Replication in Drizzle is done by generating "messages" using the Google Protocol Buffers library. Via the keyword CONCURRENT it can operate these statements in parallel. Through support of the EXECUTE command Drizzle can operate dynamic multi-statement SQL. An enumerated type (enum) that supports current 10,000 types.Variable-length arrays (including text and composite types) up to 4 GB in total storage size.This action is done before parsing occurs.Ī wide variety of native data types are supported, including: ![]() All triggers for Drizzle currently must be written in C++.Īny query can be matched and rewritten dynamically that is sent to the server. The PrimeBase BLOB streaming system, which allows Drizzle to stream binary large objects (BLOBs) via HTTP, makes use of this system. ![]() Drizzle's query planner is capable of using multiple indexes, from multiple engines to satisfy complex queries, using temporary in-memory bitmap index operations.ĭatabase triggers in Drizzle are supported for DML, DDL, and a number of additional event-based operations in the server. Via this, Drizzle includes built-in support for B+ tree and hash indexes. Like MySQL, Drizzle supports concurrent multiple engines. Plugin points have been added to support replication, storage engines, query rewrite, table functions, user-defined functions, protocol adapters, and multiple query caches. Drizzle is an ACID-compliant relational database that supports transactions via an MVCC design. Via its plugin system it currently supports logging to files, syslog, and remote services such as RabbitMQ and Gearman. It supports PAM, LDAP, and HTTP AUTH for authentication via plugins it ships. Features such as the query cache and authentication system are now plugins to the database, which follow the general theme of "pluggable storage engines" that were introduced in MySQL 5.1. #Mysql free client download how to#Microsoft Windows is not supported at this time, mainly for lack of Autotools support, but there has been discussion of how to accomplish this in a sensible manner.ĭrizzle is a re-designed version of the MySQL v6.0 codebase and is designed around a central concept of having a microkernel architecture. #Mysql free client download mac os#It is being developed for modern Unix-like operating systems, including Linux, FreeBSD, Mac OS X, and Solaris – in general, any OS that conforms to POSIX and has a working implementation of the GNU Autotools. Platforms and interfaces ĭrizzle is written in the C++ programming language, and stores its string data in the UTF-8 format. ![]() The developers of the product describe it as a "smaller, slimmer and (hopefully) faster version of MySQL". ĭrizzle is targeted at the web-infrastructure and cloud computing markets. In July 2016 the maintainers concluded that the time had come for "winding things up officially" because "none of us have any time to dedicate to Drizzle anymore". īy late 2013 the project's active phase had come to an end. #Mysql free client download code#Drizzle has actively participated in the Google Summer of Code Project since 2010. The first GA version was released in March 2011. It was also announced that Drizzle had entered Beta. In October 2010, Drizzle had 13,478 total contributions, 96 total contributors, and 37 active contributors. Drizzle source code, along with instructions on compiling it, are available via the project's Launchpad website. Ongoing development was handled by a team of contributors that included staff members from Canonical Ltd., Google, Six Apart, Sun Microsystems, Rackspace, Data Differential, Blue Gecko, Intel, Percona, Hewlett-Packard, Red Hat, and others. #Mysql free client download drivers#Old Drizzle files are distributed under version 2 and 3 of the GNU General Public License (GPL) with portions, including the protocol drivers and replication messaging under the BSD license.Įarly work on the fork was done mid-2008 by Brian Aker. Like MySQL, Drizzle had a client/server architecture and uses SQL as its primary command language. Drizzle is a discontinued free software/ open-source relational database management system (DBMS) that was forked from the now-defunct 6.0 development branch of the MySQL DBMS. ![]()
