问题 I'm having performance issues when querying ~12,000 user documents, indexed by 1 column, (companyId), no other filter. The whole collection only has ~27000.

问题 I'm trying to replace some projects to use Spring Data JDBC instead of using JdbcTemplate . Now, I'd like to use it for multiple DataSource s, how can I configure it in Spring Data JDBC? 回答1: There is currently no support for working with two or more DataSource s. You'd have to manually redo what the JdbcRepositoryFactoryBean does. 来源： https://stackoverflow.com/questions/49914310/how-to-configure-multiple-datasources-in-spring-data-jdbc
