Abstract: A management server is configured to detect that a request to add a new column of data to a storage server has been received, determine that the new column of data is a duplicate of a column of data already stored at the storage server by comparing metadata describing the new column and the metadata describing the tables stored at the storage server, and, in response to the new column of data being the duplicate of the column of data already stored in the storage server, generate, by an interceptor application of the management server, an indication that the new column of data is already stored at the storage server.

Abstract: A system for identifying similarities between tables and databases stored in a storage server comprises the storage server and a management server. The storage server comprises a first database configured to store a plurality of first database tables, and a second database configured to store a plurality of second database tables. The management server is configured to store a storage index indicating metadata describing a plurality of tables stored at the storage server, wherein the metadata indicates a column name of a column in each of the tables, determine a table similarity score, a database similarity score, and access data, and transmit an instruction to the storage server to delete data stored in at least one of the first database or the source table to eliminate redundancies at the storage server.

Abstract: A publish-subscribe messaging method including: generating a modified first publication message by modifying a first publication message to include a reply-to property that directs a recipient device to acknowledge, to an acknowledgment queue, receipt of the first publication message; publishing the modified first publication message to (i) the acknowledgment queue and (ii) a consumer queue; responsive to the modified first publication message being consumed by one or more subscribers and/or a first timeout for the modified first publication message expiring, deleting the modified first publication message from the consumer queue; and responsive to the acknowledgment queue receiving an acknowledgment for the modified first publication message and/or a second timeout for the modified first publication message expiring, deleting the modified first publication message from the acknowledgment queue.
