phoenix索引操作

1，创建本地索引  create local index "IDX_E_voucher_union" on "Fvr_voucher"("cf"."fowner","cf"."fdate");

2. 创建全局索引  create index "IDX_E_voucher_union" on "Fvr_voucher"("cf"."fowner","cf"."fdate");

3.查看索引表  !tables

4.删除表   drop index "IDX_E_voucher_union" on "Fvr_voucher";

1.查HBase索引：

list

2。使Hbase索引失效：

disable "_LOCAL_IDX_E_voucher_union"

3.删除HBase索引：

drop "_LOCAL_IDX_E_voucher_union"

查询是否使用索引

EXPLAIN    SELECT * FROM "Fvr_voucher" WHERE  "fowner"='1' LIMIT 15

查询结果：

CLIENT 3-CHUNK PARALLEL 1-WAY FULL SCAN OVER
Fvr_voucher   （全部扫描，未使用索引）

CLIENT 3-CHUNK SERIAL 3-WAY RANGE SCAN OVER
_LOCAL_IDX_E_voucher_union [-32764,1,'1']  （部分扫描，使用索引）
