Parameters

stream  Stream

The stream to read from.

offset  Int64

The position in the stream to start reading.

size  Int64

The number of bytes to read from the stream.

allowRecordReuse  Boolean

if the record reader may re-use the same Utf8String instance for every record; if it must create a new instance for every record.

The reader will start reading at offset. If offset is larger than zero, the reader will seek ahead to the start of the next record and read from there.

The reader will read a whole number of records until the start of the next record falls after offset + size. Because of this, the reader can read more than size bytes.

The reader will check if stream implements IRecordInputStream with RecordOptions set to DoNotCrossBoundary. If so, if offset falls on a structural boundary the reader will not seek ahead because it knows structural boundaries are record boundaries; if offset + size falls on a structural boundary, the reader is guaranteed to not read beyond offset + size.
