众所周知,如果谈到云计算,扩展性也往往会出现在同一个句子中。但是绝少会提及数据库,更别说是MySQL数据库。一家波士顿的创业公司 ParElastic希望改变这一现状,它刚刚获得来自General Catalyst Partners( 前VMware CTO Steve Herrod的新“东家”)引导的570万美元的A轮融资。

ParElastic位于应用程序与底层数据库之间,而且无需复杂的分片操作就可以进行扩展操作,甚至可以把数据库迁移到一个更大的服务器上运行。公司创始人和首席执行官Ken Rugg告诉GigaOM的记者 Derrick Harris,从架构上讲,ParElastic数据库虚拟化引擎就像是一个并行的数据库系统,但是它在功能上是作为一个中间件,同时管理多个数据库实例,设计的初衷更偏向于操作而不是分析型的工作负载。 

数据库管理系统ParElastic:打破常规 扩展云端MySQL

因为ParElastic能够跨服务器之间智能地平衡数据库负载以及分配数据,所以在多租户的情况下,ParElastic也能很好的处理应用程序或者服务的请求,Rugg补充说道。

诚然,NoSQL数据库也在扩展性方面不断的努力,NewSQL则是致力赋予SQL数据库横向扩展的能力,甚至很多数据库已经作为云服务提供给了用户。然而,Rugg解释道,这些和ParElastic所从事的工作有很大的不同, 如果用户选择了NoSQL或者NewSQL,这就意味着需要部署一个全新的数据库,而且可能重写一些应用的代码。ParElastic的软件仅仅是是覆盖用户现有的云数据库。Rugg表示,在早期AWS的用户中,大约有一半都是使用标准版的MySQL版本,其余的则分布在Rackspace,Joyent和LiquidWeb等云服务供应商之中。

一些ParElastic的用户实际上是管理现有的SQL服务,像亚马逊的关系型数据库服务或者Google Cloud SQL,有人甚至用它来管理内部的数据库环境。Rugg指出,从技术上来讲,ParElastic是可以管理跨云平台的数据库,但这必然会导致服务的延迟,“我们并不建议这么做”。 Rugg认为,ParElastic技术的最大的受益者除了该公司之外还有AWS,这也是世界上使用最广泛的云平台。不过,当用户单一的数据库实例受到限制时,亚马逊一般的解决方案就是告知用户进行分片或者迁移到DynamoDB平台,“这点对那些想迁移到亚马逊云平台的用户来说,并不是很友好”Rugg说道。近一步而言,某些云服务供应商提供了比AWS更好的CPU,IO和网络性能(Rugg表示Rackspace在IO性能上就表现非常好),但是综合来看,AWS是一个很好的选择,尤其ParElastic帮助AWS弥补了自身的一些短板之后,就能以较低的成本提供更好的性能服务。

ParElastic现有的投资者还包括Point Judith Capital,  CommonAngels以及LaunchCapital,该轮融资之后,公司的风险资本总额达到870万美元。 (文/王鹏,审校/仲浩)

Adding Users to MySQL: The Complete TutorialAdding Users to MySQL: The Complete TutorialMay 12, 2025 am 12:14 AM

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
