Apache Druid

@here is the any max limit on number of prefixes in inputsource of type s3. or any max payload size limit on that ?
```"ioConfig": {
      "type": "index_parallel",
      "inputSource": {
        "type": "s3",
        "objectGlob": "**.json",
        "uris": ["<s3://foo/bar/file.json>", "<s3://bar/foo/file2.json>"]
      },```

I never tried with more than few dozen records, so I'm not sure.

But prob the best solution is to structure them into a prefix structure, so instead of "uris"
```        "uris": ["<s3://foo/bar/file.json>", "<s3://bar/foo/file2.json>"]```
you can use
```        "prefixes": ["<s3://foo/bar/>", "<s3://bar/foo/>"]```


I do not think there is any specific limit. You might use splithintspec to create separate tasks depending on the size of the data.

may be there is limit on max size of input spec if I am not able to submit task with more than 512Kb input spec
