> But this way there is no checkpointLocation. How do you manage the offset?
As I said, we're using `GlueContext.forEachBatch` which allows you to
specify the checkpoint location as follows:
```
glue_context.forEachBatch(
frame=read_stream,
batch_function=process_batch,
options={
"windowSize": job_args["TRIGGER_PROCESSING_TIME"],
"fanout-enabled": job_args["FANOUT_ENABLED"],
"checkpointLocation": job_args["CHECKPOINT_LOCATION"],
"persistDataFrame": "false",
}
)
```
The equivalent call to `writeStream.forEachBatch` would be something like:
`read_stream.writeStream.foreachBatch(process_batch).trigger(processingTime=windowSize).option("checkpointLocation",
checkpointLocation)`
As can be seen in the Glue source code I linked above, here:
