No fast way to get the count of records of a table without scanning and counting, especially when you want to get the accurate count. By design the data/cells of a same record/row can scatter in many different HFiles and memstore, so even we can record the count of records of each HFile as meta in FileInfo, we still need to de-dup to get the accurate total count, which only can be achieved by scanning. ________________________________________ 发件人: Ramasubramanian Narayanan [[email protected]] 发送时间: 2013年9月10日 16:07 收件人: [email protected] 主题: Fastest way to get count of records in huge hbase table?
Dear All, Is there any fastest way to get the count of records in a huge HBASE table with billions of records? The normal count command is running for a hour with this huge volume of data.. regards, Rams
