Depends on you search pattern. If you never care about scans ordering i.e. you only do point gets to see whether you've already seen an email address, do the hash part.
I'd perfer #1 over #2, because it would let you do efficient key prefix block encoding (FAST_DIFF). -- Lars ________________________________ From: Nurettin Şimşek <[email protected]> To: [email protected] Sent: Wednesday, February 13, 2013 12:35 AM Subject: RowKey design with hashing Hi All, In our project mail adresses are row key.
