计算的功能也无能为力，就其因估计还是受到 mysql 在这方面限制。 3) 扩展性方面，Postgresql 比 mysql 也要出色许多，Postgres 天生就 是 为 扩 展 而 生 的， 你 可 以 在 PG 中 用 Python、C、Perl、TCL、 PLSQL 等等语言来扩展功能，在后续章节中，我将展现这种扩展 是如何的方便，另外，开发新的功能模块、新的数据类型、新的索 引类型等等非常方便，只要按照 API 接口开发，无需对 的 功 能，Postgresql 中 的 功 能 模 块 和 接 口 基 本 上 99% 都 可 以 在 Greenplum 上 使 用， 例 如 odbc、jdbc、oledb、perldbi、python psycopg2 等，所以 Greenplum 与第三方工具、BI 报表集成的时候非 常容易；对于 postgresql 的 contrib 中的一些常用模块 Greenplum 提 供了编 前文提到，得益于 Postgresql 的良好扩展性（这里是 extension，不 是 scalability），Greenplum 可以采用各种开发语言来扩展用户自定 义函数（UDF）（我个人是 Python 和 C 的 fans，后续章节与大家分享）。 这些自定义函数部署到 Greenplum 后可用充分享受到实例级别的并行 性能优势，我们强烈建议用户将库外的处理逻辑，部署到用 MPP 数 据库的
