Hi,

You can point a file-based input format to a directory and the input format should read all files in that directory.

That works as well for TableSources that are internally use file-based input formats.

Is that what you are looking for?

Best, Fabian

Hi all,

I'm wondering if it's possible and what's the best way to achieve the loading of multiple files with a Json source to a JDBC sink ?

I'm running Flink 1.7.0

Let's say I have about 1500 files with the same structure (same format, schema, everything) and I want to load them with a *batch* job

Can Flink handle the loading of one and each file in a single source and send data to my JDBC sink?

I wish I can provide the URL of the directory containing my thousand files to the batch source to make it load all of them sequentially.

My sources and sinks are currently available for BatchTableSource, I guess the cost to make them available for streaming would be quite expensive for me for the moment.

Have someone ever done this?

Am I wrong to expect doing so with a batch job?

All the best
