File:	Maximum allowed size is 50MB.
Description:
Privacy:

If the data you need to attach is more than 50MB, you should create a compressed archive of the data, split it to 50MB chunks, and upload each of them as a separate attachment.

To split a large file:

On *nix platforms use the split command e.g. split -b 50MB <my_large_archive> <my_split_archive_prefix>
On windows use WinZip or a similar utility to split the large file

select * from performance_schema.threads where PROCESSLIST_STATE is not null or PROCESSLIST_ID=2163878 order by thread_id;

select * from performance_schema.metadata_locks;

Attachment: 2.metadata_locks.txt (text/plain), 1.25 KiB.

select * from performance_schema.replication_applier_status_by_worker;

Attachment: 3.replication_applier_status_by_worker.txt (text/plain), 7.53 KiB.
