STORAGE AND ACCESS TIME FOR RECORDS

摘要

In an example embodiment, information to be stored in a record is received, the information comprising at least two pieces of data of at least two different data types, at least one of the data types being of a variable length. Then a data structure is created. The data structure comprises a first portion indicating an offset size, a second portion comprising an offset pointing to a third portion of the data structure, the third portion of the data structure containing a table of offsets, each offset in the table of offsets pointing to a different one of the at least two pieces of data, the at least two pieces of data stored in a fourth portion of the data structure. A schema is also created for the data structure, the schema storing metadata for the at least two pieces of data.

1. A computer-implemented method comprising:
receiving information to be stored in a record, the information comprising at least two pieces of data of at least two different data types, at least one of the data types being of a variable length; creating a data structure, the data structure comprising a first portion indicating an offset size, a second portion comprising an offset pointing to a third portion of the data structure, the third portion of the data structure containing a table of offsets, each offset in the table of offsets pointing to a different one of the at least two pieces of data, the at least two pieces of data stored in a fourth portion of the data structure; creating a schema for the data structure, the schema storing metadata for the at least two pieces of data; and storing the data structure and the schema in a database.
