over a few hundred million rows, or a six-way join, takes minutes on InnoDB. The usual fix is to copy the data into a column store and keep it in sync, so now …

TL;DR If you use MD5(), SHA1(), or SHA() in MySQL today, start planning the move to SHA2(). Beginning with MySQL 9.6, MD5(), SHA1(), and SHA() are no longer native built-in SQL functions in the server binary. They are available through the Legacy Hashing Component: That component should be treated as a stopgap solution. It gives […]
