Aerospike Exception Error Code 4 Parameter Error when doing a put through java client

Question

I am processing an avro file with a list of records and doing a client.put for each record to my local Aerospike store.

For some reason, put for a certain number of records is succeeding and it's not for the rest. I am doing this -

client.put(writePolicy, recordKey, bins);

The related values for the failed call are -

namespace = test

setname = test_set

userkey = some_string

write policy = null

Bins -

is_user:1

prof_loc:530049,530046,530032,530031,530017,530016,500046

rfm:Platinum

store_browsed:some_string

store_purch:some_string

city_id:null

Log Snippet -

com.aerospike.client.AerospikeException: Error Code 4: Parameter error at com.aerospike.client.command.WriteCommand.parseResult(WriteCommand.java:72) at com.aerospike.client.command.SyncCommand.execute(SyncCommand.java:56) at com.aerospike.client.AerospikeClient.put(AerospikeClient.java:338)

What could possibly be the issue?

Any hint in server-side log file (/var/log/aerospike/aerospike.log) ? Also, you can check where that error is raised from the Github repo: github.com/aerospike/aerospike-server/…✓ — Manuel Arwed Schmidt

Finally. Resolved!

I was using the REPLACE RecordsExistsAction in this case. Any bin with null value will fail in this configuration. Aerospike treats a null value in a bin as equivalent to removing that bin value from the record for a key. Thus REPLACE configuration doesn't make sense for such an operation, and hence a parameter error - Invalid DB operation.

UPDATE config on the other hand will work perfectly fine.

Glad you were able to solve it. Hint: Once you 'accept' your own answer (green tick), this question will be visibly closed and people won't get here when searching for questions they can answer.

Did that. I had to wait for 24 hours

Aerospike allows reading and writing with great flexibility. For developers to harness this functionality, Aerospike exposes great number of variables on both Policy and WritePolicy, which at times can be intimidating and error prone to beginners. Parameter error simply means that some of the configurations are not in coherence. An easy start would be to use the default read or write policy, which can be obtained by passing null as the policy. Eg:

aeroClient.put(null, key, new Bin("binName", object));

Below is aerospike put method code snippet

    public final void put(WritePolicy policy, Key key, Bin... bins) throws AerospikeException {
    if (policy == null) {
        policy = writePolicyDefault;
    }
    WriteCommand command = new WriteCommand(cluster, policy, key, bins, Operation.Type.WRITE);
    command.execute();
}

I recently got this error, because the expiration value that I was using in writePolicy was more than the default expiration time for the cache
