Methods and systems of garbage collection and defragmentation in a distributed database
View Patent ↗In one aspect, a computerized-method of a distributed database includes the step of providing a first data partition with a set of data. The method includes the step of providing a second data partition with a replica of the first set of data. The method includes the step of identifying a client application accessing the first data partition and the second data partition. The method includes the step of performing a reclamation operation on the second data partition. The method includes the step of informing the client application that a read operation is prohibited during the reclamation operation.
1. A computerized-method of a distributed database comprising:
providing a first data partition with a first set of data;
providing a second data partition with a replica of the first set of data;
identifying a client application accessing the first data partition and the second data partition, wherein the client application is allowed to implement a write operation to the second partition during a reclamation operation;
performing the reclamation operation on the second data partition, wherein the reclamation operation comprises a garbage collection operation on the second data partition, wherein the reclamation operation comprises a defragmentation operation; and
informing the client application that a read operation is prohibited during the reclamation operation, and
wherein the distributed database comprises a flash-optimized in-memory not-only SQL (NoSQL) database.
2. The computerized-method of claim 1 , wherein the first data partition comprises a solid-state device drive.
3. The computerized-method of claim 2 , wherein the second data partition comprises another solid-state device drive.
4. The computerized-method of claim 2 further comprising:
determining that the reclamation operation has finished.
5. The computerized-method of claim 4 further comprising;
communicating to the client application that the read operation to the second partition is allowed.
6. A computerized system comprising:
at least one processor configured to execute instructions;
at least one memory containing instructions when executed on the processor, causes the processor to perform operations that:
provide a first data partition with a first set of data;
provide a second data partition with a replica of the first set of data;
identify a client application accessing the first data partition and the second data partition;
implement a reclamation operation on the second data partition, wherein the reclamation operation comprises a defragmentation operation on the second data partition; and
inform the client application that read operations to the second partition are prohibited during the reclamation operation, and
wherein the distributed database comprises a flash-optimized in-memory not-only SQL (NoSQL) database.
7. The computerized-system of claim 6 , wherein the client application is allowed to implement a write operation to the second partition during the reclamation operation.
8. The computerized-system of claim 7 , wherein the reclamation operation comprises a garbage collection operation.
9. The computerized-system of claim 8 , wherein the first data partition comprises a solid-state device drive.
10. The computerized-system of claim 9 , wherein the second data partition comprises another solid-state device drive.
