Combinators

A computer program product for organizing data in a database system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:

• identifying, utilizing the processor, data to be stored in one or more tables on a bucket,
• where the bucket is an allocation of a partitioned storage in a node of one or more nodes of a swarm database, the bucket having at least one replica, and where no two identical bucket replicas reside on a single node;
• assigning, utilizing the processor, an identifier and a data storage hierarchical level to the data;
• mapping, utilizing the processor, the data to an index and storing the data in accordance with the index and the data storage hierarchical level, the storing including writing the data to a row in one of the one or more tables on the bucket and recording a write operation into a transaction log of the node;
• receiving, utilizing the processor, a plurality of write operations;
• and
• combining, utilizing the processor, a plurality of write tasks of the bucket for a predetermined time period.

A system, comprising:

• a processor and logic integrated with and/or executable by the processor, the logic being configured to:
• identify data to be stored in one or more tables on a bucket, where the bucket is an allocation of a partitioned storage in a node of one or more nodes of a swarm database, the bucket having at least one replica, and where no two identical bucket replicas reside on a single node;
• assign an identifier and a data storage hierarchical level to the data;
• map the data to an index and storing the data in accordance with the index and the data storage hierarchical level, the storing including writing the data to a row in one of the one or more tables on the bucket and recording a write operation into a transaction log of the node;
• receive a plurality of write operations;
• and
• combine a plurality of write tasks of the bucket for a predetermined time period.
