Data storage methods, apparatuses, devices, and storage media

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• receiving data to be stored, wherein the data comprise data corresponding to a plurality of fields;
• determining whether a size of the data exceeds a predetermined threshold;
• and
• in response to determining that the size of the data exceeds the predetermined threshold:
• splitting a portion of the data to obtain data blocks;
• determining block identifiers of the data blocks based on a sequence of the data blocks;
• storing a data identifier of the data and the block identifiers of the data blocks that correspond to each other;
• storing a first key-value pair, wherein a key of the first key-value pair comprises a data identifier of the data, and a value of the first key-value pair comprises a range of the block identifiers;
• storing second key-value pairs, wherein a key of a second key-value pair comprises a block identifier, and a value of the second key-value pair comprises a corresponding data block;
• and
• storing a first portion of the data blocks and corresponding block identifiers in a graph database.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• receiving data to be stored, wherein the data comprise data corresponding to a plurality of fields;
• determining whether a size of the data exceeds a predetermined threshold;
• and
• in response to determining that the size of the data exceeds the predetermined threshold:
• splitting a portion of the data to obtain data blocks;
• determining block identifiers of the data blocks based on a sequence of the data blocks;
• storing a data identifier of the data and the block identifiers of the data blocks that correspond to each other;
• storing a first key-value pair, wherein a key of the first key-value pair comprises a data identifier of the data, and a value of the first key-value pair comprises a range of the block identifiers;
• storing second key-value pairs, wherein a key of a second key-value pair comprises a block identifier, and a value of the second key-value pair comprises a corresponding data block;
• and
• storing a first portion of the data blocks and corresponding block identifiers in a graph database.
