Question

我的机器上安装了aerospike server v 3.8.3，我尝试在aql中使用以下命令创建索引：

aql> CREATE INDEX indexA ON namespace.setA(binA) STRING

以下是aql> show indexes命令

的结果

+----------------+--------+------------+---------+-------+------------+-------+------------+------------+
| ns             | bin    | indextype  | set     | state | indexname  | path  | sync_state | type       |
+----------------+--------+------------+---------+-------+------------+-------+------------+------------+
| "namespace"    | "binA" | "NONE"     | "setA"  | "RW"  | "indexA"   | "BinB | "synced"   | "STRING"   |
+----------------+--------+------------+---------+-------+------------+-------+------------+------------+

spring-data-aerospike期望使用以下bin构建索引

+----------------+-----------------+--------+----------+-------+-----------+------------+--------------+
| ns             | bins            | set    | num_bins | state | indexname | sync_state | type         |
+----------------+-----------------+--------+----------+-------+-----------+------------+--------------+
| "user_profile" | "last_activity" | "west" | 1        | "WO"  | "ix1"     | "synced"   | "INT SIGNED" |
+----------------+-----------------+--------+----------+-------+-----------+------------+--------------

文档here和here

中提到了这两种格式

索引创建中存在不兼容性，我应该修复spring-data-aerospike还是修复索引以匹配spring-data-aerospike

中的预期输出

Answer 1

修复spring-data-aerospike ，因为aerospike-server改变了自48f1ae5以来的行为。

在服务器（as/src/base/secondary_index.c）中响应'show indexes'的代码是：

/*
 * Client API to list all the indexes in a namespace, returns list of imd with
 * index information, Caller should free it up
 */
int
as_sindex_list_str(as_namespace *ns, cf_dyn_buf *db)
{
......

您可以在link。

中查看更改

Spring-data-aerospike与aql创建的索引不兼容
