List Record Details

explain select is available in Aerospike Tools package 3.6.1 and above.

The following command displays details for a single record:

explain select * from <ns>.<set> where PK=<primary key value>

Example:

aql> explain select * from test.uqr where PK=1
[
{
"SET": "uqr",
"DIGEST": "42 7A 64 AE 7B 80 EE 02 3D B8 E9 00 8A F3 FF B0 7F DA EB 58",
"NAMESPACE": "test",
"PARTITION": 2626,
"STATUS": 2,
"UDF": "FALSE",
"KEY_TYPE": "STRING",
"TIMEOUT": 1000,
"NODE": "1771FE6C15290C00",
"POLICY": "AS_POLICY_REPLICA_MASTER",
"KEY_POLICY": "AS_POLICY_KEY_SEND"
}
]

Where:

  • “SET” is the set name for the record.
  • “DIGEST” is the digest for the record.
  • “NAMESPACE” is the namespace for the record.
  • “PARTITION” is the partition where the record lives. The partition value is between 1 and 4095.
  • “STATUS” is the status of the operation. It will be the code as returned by the client for the record. E.g: 0 is AEROSPIKE_OK and 2 is AEROSPIKE_ERR_RECORD_NOT_FOUND. See here for list of generic error codes in C - Error Codes.
  • “UDF” tells if the AQL command was run as part of a UDF.
  • "KEY_TYPE" is the type of the key (string/numeric etc) that was sent to the server.
  • “TIMEOUT” is the timeout for the AQL command.
  • “NODE” is the ID of the node where the master record currently lives. The node ID might change during migrations.
  • “POLICY” is the replica read policy that the client can set when reading the record. Two possible values are:
    1) AS_POLICY_REPLICA_MASTER (which is by default) to set the reads to go only to it's master copy and,
    2) AS_POLICY_REPLICA_ANY to read in a round-robin operation on all it's replica copies. Set the policy to AS_POLICY_REPLICA_ANY by executing set replica_any true in AQL.
  • “KEY POLICY” indicates whether the client had sent the key and digest to the server or just the digest. Two possible values are:
    1) AS_POLICY_KEY_SEND if the key was sent along with the digest, and
    2) AS_POLICY_KEY_DIGEST if only the digest was sent.
