Teiid 8.1 CR1 发布了,基于 AS7 7.1.1-Final 发布,我们很高兴已经到了最终正式版的阶段了。

与 Beta1 版本比较,CR1 主要新特性包括:

  • TEIID-1598 转换器结果缓存 - translators can interact with the result set caching facility via a CacheDirective. See the Developer's Guide for more.
  • TEIID-2077 结果重用 - the engine will automatically detect if the same source query is used multiple times in a plan and reuse the result rather than issuing another query.
  • TEIID-2113 相关解析器的改进 - the parser will now accept the LATERAL keyword for defining a LATERAL join (previously we just used the TABLE keyword), unary negation is now supported e.g. -col1, the FOR keyword is optional for TEXTAGG, and the BNF documentation was dramatically improved.
  • TEIID-2036 依赖联合数组比较 - platforms supporting array comparisons can have multi-attribute dependent joins pushed down as array comparisons. Oracle, PG, and H2 translators are already marked as supporting array types.

同时该版本关闭了 100 issues ,正式版将很快发布。
