Module arrow::ipc::gen::Message [−][src]
Structs
BodyCompression | Optional compression for the memory buffers constituting IPC message bodies. Intended for use with RecordBatch but could be used for other message types |
BodyCompressionArgs | |
BodyCompressionBuilder | |
BodyCompressionMethod | Provided for forward compatibility in case we need to support different strategies for compressing the IPC message body (like whole-body compression rather than buffer-level) in the future |
CompressionType | |
DictionaryBatch | For sending dictionary encoding information. Any Field can be dictionary-encoded, but in this case none of its children may be dictionary-encoded. There is one vector / column per dictionary, but that vector / column may be spread across multiple dictionary batches by using the isDelta flag |
DictionaryBatchArgs | |
DictionaryBatchBuilder | |
FieldNode | |
Message | |
MessageArgs | |
MessageBuilder | |
MessageHeader | |
MessageHeaderUnionTableOffset | |
RecordBatch | A data header describing the shared memory layout of a “record” or “row” batch. Some systems call this a “row batch” internally and others a “record batch”. |
RecordBatchArgs | |
RecordBatchBuilder |
