class CachedEagerAvroSchemaManager extends CachedAvroSchemaManager

Implementation of CachedAvroSchemaManager that loads all the schemas into the cache at startup and doesn't perform any other accesses to the storage: each retrieve is performed onto the cache.

  13. def generateAvroSingleObjectEncoded(avroPayload: Array[Byte], schema: Schema): Array[Byte]

    Create an array that creates a Single-Object encoded byte array.

    Create an array that creates a Single-Object encoded byte array. By specifications the encoded array is obtained concatenating the V1_HEADER, the schema id and the avro-encoded payload.

    avroPayload

    avro-serialized payload

    schema

    the schema used to encode the payload

    returns

    a Single-Object encoded byte array

    Checks if all the input Schema elements are already in the cache. Then, it performs an insert on the storage for all the elements not found on the cache, and then returns each input schema paired with its ID.

    schemas

    all the Schema that should be registered

    returns

    a sequence of pairs of the input schemas associated with their IDs
