I have several applications/microservices running on different application servers. 我在不同的应用程序服务器上运行了几个应用程序/微服务。 I want to persist some data in each of the applications for statistical/monitoring purposes. 我想在每个应用程序中保留一些数据，以进行统计/监视。 The data-format is very simple and there will probably only be a couple of tables in each database. 数据格式非常简单，每个数据库中可能只有几个表。 The performance has to be very fast with minimal overhead. 性能必须非常快且开销最少。

All the applications are running on Java EE 6 servers. 所有应用程序都在Java EE 6服务器上运行。 I'm therefore looking for a database that can be embedded on each application server with high performance and minimal configuration. 因此，我正在寻找一种可以以高性能和最少配置嵌入到每个应用程序服务器中的数据库。

Requirements: 要求：

Easy to embed on a Java EE application server 易于嵌入到Java EE应用程序服务器中
High performance and minimal overhead/footprint 高性能和最小的开销/占用空间
Minimal configuration and maintenance 最少的配置和维护
NoSQL is preferable 最好使用NoSQL
Clean Java API 干净的Java API
Possible to do SQL-like queries on each database and across the different databases 可以在每个数据库上以及跨不同数据库执行类似SQL的查询
Time-to-live on insert statements 插入语句的生存时间
Free 自由
Preferable Open Source 首选开源
