1.4.3 MySQL Stability
---------------------
This section addresses the questions, `_How stable is MySQL Server?_'
and, `_Can I depend on MySQL Server in this project?_' We will try to
clarify these issues and answer some important questions that concern
many potential users. The information in this section is based on data
gathered from the mailing lists, which are very active in identifying
problems as well as reporting types of use.
The original code stems back to the early 1980s. It provides a stable
code base, and the `ISAM' table format used by the original storage
engine remains backward-compatible. At TcX, the predecessor of MySQL
AB, MySQL code has worked in projects since mid-1996, without any
problems. When the MySQL Database Software initially was released to a
wider public, our new users quickly found some pieces of untested code.
Each new release since then has had fewer portability problems, even
though each new release has also had many new features.
Each release of the MySQL Server has been usable. Problems have
occurred only when users try code from the `gray zones.' Naturally, new
users don't know what the gray zones are; this section therefore
attempts to document those areas that are currently known. The
descriptions mostly deal with Versions 3.23 and later of MySQL Server.
All known and reported bugs are fixed in the latest version, with the
exception of those listed in the bugs section, which are
design-related. See bugs.
The MySQL Server design is multi-layered with independent modules.
Some of the newer modules are listed here with an indication of how
well-tested each of them is:
* Replication (Stable)
Large groups of servers using replication are in production use,
with good results. Work on enhanced replication features is
continuing.
* `InnoDB' tables (Stable)
The `InnoDB' transactional storage engine has been stable since
version 3.23.49. `InnoDB' is being used in large, heavy-load
production systems.
* `BDB' tables (Stable)
The `Berkeley DB' code is very stable, but we are still improving
the `BDB' transactional storage engine interface in MySQL Server.
* Full-text searches (Stable)
Full-text searching is widely used. Important feature enhancements
were added in MySQL 4.0 and 4.1.
* `MyODBC' 3.51 (Stable)
`MyODBC' 3.51 uses ODBC SDK 3.51 and is in wide production use.
Some issues brought up appear to be application-related and
independent of the ODBC driver or underlying database server.
