在1月12日举办的Greenplum开源有道智数未来技术研讨会上，Pivotal中国研发中心Greenplum 产品经理李阳向大家介绍了Greenplum 6.0 新特性。

Greenplum是Pivotal公司投入研发十多年，基于开源PostgreSQL数据库开发的一款Share-Nothing架构的分布式MPP数据库，具备高并发、高可用和高灵活等多种特性，可以对大任务、复杂任务进行快速高效计算，恰到好处地满足并行数据计算性能和海量数据管理的需求，目前在金融、电信、零售等领域有着广泛应用。

Greenplum 6在升级PostgreSQL内核至9.4版本的同时，增加了大量新特性，包括基于WAL日志的mirror同步、分布式死锁检测、复制表、在线扩容、磁盘限额、自动master切换、zStandard压缩、GP-GP集群间高效查询等，在此次演讲中分析介绍了这些新特性。

greenplum-db-6.2.1-rhel7-x86_64.rpm

greenplum-db-6.2.1-rhel7-x86_64.rpm Pivotal Greenplum 6.2 Release Notes This document contains pertinent release information about Pivotal Greenplum Database 6.2 releases. For previous versions of the release notes for Greenplum Database, go to Pivotal Greenplum Database Documentation. For information about Greenplum Database end of life, see Pivotal Greenplum Database end of life policy. Pivotal Greenplum 6 software is available for download from the Pivotal Greenplum page on Pivotal Network. Pivotal Greenplum 6 is based on the open source Greenplum Database project code. Important: Pivotal Support does not provide support for open source versions of Greenplum Database. Only Pivotal Greenplum Database is supported by Pivotal Support. Release 6.2.1 Release Date: 2019-12-12 Pivotal Greenplum 6.2.1 is a minor release that includes new features and resolves several issues. New Features Greenplum Database 6.2.1 includes these new features: Greenplum Database supports materialized views. Materialized views are similar to views. A materialized view enables you to save a frequently used or complex query, then access the query results in a SELECT statement as if they were a table. Materialized views persist the query results in a table-like form. Materialized view data cannot be directly updated. To refresh the materialized view data, use the REFRESH MATERIALIZED VIEW command. See Creating and Managing Materialized Views. Note: Known Issues and Limitations describes a limitation of materialized view support in Greenplum 6.2.1. The gpinitsystem utility supports the --ignore-warnings option. The option controls the value returned by gpinitsystem when warnings or an error occurs. If you specify this option, gpinitsystem returns 0 if warnings occurred during system initialization, and returns a non-zero value if a fatal error occurs. If this option is not specified, gpinitsystem returns 1 if initialization completes with warnings, and returns value of 2 or greater if a fatal error occurs. PXF version 5.10.0 is included, which introduces several new and changed features and bug fixes. See PXF Version 5.10.0 below. PXF Version 5.10.0 PXF 5.10.0 includes the following new and changed features: PXF has improved its performance when reading a large number of files from HDFS or an object store. PXF bundles newer tomcat and jackson libraries. The PXF JDBC Connector now supports pushdown of OR and NOT logical filter operators when specified in a JDBC named query or in an external table query filter condition. PXF supports writing Avro-format data to Hadoop and object stores. Refer to Reading and Writing HDFS Avro Data for more information about this feature. PXF is now certified with Hadoop 2.x and 3.1.x and Hive Server 2.x and 3.1, and bundles new and upgraded Hadoop libraries to support these versions. PXF supports Kerberos authentication to Hive Server 2.x and 3.1.x. PXF supports per-server user impersonation configuration. PXF supports concurrent access to multiple Kerberized Hadoop clusters. In previous releases of Greenplum Database, PXF supported accessing a single Hadoop cluster secured with Kerberos, and this Hadoop cluster must have been configured as the default PXF server. PXF introduces a new template file, pxf-site.xml, to specify the Kerberos and impersonation property settings for a Hadoop or JDBC server configuration. Refer to About Kerberos and User Impersonation Configuration (pxf-site.xml) for more information about this file. PXF now supports connecting to Hadoop with a configurable Hadoop user identity. PXF previously supported only proxy access to Hadoop via the gpadmin Greenplum user. PXF version 5.10.0 deprecates the following configuration properties. Note: These property settings continue to work. The PXF_USER_IMPERSONATION, PXF_PRINCIPAL, and PXF_KEYTAB settings in the pxf-env.sh file. You can use the pxf-site.xml file to configure Kerberos and impersonation settings for your new Hadoop server configurations. The pxf.impersonation.jdbc property setting in the jdbc-site.xml file. You can use the pxf.service.user.impersonation property to configure user impersonation for a new JDBC server configuration. Note: If you have previously configured a PXF JDBC server to access Kerberos-secured Hive, you must upgrade the server definition. See Upgrading PXF in Greenplum 6.x for more information. Changed Features Greenplum Database 6.2.1 includes these changed features: Greenplum Stream Server version 1.3.1 is included in the Greenplum distribution. Resolved Issues Pivotal Greenplum 6.2.1 is a minor release that resolves these issues: 29454 - gpstart During Greenplum Database start up, the gpstart utility did not report when a segment instance failed to start. The utility always displayed 0 skipped segment starts. This issue has been resolved. gpstart output was also enhanced to provide additional warnings and summary information about the number of skipped segments. For example: [WARNING]:-********

Greenplum 6针对OLTP的使用场景完成了多项优化，极大的改进了多并发情况下简单查询、删除和更新操作的性能。这些改进包括： 合并Postgres内核版本至9.4，这些合并在带来一系列新功能的同时，也提升了系统的整体性能。例如，引入fastpath等锁优化，可以减少多并发情况下的锁竞争开销。 提供全局死锁检测，从而支持针对同一张HEAP表的并发更新/删除操作。 优化全局事务，从而减少开始事...

一、基本概念 Greenplum是一个面向数据仓库应用的关系型数据库，因为有良好的体系结构，所以 在数据存储、高并发、高可用、线性扩展、反应速度、易用性和性价比等方面有非常 明显的优势。Greenplum是一种基于PostgreSQL的分布式数据库，其采用sharednothing架构，主机、操作系统、内存、存储都是自我控制的，不存在共享。 本质上讲Greenplum是一个关系型数据库集群，它实际上是由数个独立的数据库服务 组合成的逻辑数据库。与RAC不同，这种数据库集群采取的是MPP（Massively
