Daniel Xiaodan Zhou updated DBUTILS-83:
---------------------------------------
Attachment: BatchUploader.java
> Add "BatchUploader" (related to DBUTILS-78 but different)
> ---------------------------------------------------------
>
> Key: DBUTILS-83
> URL: https://issues.apache.org/jira/browse/DBUTILS-83
> Project: Commons DbUtils
> Issue Type: New Feature
> Affects Versions: Nightly Builds
> Reporter: Daniel Xiaodan Zhou
> Priority: Minor
> Attachments: BatchUploader.java
>
>
> I have created a BatchUploader class in one of my project, and thought I
> might contribute it to DbUtils.
> It is similar to DBUTILS-78, but is different. It is basically a
> "producer-consumer" queue, where you application produce rows, and
> BatchUploader "consumes" the rows and write them back to the database.
> DBUTILS-78 also uses multi-threading, but it doesn't have the
> "producer-consumer" queue. So you could imagine cases where you add too many
> rows in a batch before run executeBatch() and cause "Java Out of Memory".
> Also, BatchUploader only uses simple Thread class, so it's more compatible to
> other Java libraries compared to using ExecutorService/Future.
> Here's how you use BatchUploader in you application:
> uploader = new BatchUploader(threadName, dbConnection, sqlStmt);
> uploader.start();
> while (...) {
> uploader.put(...); // here you put each row in the queue
> }
> uploader.accomplish();
> // some other code ...
> uploader.join(); // wait the uploader to finish before moving to the rest of
> the code.
> // continue running ...
> The code attached is directly copied from my project. If people here think it
> should go into DbUtils, I can add more javadoc and remove the specific things
> that were used in my project to make it more general.
