Description

LUCENE-9480 introduced a more efficient method for byte skipping in IndexInput and its subclasses, but the rest of the DataInput implementations are still delegating to DataInput#skipBytesSlowly.

 

This issue tracks optimizing the remaining DataInput skipBytes implementations. Here's the list remaining:

• CompressingStoredFieldsReader (contains an anonymous DataInstance impl internally)
• ByteSliceReader
• ByteBuffersDataInput
• InputStreamDataInput
• PagedBytesDataInput
