Teiid 数据虚拟化系统
Teiid是一个数据虚拟化系统，让应用程序使用来自多个异构数据存储的数据。
Teiid由一堆工具，组件和创建和执行双向数据的服务所组成。通过抽象和联合、数据存取和集成的实时分布式数据源，无需进行复制或以其他方式移动数据系统的纪录。
简而言之：Teiid 可以让你用 JDBC + SQL 来访问企业的任何数据，并可对这些不同源的数据进行联合查询。
Teiid 9.3.3 已发布，该版本解决了 22 个 issues：
[TEIID-5021] - Latest openjdk does not include anon cipher suites
[TEIID-5028] - SystemFunctions should be loaded once
[TEIID-5017] - More aggressively use enhanced join sorted index to prevent buffering
[TEIID-5013] - Google Spreadsheet Data Sources with custom client_id and client_secret
[TEIID-4974] - Couchbase - TRANSLATE function is transalted as REPLACE
[TEIID-4983] - Couchbase tests rely on unpredictable order
[TEIID-5014] - Unable to use parameterized query with node pg module and Teiid/JBoss VDB
[TEIID-5019] - Makedep hint using @ syntax sometimes ignored
[TEIID-5020] - Join query results in NullPointerException
[TEIID-5029] - Regression with outer join optimization
[TEIID-5030] - Couchbase error in date/timestamp/time datatype pushdown
[TEIID-5031] - Couchbase issues in functions where result is different datatype than the argument
[TEIID-5033] - Couchbase substring function is 0-based
[TEIID-5035] - Couchbase INTERSECT doesn't return any values
[TEIID-5036] - Couchbase EXCEPT returns more values than expected
[TEIID-5037] - Couchbase UNION doesn't work correctly

[TEIID-5054] - autoFailover with a multi-batch result timing issue
[TEIID-5059] - CacheEntry memory leak due to issues with touch method
请注意，TEIID-5059 是一个特别重要的问题，因为它会导致某些情况下堆缓存条目的内存泄漏。
9.2.6 预计将在未来一两天内发布。
