Compressed memory dumps

A method comprising:

• identifying, by a processor, memory regions within a Virtual Address Space (VAS) by scanning the VAS, wherein the memory regions are to be saved to at least one compressed dump file;
• grouping, by the processor, the memory regions into one or more fixed, equal-sized memory buckets;
• spawning, by the processor, parallel threads that cause the processor to execute parallel operations comprising:
• compressing the one or more memory buckets into one or more compressed memory chunks;
• and
• writing the one or more compressed memory chunks to be written to at least one dump file;
• and
• generating, by the processor, a header for the at least one compressed dump file, wherein the header includes a memory structure including metadata regarding at least the respective memory regions and the one or more memory buckets.

A non-transitory computer-readable medium on which is stored a plurality of instructions that, when executed by a processor, cause the processor to:

• scan a header associated with a compressed dump file, wherein the header includes at least a memory region array and a memory bucket array;
• identify, from the memory region array, a memory region ID corresponding to a given compressed memory chunk;
• obtain, from the memory bucket array, a memory bucket ID of a memory bucket including a memory region corresponding to the memory region ID, wherein the memory bucket includes a plurality of memory regions;
• determine an offset of the compressed memory chunk from the memory bucket;
• decompress the compressed memory chunk retrieved at the offset;
• and
• provide to a caller, memory contents obtained upon decompressing the compressed memory chunk.
