A database management system configured to perform a computer-implemented method is provided. The method involving configuring a first set of nodes to determine an instantaneous state of the database management system, generate system configuration data, and provide the system configuration data to a second set of nodes of the database management system, wherein the configuration data is replicated amongst the first set of nodes according to a consensus-based replication protocol so as to maintain the system configuration data. The method also involves configuring the second set of nodes to receive the system configuration data and implement a state machine that is arranged to modify a configuration of the second set of nodes according to the system configuration data, wherein the second set of nodes are arranged to replicate user data according to a non-consensus-based replication protocol. A non-transitory computer-readable storage medium comprising instructions for performing the computer-implemented method is provided.

High availability with consensus in database systems

Disclosed herein is a method of managing data in a database management system comprising a first, master storage, node and a second node for performing operations on data stored in the database. The method comprises configuring the second node to perform a set of steps. The second node is configured to write data indicative of one or more operations on data to a set of log files. The second node segments the set of log files into a set of log file chunks For each of the log file chunks, the second node may transmit data from the database associated with a log file chunk to the first node and thereafter transmit the log file chunk to the first node. The segmenting and transmitting of the set of log files and their associated data may be performed asynchronously to the updating of the set of log files.

Separation of storage and compute in database management systems

A non-transitory computer-readable medium is provided. The medium comprises a set of instructions, which, when executed by a processing system associated with a database or data warehouse, causes the processing system to retrieve data from a data source in accordance with a mapping between a first set of partitions and a second set of partitions, the first set of partitions being associated with the data source and the second set of partitions being associated with the database. The set of instructions, when executed by the processing system, further causes the processing system to load the retrieved data into the database. Retrieving the data and loading the retrieved data comprise a single logical unit of work. A database system and a method executed by a processing system associated with a database are also provided.
