Some time ago, at a restaurant near Boston, three Dynatrace colleagues dined and discussed the growing data challenge for enterprises. At its core, this challenge involves a rapid increase in the amount—and complexity—of data collected within a company. Existing observability and monitoring solutions have built-in limitations when it comes to storing, retaining, querying, and analyzing massive amounts of data.

If you’ve been a web developer for any reasonable amount of time, you’ve more likely than not come across an async snippet before. At its simplest, it looks a little like this: var script = document. createElement ( ' script ' ); script. src = ' [link] ' ; document. head. appendChild ( script ); Here, we…. create a element…. whose src attribute is [link] …. and append it to the.

Time-based grouping and aggregation are common in analyzing data using T-SQL—for example, grouping sales orders by year or by week and computing order counts per group. When you apply time-based grouping, you often group the data by expressions that manipulate date and time columns with functions such as YEAR, MONTH, and DATEPART. Such manipulation typically inhibits the optimizer’s ability to rely on index order.

One of the primary requisites to automate interactions with a WebElement in the DOM is that it should be visible and intractable.

The failure in the test automation script can be attributed to the presence of dynamic WebElements on the web page.

Lock Lifetimes. The examples so far in this series have all used repeatable read isolation to acquire shared locks on qualifying rows and hold them to the end of the transaction. This was convenient for the demos but repeatable read isolation isn’t common in everyday use. Locking optimizations. When SQL Server reads data under locking read committed isolation (the default for non-cloud offerings) and chooses row-level locking granularity, it normally only locks one row at a time.

Introduction. When thinking of security and quantum computers, many people may automatically think of using quantum computers for attacks on classical computers, by use of the Grover’s and Shor’s algorithms running on the quantum computers to break a number of existing cryptographic algorithms running on classical computers. Or, terms security and quantum computers are often associated with Quantum Key Distribution (QKD) or Quantum True Random Number (QTRNG) technologies.

Log data provides a unique source of truth for debugging applications, optimizing infrastructure, and investigating security incidents. To further enrich log data for automated observability, it’s necessary to dynamically tie logs to distributed traces on the code level, user sessions in the app front-end, and the topology of your IT landscape. This contextualization of log data enables AI-powered problem detection and root cause analysis at scale.

Parallelism. In part one of this series , I explained how the lock manager maintains a count of held locks per transaction , and individual access methods keep a separate lock count per HoBt for each plan operator performing data access. Parallelism adds an extra layer of complexity because both lock counts are maintained per thread. There are two underlying reasons for this: Each additional parallel worker thread operates inside a nested sub-transaction with the original transaction as its pare

Witness Server and Witness Directory are the most critical components of the Database Availability Group (DAG). DAG requires Witness Server or File Share Witness (FSW) and Directory to maintain the Quorum. In case of Witness Server failure, the Quorum is no longer maintained, leading to inconsistent DAG. In addition, the cluster may no longer respond or work, leading to downtimes if a disaster strikes.
