Abstract: Methods and systems for improving data store performance are provided. In one aspect, a method includes creating a target data definition for a target fact table; determining a source data definition of a source table; receiving at least one source record of the source table; mapping, in response to determining the source attributes of the at least one source record include at least one source attribute that corresponds to the at least one target attribute, the at least one source attribute to the at least one target attribute of the target record; and processing, in response to determining the source attributes of the at least one source record include at least one unmapped source attribute that does not correspond to the at least one target attribute, the at least one unmapped source attribute into an unmapped attributes store of the aggregate attribute.

Abstract: Methods and systems for synchronizing distributed databases are provided. In one aspect, a method includes transmitting a request to determine a schema of a first database and updating a metadata store with the schema. The method includes generating at least one database query. The method includes, responsive to the database query, selectively determining a data block size for a second database; segmenting a data source stored in the second database into sink data blocks; processing the data source into sink hashes; and transmitting, to an agent, at least one selected sink hash, wherein the agent transmits instructions to segment a table associated with the first database into source data blocks; process the table into source hashes; and generate, in response to a determination that the at least one selected sink hash differs from a corresponding source hash, query results. The method includes updating the data source with the query results.
