Hi, baseX team. I have some problems of loading xml files into the database of BaseX. I am comparing the time to load xml files into database, there are 2 ways to load: Loading all the folder into the database and Loading each file into the database. The time to load all the folder and the time to load each file have a big difference. The time to load all the folder into the datebase is 84ms, whereas the time to load each file into the database is 912 ms. I have written the 2 ways to load in C#. The following code is to load all the folder into the datebase: private void CreateDBAndLoadDirectory(string directoryPath) { this.contextDirectory = new Context(); this.serverDirectory = new org.basex.BaseXServer(this.contextDirectory); Set.execute("createfilter", "*" + this.fileExtension, this.contextDirectory); Set.execute("CACHEQUERY", true, this.contextDirectory); Set.execute("SERIALIZE", false, this.contextDirectory); Set.execute("CHOP", true, this.contextDirectory); Set.execute("DBPATH", this.dbPath, this.contextDirectory); new CreateDB(this.dbDirectory, directoryPath).execute(this.contextDirectory); } And the following code is to load each file into the database: private void CreateDBAndLoadFiles(string directoryPath) { this.contextFile = new Context(); this.serverFile = new org.basex.BaseXServer(this.contextFile); Set.execute("CACHEQUERY", true, this.contextFile); Set.execute("SERIALIZE", false, this.contextFile); Set.execute("CHOP", true, this.contextFile); Set.execute("DBPATH", this.dbPath, this.contextFile); new CreateDB(this.dbFile).execute(this.contextFile); string[] fileList = Directory.GetFiles(directoryPath, "*" + this.fileExtension,SearchOption.AllDirectories); foreach (string fileName in fileList) { string path = fileName.Substring(this.otxPath.Length + 1); new Add(path, fileName).execute(this.contextFile); new Optimize().execute(this.contextFile); } } I don't know if I have made mistakes in these codes or not? I want to ask about the fastest way to load each file into the database.
