How to set environment variable KEY_SEND with persistence in Aerospike? - aerospike

Question

https://www.aerospike.com/docs/tools/aql/settings.html
The documentation says -
The setting values set using aql are valid only for the current
session. A new invoking of aql would have the default values.
So, following aql will last only for a session -
SET KEY_SEND TRUE
But, how to make persisting changes?
Basically, we want to make sure PKs are returned when fetch is done via application.

Answer 1

aql is a command line tool and not intended to build applications.
There is a plethora of high performing Aerospike Client (python, Java, C, etc).
Please see:

And Send Key with Java client example:
https://github.com/aerospike/aerospike-client-java/blob/master/examples/src/com/aerospike/examples/StoreKey.java
And for python client here is some info on the key_send policy:
https://www.aerospike.com/apidocs/python/aerospike.html#aerospike.POLICY_KEY_SEND
That said, you could set the KEY_SEND or TIMEOUT when making the command call and pass the options as a semicolon separated list.
aql -c "set key_send true;INSERT INTO test.demo (PK, foo, bar) VALUES ('key1', 123, 'abc');select * from test"
set key_send true
KEY_SEND = true
INSERT INTO test.demo (PK, foo, bar) VALUES ('key1', 123, 'abc')
OK, 1 record affected.
select * from test
+--------+-----+-------+
| PK | foo | bar |
+--------+-----+-------+
| "key1" | 123 | "abc" |
+--------+-----+-------+
1 row in set (0.380 secs)
This would also work using the aql -f option and passing a file with both options and command
