How can I query data from HBase table in millisecond?
<p>I'm writing a interface to query pagination data from Hbase table ,I query pagination data by some conditions, but it's very slow .My <code>rowkey</code> like this : <code>12345678:yyyy-mm-dd</code> , length of 8 random Numbers and date .I try to use Redis cache all <code>rowkeys</code> and do pagination in it , but it's difficult to query data by the other conditions  .
  I also consider to design the secondary index in Hbase , and I discuss it with colleagues ,they think the secondary index is hard to maintain .
  So , who can give me some ideas?</p>
