Methods and systems for efficient erasure-coded storage systems

A non-transitory computer-readable storage medium, comprising program instructions, which, when executed by one or more processors of a computing system, perform a method comprising:

• determining an information type of digital information, wherein
• the digital information is to be written to a storage system;
• in response to a determination that the information type is a first information type,
• writing the digital information using a first process, wherein
• the first information type is metadata, and
• the first process comprises
• writing the digital information to a log, and
• writing the digital information to a storage unit of the storage system;
• and
• in response to a determination that the information type is a second information type,
• determining erasure-coded parity information for the digital information, wherein
• the second information type is data, and
• the digital information is to be written to an erasure-coded storage unit of the storage system, and
• writing the digital information using a second process, wherein
• the second process comprises
• writing the digital information and the erasure-coded parity information to the erasure-coded storage unit, without writing the digital information to the log.

A computing system comprising:

• one or more processors, wherein
• the computing system is configured to be communicatively coupled to a storage system;
• and
• a computer-readable storage medium coupled to the one or more processors, comprising program instructions, which, when executed by the one or more processors, perform a method comprising
• determining an information type of digital information, wherein
• the digital information is to be written to the storage system,
• in response to a determination that the information type is a first information type,
• writing the digital information using a first process, wherein
• the first information type is metadata, and
• the first process comprises
• writing the digital information to a log, and
• writing the digital information to a storage unit of the storage system, and
• in response to a determination that the information type is a second information type,
• determining erasure-coded parity information for the digital information, wherein
• the second information type is data, and
• the digital information is to be written to an erasure-coded storage unit of the storage system, and
• writing the digital information using a second process, wherein
• the second process comprises
• writing the digital information and the erasure-coded parity information to the erasure-coded storage unit, without writing the digital information to the log.
