行列+单元格

key1 列=cf1:col1, 时间戳=1465135446446，值=值1

key1 列=cf1:col2，时间戳=1465135452934，值=value1

key2 列=cf2:col1，时间戳=1465135471613，值=value2

key2 列=cf2:col2，时间戳=1465135481068，值=value2

key3 列=cf1:col1，时间戳=1465137223212，值=value3

key3 列=cf2:col2，时间戳=1465137232291，值=value3

【参考方案1】：

Base64 等效项

cf1 => Y2Yx

col1 => Y29sMQ==

key1 => a2V5MQ==

cf2=> Y2Yy

col2 => Y29sMg==

OPERATORS(op)：LESS、LESS_OR_EQUAL、EQUAL、NOT_EQUAL、GREATER_OR_EQUAL、GREATER、NO_OP；

过滤器列表（操作）：MUST_PASS_ALL、MUST_PASS_ONE
