61M csv file cause Heap error on JVM with 1 GB limit
I'm new to Camel, but have followed advice on various fora to produce the
below route:
Picks up a csv file, splits into lines and unmarshals each line into a Map
to be inserted
into a database, as named parameters.
The route works (database gets updated), when I use a subset of data (up to
30,000 lines).
However, my full file contains 115,000 lines. That file produces the
stacktrace below.
How must this route be changed to be able to accommodate the full 115,000
line file? (I'm trying to stick to a XML DSL solution)
<route>
<from uri="direct:dbload"/>
<pollEnrich>
<simple>file:{{ftp.unzipFolder}}/?fileName={{ftp.unzipName}}</simple>
</pollEnrich>
<split parallelProcessing="true" streaming="true">
<tokenize token="\r\n"/>
<filter id="_filter1">
<simple>${header.CamelSplitIndex} > 0</simple>
<pipeline id="_pipeline1">
<unmarshal>
<csv delimiter="," formatName="EXCEL"
useMaps="true">
<header>id</header>
</csv>
</unmarshal>
</pipeline>
</filter>
<transform>
<simple>${body[0]}</simple>
</transform>
<to id="_to3"
uri="sql:classpath:/assembly/etc/db-insert.sql?dataSource=dataSource"/>
</split>
</route>

Thanks for the reply.
I'm posting the solution here in case anybody else falls into the same trap
I did:
My route is splitting the file on Windows/Dos line-endings CR-LF.
My input file had Unix (LF) line-endings, though.
I believe that was why the route was trying to process the entire file at
once.
Once I corrected the line-endings on the input file, the entire file loaded
successfully
(in less than 5 minutes).

At first I thought you were reading the whole file at once but it seems you
are splitting it and use streaming. I am not sure if it is something to do
with the ftp operation. Why not have a route that first moves/copies the
file from the ftp server to a local folder. Then let another route get
triggered to pick up that file use streaming and splitter to divide the
file.
