BytesInputCompressor getCompressor(CompressionCodecName codecName);
+ /**
+ * Returns a {@link BytesInputCompressor} instance for the specified codec
name and compression level.
+ * <p>
+ * The compression level controls the trade-off between compression speed
and ratio. The valid range
+ * and meaning of the level is codec-specific:
+ * <ul>
+ * <li>ZSTD: 1 (fastest) to 22 (best compression), default 3</li>
Review Comment:
The ZSTD range here is now broader because `validateZstdLevel` uses the zstd
library min/max levels. Please update this wording to avoid documenting `1-22`
only.
