Our most recent MariaDB Server release introduced some regressions starting with the 10.6 series, affecting 10.7 – 10.9 as well. This blog post is here to explain the problems in hopes that the impact is minimized. We are likely going to release a new version of MariaDB correcting these problems soon.
InnoDB Full Text Index on tables causes an assertion error (MDEV-29342)
There was a bug in the InnoDB Storage Engine where the full text index could go out of sync with the actual table data. This would happen when only one new row was inserted between the last InnoDB sync (which happens asynchronously) and a server shutdown.

SHOW ANALYZE
If you ever had to do query performance troubleshooting with MariaDB, you should be
familiar with MariaDB’s ANALYZE for statements feature. It does what EXPLAIN ANALYZE does in some other database systems: ANALYZE query runs the query and produces EXPLAIN output, amended with the data from the query execution:
FROM orders, customer
WHERE
customer.c_custkey = orders.o_custkey AND
customer.c_acctbal < 0 AND
orders.o_totalprice > 200*1000
