It's been a while since I've done any major work with these and I know some changes have been made since then, but it should not be reading everything into memory nor should it be creating the output XML in memory. The code that I wrote way back when used the EntityListIterator to pull from the database, and streamed small chunks of text for each entity and field out to a file as it iterates over the ELI.
If it's not doing that then some investigation would be necessary to find out why... -David Brett Palmer wrote:
Has anyone used the webtools export utilities to export tables with millions of rows? I have used it on smaller tables, but when I try to export on a large table I get an out of memory error. I believe the webtools utility tries to read the entire table in memory before writing it to the file. We need this functionality to do a major migration from Oracle to postgres. If the functionality doesn't exist we will implement it ourself and contribute it back if anyone is interested. If you have any suggestions please post them to the group.
