如何使用Stargate REST API在HBase中构建更复杂的过滤器层次结构？

Question

样本表

  

HBase的（主）：026：0＆GT;扫描'数据表'

     

ROW COLUMN + CELL

     

key1 column = cf1：col1，   timestamp = 1465135446446，value = value1

     

key1 column = cf1：col2，timestamp = 1465135452934，value = value1

     

key2 column = cf2：col1，timestamp = 1465135471613，value = value2

     

key2 column = cf2：col2，timestamp = 1465135481068，value = value2

     

key3 column = cf1：col1，timestamp = 1465137223212，value = value3

     

key3 column = cf2：col2，timestamp = 1465137232291，value = value3

     

在0.0300秒内完成3行

查询

  

过滤下面任何一个条件

的行      

行键为“key1”，其中Column为{cf1：col1}

     

OR

     

列是{cf2：col2}

预期产出

  

ROW COLUMN + CELL

     

key1 column = cf1：col1，timestamp = 1465135446446，value = value1

     

key2 column = cf2：col2，timestamp = 1465135481068，value = value2

     

key3 column = cf2：col2，timestamp = 1465137232291，value = value3

Answer 1

Base64等效

cf1 => Y2Yx

col1 => Y29sMQ==

key1 => a2V5MQ==

cf2=> Y2Yy

col2 => Y29sMg==

  

运营商（op）：LESS，LESS_OR_EQUAL，EQUAL，NOT_EQUAL，GREATER_OR_EQUAL，GREATER，NO_OP;
