ary与 mirror端的数据不同步了，所以恢复的时候需要花比较 长的时间。对于Greenplum 3.X的版本，恢复时，需要 把好的节点上的所有数据都copy到坏的机器上。而 Greenplum4.0版本增加了功能，当备份节点坏的时 候，主节点可以把增量数据记下来，这样当备份节点的 主机恢复时，只需要恢复增量数据就可以了。 要让原先已offline的节点再加入集群中，需要重启集 群。 Greenplum中的高可用方案 对于Greenplum 3.X的版本，segment 的primary与 mirror之间是做的逻辑同步，mirror端的数据库实际上 也是可以读写的。而Greenplum4.0版本后，primary与 mirror实际上是物理同步，这时mirror一直处于恢复状 态，不能读也不能写。 高可用之Master Mirroring 对于Greenplum Maste GP的SQL支持程度 基本上绝大多数PostgreSQL支持的SQL，在 greenplum都支持，如常见的建表、建索引的ddl，以及 一般的dml语句。 Greenplum3.X不支持表空间。4.0提供了支持 tablespace功能。 不支持trigger。 建表语句多了distributed by 子名外， 其它的SQL语法 基本上都与PostgreSQL一样： CREATE TABLE

cast is typically used to describe this kind of cast. For example, consider this query: SELECT 2 + 4.0; The parser initially marks the constants as being of type integer and numeric, respectively. There and resolves the query as if it had been written as the following: SELECT CAST ( 2 AS numeric ) + 4.0; The catalogs also provide a cast from numeric to integer. If that cast were marked AS IMPLICIT, consistently support the latest database features and are fully compliant with Java™ SE 8 and JDBC 4.0 functionality.
