Claus Ibsen commented on CAMEL-4356: ------------------------------------ I would suggest the option would be named: fastExistsCheck As its more descriptive what it does: to enable checking for file exists using a faster way. > faster way of testing for file existence > ---------------------------------------- > > Key: CAMEL-4356 > URL: https://issues.apache.org/jira/browse/CAMEL-4356 > Project: Camel > Issue Type: Improvement > Components: camel-ftp > Affects Versions: 2.8.0 > Reporter: Marco Crivellaro > Assignee: Willem Jiang > Priority: Minor > > when storing a file the ftp component checks if the file exists in the > endpoint, this is done by listing the content of the destination folder and > looping through all files listed. > the list operation takes a long time when the destination folder contains > hundreds of files. > instead of listing for all files the component can simply list for the file > it is interested on, this way the number of files contained in destination > folder won't affect the time it takes the producer to process the exchange. > I currently have a case where delivering to an endpoint is taking more than a > minute because of this issue. > Both ftp and sftp libraries used supports listing for a single file so the > changes would be the following: > {code:title=FtpOperations.java} > public boolean existsFile(String name) throws > GenericFileOperationFailedException { > String[] names = client.listNames(name); > if (names == null) { > return false; > } > return (names.lenght >= 1); > } > {code} > {code:title=SftpOperations.java} > public boolean existsFile(String name) throws > GenericFileOperationFailedException { > Vector files = channel.ls(name); > if (names == null) { > return false; > } > return (names.size >= 1); > } > {code} -- This message is automatically generated by JIRA.
