The history of Grail: Why you need a data lakehouse

Dynatrace

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.

Speeding Up Async Snippets

CSS Wizardry

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.

DATE_BUCKET and DATETRUNC Improve Optimization of Time-Based Grouping

SQL Performance

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.

The Lock Escalation Threshold – Part 3

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.

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.
