Aerospike metadata usage

,
1

I am saving data to Aerospike using 2 modes :

  1. Aerospike jtdaava client
  2. Spring boot + Spring data

When using client, I am just seeing the data I had saved. When using the Spring boot + data combo, there is a property “ASpikeMetaData” being saved.

I am able to query both the data sets using Spring data and is working fine.

  1. Point is why and how is the “ASpikeMetaData” being saved and generated?

  2. Secondly, what is the utilitity of “ASpikeMetaData”, does it have any impact on performance (storage vs speed) ?

  3. Third, if needed, how can I remove it while saving data from Spring boot + data?
