Feature #150

Cập nhật bởi Tùng Nguyễn cách đây hơn 1 năm

Yêu cầu: Enable compression trên data pool của S3 
 ceph osd pool set CMC-G1.rgw.buckets.data compression_algorithm snappy 
 ceph osd pool set CMC-G1.rgw.buckets.data compression_mode force 

 So sánh kết quả CPU trước và sau khi enable compress ( S3 gateway và các node) 
 Cách test: + Upload file lớn ( 500MB - 1GB)

 ==== 
 Phụ thuộc vào 2 giá trị sau 
 compression_max_blob_size 
 compression_min_blob_size

 ==== 
 rgw_obj_stripe_size mặc định là 4M 
 sau khi upfile thì check số lượng compress_success

 Test upload file 994MB đang gặp tình trạng sau: 
 Test lần 1: compressed còn 747MB -> chưa load đầy đủ object 
 Test lần 2: compressed còn 885 MB 
 Test lần 3: không compressed
