Hi Jayesh, Thanks for the analysis. As I found no C/C++ API for HSQL, JDBC is needed to connect [1]. Then, there's information_schema support in HSQL [2]. Then, part of the research is to connect the code that reads the db with C/C++, without intermediate files, and ideally without extra processes.
