Abstract
A system, method, and apparatus are provided for facilitating reverse reading of sequentially stored variable-length data records. Each record is stored with accompanying size metadata that identifies the size or length of the record. Further, if the length of a given record is greater than a threshold (e.g., 127 bytes when the length is stored with variable-length quantity encoding), such that more than one byte (or other storage unit) is needed to store the record length, an additional byte (or other unit) is configured to store the size/length of the record length (e.g., the number of bytes required to store the record length). The most significant bit of the additional byte is set to 1, so that during reverse reading, the location and size of the record length value can be quickly determined.
