Berkeley DB开源文件数据库

Berkeley DB是一个开源的文件数据库，介于关系数据库与内存数据库之间，使用方式与内存数据库类似，它提供的是一系列直接访问数据库的函数，而不是像关系数据库那样需要网络通讯、SQL解析等步骤。

Berkeley DB 6.2.23 发布了 ，

本次发布的一些提升：

1. Added support for global message prefixes. [#20514]

2. Added Replication Manager write forwarding, which enables a client to perform simple put and delete operations by forwarding them to the master.  [#21049]

3. Improved the way we mark a password as consumed.  [#23876]

4. Added support for IPv6. [#23878]

5. Added support for Java 8. [#24220]

6. Added support for ARMv7 and above, and for ARM64. ARMv6 and below are no longer supported. [#24312]

7. Add a new SMP-optimized data model that is especially valuable for highly multithreaded applications. A sliced Berkeley DB instance contains a collection of related Berkeley DB environments, known as slices, each containing a disjoint subset of records. Transactional consistency is individually maintained within each slice, rather than across multiple slices. [#24343]

8. DB now supports the client-server architecture by providing a stand-alone server program and Java client driver APIs. The server program offers remote access to DB features. The client driver APIs provide building blocks for applications that communicate with a database server. Multiple client applications can communicate with a single server simultaneously. [#24360]

9. Enabled support of the SQLite user authentication extension. [#24365]

10. Added Visual Studio 2012 projects. [#24674]

11. Encryption and checksum can now be enabled with external files (formerly known as BLOBs).  Note that only the data stored in the database will be encrypted and checksum protected.  The data in the external files will not be encrypted or checksum protected. [#24849]

12. The BLOB files feature has been renamed external files to reduce confusion with the SQL BLOB datatype.  The BLOB related functions have been deprecated, and replaced with new function names; for example, ext_file_threshold has replaced blob_threshold, and blob_threshold is deprecated. See the Upgrading section of the documentation for more details. [#24850]
