Are there any limitations to the file size or events when importing data using an object store collector (s3, azure, gcp, on-prem obj store)?
Individual event size limitations are controlled by the event breaker definitions applied to the Source. Default is 50 KB max size. Overall files (objects) are not limited per se, but remember that objects have to be downloaded before events can be extracted. And while decompression is done in a streaming fashion so disk space won’t be all that impacted, a large file can take more CPU cycles than expected.
