1. 掃描值等於sku188的記錄

scan 'test1', FILTER=>"ValueFilter(=,'binary:sku188')"

ROW COLUMN+CELL
user1_ts2 column=f:c1, timestamp=1589192112394, value=sku188
1 row(s) in 1.5920 seconds

2. 掃描值包含88的記錄

scan 'test1', FILTER=>"ValueFilter(=,'substring:88')"

ROW COLUMN+CELL
user1_ts2 column=f:c1, timestamp=1589192112394, value=sku188
user2_ts5 column=f:c2, timestamp=1589192112472, value=sku288
2 row(s) in 13.9120 seconds

3. 掃描列名包含'c2', 並且列值包含'88'的記錄

scan 'test1', FILTER=>"ColumnPrefixFilter('c2') AND ValueFilter(=,'substring:88')"

ROW COLUMN+CELL
user2_ts5 column=f:c2, timestamp=1589192112472, value=sku288
1 row(s) in 1.5880 seconds

4. 掃描列名包含'c', 並且列值包含'88'的記錄

scan 'test1', FILTER=>"ColumnPrefixFilter('c') AND ValueFilter(=,'substring:88')"

ROW COLUMN+CELL
user1_ts2 column=f:c1, timestamp=1589192112394, value=sku188
user2_ts5 column=f:c2, timestamp=1589192112472, value=sku288
2 row(s) in 3.1850 seconds

5. 掃描列名包含's'且有列值包含'123', 或者列值包含'222'的記錄

scan 'test1', FILTER=>"ColumnPrefixFilter('s') AND ( ValueFilter(=,'substring:123') OR ValueFilter(=,'substring:222') )"

ROW COLUMN+CELL
user1_ts3 column=f:s1, timestamp=1589192112432, value=sku123
user2_ts6 column=f:s1, timestamp=1589192114562, value=sku222
2 row(s) in 1.4670 seconds

6. 掃描rowkey前綴爲'user1'的記錄

scan 'test1', FILTER => "PrefixFilter ('user1')"

ROW COLUMN+CELL
user1_ts1 column=f:c1, timestamp=1589192122941, value=sku1
user1_ts2 column=f:c1, timestamp=1589192112394, value=sku188
