Thanks for downloading InfiniDB and checking it out.

There is a number of places within the code where disk read are performed based on there needs, but here is the primary areas where the writing of the database system files take place:

The WriteEngine code interfaces with the db files on behalf of DML/DDL and the bulk load program cpimport.

The primary functions employed by cpimport to write to the db files are:

O ColumnBuffer::writeToFile() in writeengine/bulk/we_colbuf.cpp
O DbFileOp::writeDBFileDict() in writeengine/shared/we_dbfileop.cpp

The primary functions employed by DML to insert rows to the db files are:

O DbFileOp::writeDBFileFbo() in writeengine/shared/we_dbfileop.cpp
O DbFileOp::writeDBFile() in writeengine/shared/we_dbfileop.cpp
