README

        
The memtier_benchmark tool provides a --data-import option that allows reading

data and optionally key names from file.

The expected file is a comma delimited file (CSV), with the following

columns:

'dumpflags'     an integer bit-mask flags value which should generally be '0'.

'time'          the time the item was inserted or modified, expressed in 

                seconds since the memcached startup.

'exptime'       item's expiration time, expressed in seconds since the 

                memcached startup.                

'nbytes'        length of item data, in bytes.

'nsuffix'       length of flags+length string associated with the item, in bytes.

'it_flags'      a flags bitmask value.

'clsid'         item's slab class ID.

'nkey'          length of key, in bytes.

'key'           the key itself.

'data'          the data itself.

The 'key' and 'data' columns are enclosed in double quotes.  If data in these

columns contains a double quote, it is quoted (i.e., a single " is encoded as

"").

The data column may contain binary data, including non-ASCII characters, NULLs,

CRs and LFs.

Note: 

  To avoid unnecessary error while passing file.

    1. Add extra 4 bytes in nbytes

    2. Add extra 2 bytes in nkey

    

  Example:

    dumpflags, time, exptime, nbytes, nsuffix, it_flags, clsid, nkey, key, data

    0, 0, 60, 19, 200, 0, 1, 11, 'doxrpshny', 'asdfghjklqwerty'
