• add support to connect private s3 compatible host (eg: ceph rgw) from pandas

  Just set host url / access key / secret key by dcutils.mix_pd_s3():

  from dcutils import mix_pd_s3
  
  s3_host = 'http://xxx.xxx.xxx.xxx:12345'
  access_key = 'xxxxxxxxx'
  secret_key = 'xxxxxxxxxxxxxxxxxxxxxxx'
  
  mix_pd_s3(s3_host, access_key, secret_key)

  Then, read/write data from s3 host with url "s3://<bucket>/<object_name>"

  import pandas as pd
  
  local_file = 'foo.csv'
  s3_bucket = 'test'
  s3_object = "s3://%s/%s" % (s3_bucket, local_file)
  
  # load orignal data from file system
  df = pd.read_csv(local_file)
  
  # save df into s3
  df.to_csv(s3_object, index=False, header=True)
