ChainSQL converts SQL statements that operate on the database into transactions on the blockchain network. Transaction data is written sequentially to the log system (blocks), so the log system (blocks) records the operation of the database, while combing through the original logs to index the location of these operations in the log system. How logs are synchronized, how to achieve consistency, and failure recovery are fundamental issues that all distributed systems need to address.
The log framework is divided into three categories: log facade, log implementation library and log adapter. JCL, SLF4j, Jboss-logging are all log facades, while real people are log implementation libraries, commonly Log4j, Log4j2, Logback, JUL, and log adapters are required when facades do not match implementation libraries. Of course, 90 percent of the projects now use slf4j and logback, so you can't care much about the selection of the log framework. But if you aspire to be an architect, the choice of framework is a required course, or you have to understand.
