Subject [VOTE] Release Apache ShardingSphere (Incubating) 4.0.0
Date Mon, 06 Jan 2020 03:45:17 GMT
Hello all,

This is a call for vote to release Apache ShardingSphere (Incubating)
version 4.0.0.

The Apache ShardingSphere community has voted on and approved a proposal to
Apache ShardingSphere (Incubating) version 4.0.0.

We now kindly request the Incubator PMC members review and vote on this
incubator release.

ShardingSphere is an open-source ecosystem consisted of a set of
distributed database middleware solutions, including 2 independent
products, Sharding-JDBC & Sharding-Proxy.
They both provide functions of data sharding, distributed transaction and
database orchestration, applicable in a variety of situations such as Java
isomorphism, heterogeneous language.
Aiming at reasonably making full use of the computation and storage
capacity of the database in a distributed system, ShardingSphere defines
itself as a middleware, rather than a totally new type of database.
As the cornerstone of many enterprises, relational database still takes a
huge market share.
Therefore, at the current stage, we prefer to focus on its increment
instead of a total overturn.

Sharding-JDBC defines itself as a lightweight Java framework that provides
extra service at Java JDBC layer.
With the client end connecting directly to the database, it provides
service in the form of jar and requires no extra deployment and dependence.
It can be considered as an enhanced JDBC driver, which is fully compatible
with JDBC and all kinds of ORM frameworks.

* Applicable in any ORM framework based on Java, such as JPA, Hibernate,
Mybatis, Spring JDBC Template or direct use of JDBC.
* Based on any third-party database connection pool, such as DBCP, C3P0,
BoneCP, Druid, HikariCP.
* Support any kind of database that conforms to JDBC standard: MySQL,
Oracle, SQLServer and PostgreSQL for now.

Sharding-Proxy defines itself as a transparent database proxy, providing a
database server that encapsulates database binary protocol to support
heterogeneous languages.
Friendlier to DBA, the MySQL/PostgreSQL version provided now can use any
kind of terminal (such as MySQL Command Client, MySQL Workbench, Navicat
etc.) that is compatible of MySQL/PostgreSQL protocol to operate data.

* Totally transparent to applications, it can be used directly as MySQL and

* Applicable to any kind of terminal that is compatible with MySQL and
PostgreSQL protocol.
