java - Spring Batch - Recovery after Error -

-



i have spring batch job itemprocessor can possibly fail exception. if happens have itemprocesslistener in place handles recovery (marking item failed not picked in next run).

that solution works charm 'regular' exceptions, i've experienced java.lang.outofmemoryerror: java heap space error onprocesserror() not called , item not excluded in next run.

i noticed jobexecutionlistener.afterjob() called job parameters of failed execution , query all items of execution again , mark them failed.

is there better approach problem?

basically onprocesserror ill-named. listens exceptions, not errors. java discourages handling errors via catch-blocks. reason is, jvm signals fault not in programming in configuration of vm via error. should taken strong indicator, vm-setup needs correction.

in case, write outofmemoryerror occurs if memory demand higher memory, has been assigned java-job via -xmx/xms startparameters. either assign little memory or consume of it. should fixed, not caught via technical trick.

first of all, should find out causes error. maybe need assign more memory, of algorithms greedy in memory consumption , not unlikely, have memory leak root cause.

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
