Abstract: Described is a system (and method) for efficiently distributing connections to service instances that stream multi-tenant data. The system may efficiently distribute requests to stream data by grouping (or “binning”) requests for a particular topic stream to a service instance that is elected a leader for that topic. The election of the leaders may be coordinated by the service instances themselves. The service instances may initiate the redistribution of the requests to the elected leaders by updating a cookie of a client to identify the service instance determined to be the elected leader of the requested topic stream. This cookie may be respected by a load balancer when directing clients to particular service instances. For example, the load balancer may be configured to implement session persistence (or session stickiness, session affinity, etc.) between the client and service instances based on the cookie.

Abstract: Methods, systems, and devices for data migration are described. In a system, databases may utilize different database-specific encryption keys for storage security. In some cases, the system may migrate data from a source database to a target database. To securely migrate the data, the source database may generate a temporary encryption key. The source database may decrypt the data using its database-specific key and may re-encrypt the data using this temporary encryption key. Additionally, the source database may wrap the temporary key with a public key corresponding to the target database. The source database may send the re-encrypted data and the wrapped temporary key to the target database. The target database may unwrap the temporary key using a private key associated with the public key and may decrypt the data using the temporary key before re-encrypting the data with its database-specific key for data storage.

Abstract: An entries array having a pre-selected number of initially empty buckets and structured as a circular array is maintained. Each of the pre-selected number of entries in the entries array has a corresponding index value. A chaining array having the pre-selected number of buckets and structured as a circular array is also maintained. Each of the pre-selected number of entries in the chaining array has the same corresponding index value as the corresponding bucket in the entries array. A hash operation is performed on data to be stored to determine a hash value corresponding to the data. The data is stored in a bucket in the entries array corresponding to the hash value as an unmovable head-of-chain entry, and moving previous data, if any, stored in the entries array corresponding to the hash value if the previous data has a different hash value. The data is stored in another bucket in the entries array if the bucket in the entries array corresponding to the hash value is occupied by a head-of-chain entry.

Abstract: Systems, devices, and techniques are disclosed for identification of records for post-cloning tenant identifier translation. Records may be received from a database system executing a database executor at a computing device executing a database application. The database application may identify, from among the records, records that include a record header that includes a bit indicating that an encoded value of a tenant identifier is stored in the record in a column of the record that is not a tenant identifier column. The database application may generate an index based on the records identified by the database application. The database application may access the records using the index and replace the encoded value of the tenant identifier stored in columns of the records with an encoded new value of a tenant identifier.

Abstract: Systems and techniques for utilizing resource aware queues and/or service sharing in a multi-server environment. According to an example, an application server employs a traffic light metaphor to represent a utilization level of resources of the application server by associating a traffic light with each resource. A mapping is maintained that associates service requests with corresponding sets of affected traffic lights. A deferred queue is maintained for each traffic light to facilitate throttling of service requests directed to the application server that involve a resource that is under pressure. Responsive to receiving a service request directed to the application server, the service request is added directly or indirectly to one of multiple queues maintained in front of the application server based on a priority associated with the service request. Service requests are serviced from the queues in accordance with a priority associated with the queues.

Abstract: Provided are systems and methods for verifying, in a database system, that a modification request to events data is completed. The method marks a modification request as verifying and implements a search strategy to search for unmodified events data (the stragglers) in the least expensive query scope first and then keep expanding the scope of the query until at least one unmodified events data is found (a straggler), which is marked as a fail. This strategy includes (i) beginning at a lowest scope search, (ii) searching a (database first: continuing to expand the search scope as high as it can go without a fail, and (iii) only when it's finished searching the database without a fail, searching a search engine in the same way. When the searches are done, and no fails have been marked, the method marks the request as done.
