Class BlockDeserializer

  • All Implemented Interfaces:
    com.fasterxml.jackson.databind.deser.NullValueProvider, com.fasterxml.jackson.databind.deser.ValueInstantiator.Gettable, Serializable
    @Deprecated
public class BlockDeserializer
extends com.fasterxml.jackson.databind.deser.std.StdDeserializer<Block>
    Deprecated.
    BlockSerDeV3 should be used instead
    Uses either an explicit BlockAllocator or a BlockAllocatorRegistry to handle memory pooling associated with deserializing blocks. Blocks are serialized as an Apache Arrow Schema + Apache Arrow Record Batch. If you need to serialize multiple Blocks of the same Schema we do not recommend using this class since it will result in the same schema being serialized multiple times. It may be more efficient for you to serialize the Schema once, separately, and then each Record Batch.

    This class also attempts to make use of the allocator_id field of the Block so that it will reuse the same allocator id when deserializing. This can be helpful when attempting to limit the number of copy operations that are required to move a Block around. It also allows you to put tighter control around which parts of your query execution get which memory pool / limit.
