摘要： A computer-implemented method for determining a query execution plan based on transaction state may include determining that a first set of database values in a database table are in a committed transaction state and that a second set of database values in the database table are in an uncommitted transaction state. In response to the determining, the first set of database values may have a first set of statistics generated and the second set of database values may have a second set of statistics generated. The first and second set of statistics may be for use in determining a query execution plan.

摘要： Aspects of the present disclosure are directed towards managing computing resources. Managing computing resources can include initializing in a computer system, an application that corresponds to one or more commit signatures, each of the one or more commit signatures correspond to a transaction within the application and determining that a commit signature of one or more commit signatures is saved in a commit block (COB). Managing computing resources can include retrieving, from the COB, in response to determining that the commit signature is saved in the COB, a first set of resource data that corresponds to the commit signature, the first set of resource data contains information for resource usage that corresponds to the application and allocating resources accessible to the computer system based on the first set of resource data.

摘要： A computer-implemented method for reusing deleted database records includes, receiving, by a database manager executing within a computing device, a first query request to insert, into a database table, a first set of database records. The database manager identifies a first set of entries within a journal log bundle. The database manager also determines, in response to identifying a first set of entries, that there is a third set of deleted database records located on a same page as a second set of database records. The database manager also, in response to determining that there is a third set of deleted database records located on a same page as the second set of database records, inserts into the database table the first set of database records using the third set of deleted database records.

摘要： A program identifier, a limit identifier, a minimum value, and an increment value are stored to limit data. The limit identifier identifies a first variable used by the program. In response to storing a data value to a second variable, the stored limit identifier is found and a determination is made whether the stored limit identifier identifies the second variable. If the stored limit identifier identifies the second variable, a determination is made whether the data value is greater than the minimum value. If the data value is greater than the minimum value, the data value is stored to a log if an absolute value of the data value minus a most recently logged data value that was previously stored to the second variable is greater than the increment value. The execution of the program is halted or a user is notified in response to the storing to the log.

摘要： Systems and methods for providing automatic fork protection including determining that a transaction having fork protection was included in a first block that was appended to a blockchain, that a hash of the first block was validated, that a consensus decision was made by validator nodes approving the first block for addition to the blockchain, that a second block was appended to the blockchain after the first block, that the second block comprises a hash that is not based on the first block, that the first block was on a first fork and the second block was on a second fork, that the blockchain was resolved in favor of the second fork, and that the transaction failed as a result of the blockchain being resolved in favor of the second fork. The method including compensating a party that submitted the failed transaction based on the fork protection.

摘要： A structured query language (SQL) query is configured to present a selected portion of a result set to a user interface. The selected portion of the result set can be based on an offset criteria appended to the SQL query. The offset criteria determines a location of a first presented instance of the selected portion of the result set. The offset criteria is configured to determine the location of the first presented instance of the selected portion of the result set independent of a number of instances appearing between a first instance of the result set and the first presented instance of the selected portion of the result set.

摘要： Each of one or more commit cycles may be associated with a predicted number of updates. A statistics collection time for a database table can be determined by estimating a sum of predicted updates included in one or more commit cycles. Whether the estimated sum of predicted updates is greater than a first threshold may be determined. In addition, a progress point for a first one of the commit cycles can be determined. A time to collect statistics may be selected based on the progress point of the first commit cycle.

摘要： A first database management system (DBMS) running on first computer having a first set of computing resources determines that with respect to the first set of computing resources a first query access plan for executing a query satisfies a set of query optimization criteria. A determination is then made that with respect to a second set of computing resources the first query access plan fails a set of preliminary criteria. In response to this failure determination, a second query access plan for executing the query is generated. Prior to having a second DBMS running on a second computer having the second set of computing resources receive a request to execute the query, a determination is made that with respect to the second set of computing resources the second query access plan satisfies the set query optimization criteria.
