Changing large in-memory data to file based operation
Hello Camel Experts,
Currently we have something of below route (as simplified version), where we keep reading records 1000 at a time and keep formatting and holding in memory.
Current Simplified Solution:
Generally the data is small and we kept in-memory, we want to improve the same now to safe-guard any in-memory problem. In our landscape we can use 'tmp' storage to hold the file. So we plan to change it like this
Possible Modified Solution:
When locally tried the solution, we see it works - Camel understand 'java.io.File' object & writes to SFTP.
Question 1 - Would camel load it in memory completely before writing to SFTP?
Question 2 - If yes, how can we solve this problem - does some way of streaming works?
Checked : http://www.catify.com/2012/07/09/parsing-large-files-with-apache-camel/ already but they are holding in memory.
Limitation: We don't want to write in chunks to sftp because of the complexity of some data have to written out-of-order.
