Question

我正在尝试从命令行查询aerospike数据库。我想查询一个名为Users的集合。

$ aql -h remote.myserver.com -p 3000
Aerospike Query Client
Version 3.13.0.1
C Client Version 4.1.6
Copyright 2012-2016 Aerospike. All rights reserved.
aql> select * from test.Users
Error: (9) Timeout: timeout=1000 iterations=1 failedNodes=0 failedConns=0

当我使用CLI选项时，如何增加超时？该表仅有27个记录。

提前致谢。

1）在最新的aql工具上，您可以使用 -T 命令行选项。

-T， - timeout设置命令的超时（ms）。默认值：1000

aql -u
aql: option requires an argument -- 'u'

2）在aql交互模式下，您可以通过修改

来设置超时

TIMEOUT 设置

aql> set  TIMEOUT 100000
TIMEOUT = 100000
aql>

以下是可以在交互模式下修改的设置。

  SETTINGS
        ECHO                          (true | false, default false)
        OUTPUT                        (TABLE | JSON | MUTE | RAW, default TABLE)
        OUTPUT_TYPES                  (true | false, default true)
        TIMEOUT                       (time in ms, default: 1000)
        VERBOSE                       (true | false, default false)
        LUA_USERPATH                  <path>, default : /opt/aerospike/usr/udf/lua
        LUA_SYSPATH                   <path>, default : /opt/aerospike/sys/udf/lua
        USE_SMD                       (true | false, default false)
        RECORD_TTL                    (time in sec, default: 0)
        RECORD_PRINT_METADATA         (true | false, default false, prints record metadata)
        REPLICA_ANY                   (true | false, default false)
        KEY_SEND                      (true | false, default false)
        DURABLE_DELETE                (true | false, default false)
        FAIL_ON_CLUSTER_CHANGE        (true | false, default true, policy applies to scans)
        SCAN_PRIORITY                 priority of scan (LOW, MEDIUM, HIGH, AUTO), default : AUTO
        NO_BINS                       (true | false, default false, No bins as part of scan and query result)
        LINEARIZE_READ                (true | false, default false, Make read linearizable, applicable only for namespace with strong_consistency enabled.)

3）上述设置也可以在aql脚本中设置，并使用

调用

aql -f <aql_script>

$ cat test.aql 
INSERT INTO test.demo (PK, foo, bar) VALUES ('key1', 123, 'abc')
SET TIMEOUT 150000
select * from test.demo

$ aql -f test.aql 
INSERT INTO test.demo (PK, foo, bar) VALUES ('key1', 123, 'abc')
OK, 1 record affected.

SET TIMEOUT 150000
TIMEOUT = 150000
select * from test.demo
+-----+-------+
| foo | bar   |
+-----+-------+
| 123 | "abc" |
+-----+-------+
1 row in set (0.392 secs)
