Abstract: A database system detects an operation to move a first database object from an in-memory store to a persistence store, wherein the first database object is in either a page-loadable or column-loadable format in the in-memory store, and wherein the first database object comprises a plurality of subcomponents. Each subcomponent of the first database object is examined separately from other subcomponents of the plurality of subcomponents. In response to determining that a first subcomponent of the plurality of subcomponents has a datatype and a compression type supported by a unified persistence format, the first subcomponent is stored in a unified persistence format in the persistence store. In response to determining that a second subcomponent of the plurality of subcomponents has either a datatype or a compression type which is not supported by the unified persistence format, the second subcomponent is stored in a serial persistence format in the persistence store.

Abstract: A method may include receiving a first transaction inserting a record into a database and a second transaction deleting the record from the database. A validity period for the record may be determined based on a first commit time at which the first transaction is committed and a second commit time at which the second transaction is committed. A current table and/or a history table of a system versioned table may be updated to include the record based on the validity period of the record. One or more temporal operations may be performed based on the system versioned table. For example, a time travel operation may be performed to retrieve, based on the system versioned table, one or more records that are valid at a given point in time. Related systems and computer program products are also provided.

Abstract: According to some embodiments, methods and systems may be associated with a cloud computing environment. A workload prediction framework may receive observed workload information associated with a database in the cloud computing environment (e.g., a DataBase as a Service (“DBaaS”)). Based on the observed workload information, a Statement Arrival Rate (“SAR”) prediction may be generated. In addition, a host variable assignment prediction may be generated based on the observed workload information. The workload prediction framework may then use the SAR prediction and the host variable assignment prediction to automatically create a workload prediction for the database. A physical database design advisor (e.g., a table partitioning advisor) may receive the workload prediction and, responsive to the workload prediction, automatically generate a recommended physical layout for the database (e.g., using a cost model, the current physical layout, and an objective function).

The modified current set of computer instructions are executed to generate a new monitoring status for output.

In each case the two clamping brackets are connectable at a first end by the clamp along a clamping axis, such that the clamp, when secured on the rail, engages under the rail foot of the rail. The clamping brackets each have, at a second end, a clamping region which is designed for force-locking arrangement on a rail web of the rail and/or on the rail-monitoring element. The clamping units, as separate elements, can be arranged on the rail to be mutually spaced along a longitudinal extent of the rail. The clamping brackets each have at least one curvature portion that is curved in a plane orthogonal with respect to the clamping axis.

Abstract: The technology relates to a method of producing synthesis gas comprising carbon monoxide (CO) and hydrogen (H2), wherein the synthesis gas is produced by a reduction reaction of a first flow comprising a carbon source and an excess of hydrogen in contact with an Oxy-flame. The hydrogen comes from a reducing stream, a first portion of which ends up in the first flow, and a second part of which is used to generate the Oxy-flame by combustion of the hydrogen in the presence of a second flow comprising oxygen (O2), the second flow coming from an oxidizing stream. The first flow and the second flow are at a distance from each other such that the Oxy-flame supports the reaction between the carbon source and the hydrogen. A reactor, which can have different configurations, is also proposed for implementing the method.

Abstract: A system and method for faster access for compressed time series data. A set of blocks are generated based on a table stored in a database of the data platform. The table stores data associated with multiple sources of data provided as consecutive values, each block containing index vectors having a range of the consecutive values. A block index is generated for each block having a field start vector representing a starting position of the block relative to the range of consecutive values, and a starting value vector representing a value of the block at the starting position. The field start vector of the block index is accessed to obtain the starting position of a field corresponding to a first block and to the range of the consecutive values of the first block. The starting value vector is then determined from the block index to determine an end and a length of the field of the first block.
