`Scanner` `createScannerByKey`(`byte[],` byte[]) | Get a scanner that covers a portion of TFile based on keys.
`Scanner` `createScannerByKey`(`RawComparable,` RawComparable) | Get a scanner that covers a specific key range.
`Scanner` `createScannerByRecordNum`(`long,` long) | Create a scanner that covers a range of records.
`long` `getRecordNumNear`(`long`) | Get the RecordNum for the first key-value pair in a compressed block whose byte offset in the TFile is greater than or equal to the specified offset.
