System, methods, and media for compressing non-relational database objects

1. A method for compressing objects, comprising:

receiving a request to write a first object including a first key and a first value, wherein the first object is of a given type, to an in-memory, non-relational data store;

receiving a request to write a second object including a second key and a second value, wherein the second object is of the given type, to the in-memory, non-relational data store;

classifying the first object to a compression dictionary based on a value of the first object and/or the key of the first object;

classifying the second object to the compression dictionary based on a value of the second object and/or the key of the second object;

writing the first object to the in-memory, non-relational data store as an uncompressed object before the first object is compressed;

compressing the first object and the second object based on the compression dictionary to form a first compressed object and a second compressed object, respectively;

writing the first compressed object and the second compressed object to the in-memory, non-relational data store; and

determining when multiple uncompressed versions of an object have been written to the in-memory, non-relational data store before the compressed form of a first of the versions has been formed, and preventing the compressed form from overwriting a subsequent version of the object written to the in-memory, non-relational data store.

2. The method of claim 1 , further comprising automatically identifying classification rules for classifying objects.

3. The method of claim 1 , further comprising removing an object from in-memory, non-relational storage if it has been expired or based on total hits on the object during a predefined period and an amount of time since the object was last requested.

4. The method of claim 1 , further comprising: releasing a buffer associated with the uncompressed object.

5. A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for compressing objects, the method comprising:

receiving a request to write a first object including a first key and a first value, wherein the first object is of a given type, to an in-memory, non-relational data store;

receiving a request to write a second object including a second key and a second value, wherein the second object is of the given type, to the in-memory, non-relational data store;

classifying the first object to a compression dictionary based on a value of the first object and/or the key of the first object;

classifying the second object to the compression dictionary based on a value of the second object and/or the key of the second object;

writing the first object to the in-memory, non-relational data store as an uncompressed object before the first object is compressed;

compressing the first object and the second object based on the compression dictionary to form a first compressed object and a second compressed object, respectively;

writing the first compressed object and the second compressed object to the in-memory, non-relational data store; and

determining when multiple uncompressed versions of an object have been written to the in-memory, non-relational data store before the compressed form of a first of the versions has been formed, and preventing the compressed form from overwriting a subsequent version of the object written to the in-memory, non-relational data store.

6. The non-transitory medium of claim 5 , the method further comprising automatically identifying classification rules for classifying objects.

7. The non-transitory medium of claim 5 , the method further comprising removing an object from in-memory, non-relational storage if it has been expired or based on total hits on the object during a predefined period and an amount of time since the object was last requested.

8. The non-transitory computer-readable medium of claim 5 , wherein the method further comprises: releasing a buffer associated with the uncompressed object.

9. A system for compressing objects, comprising:

at least one hardware processor that:

receives a request to write a first object including a first key and a first value, wherein the first object is of a given type, to an in-memory, non-relational data store;

receives a request to write a second object including a second key and a second value, wherein the second object is of the given type, to the in-memory, non-relational data store;

classifies the first object to a compression dictionary based on a value of the first object and/or the key of the first object;

classifies the second object to the compression dictionary based on a value of the second object and/or the key of the second object;

writes the first object to the in-memory, non-relational data store as an uncompressed object before the first object is compressed;

compresses the first object and the second object based on the compression dictionary to form a first compressed object and a second compressed object, respectively;

writes the first compressed object and the second compressed object to the in-memory, non-relational data store; and

determines when multiple uncompressed versions of an object have been written to the in-memory, non-relational data store before the compressed form of a first of the versions has been formed, and prevents the compressed form from overwriting a subsequent version of the object written to the in-memory, non-relational data store.

10. The system of claim 9 , wherein the at least one hardware processor also automatically identifies classification rules for classifying objects.

11. The system of claim 9 , wherein the at least one hardware processor also removes an object from an in-memory, non-relational store when it has been expired or based on total hits on the object during a predefined period and an amount of time since the object was last requested.

12. The system of claim 9 , wherein the at least one hardware processor also: releases a buffer associated with the uncompressed object.
