There are several resources where locks can be placed, such as a row in a table or a lock on each row within an index.

Lock resources refer to the places where SQL can place locks, and lock modes refer to the locks that can be placed on resources so they can be accessed by concurrent tasks and transactions.

Locking: In SQL, there are lock resources and lock modes.

A third common wait type is the WRITELOG wait, which is related to the SQL session writing the contents of the cache of a log to the disk where the log is stored. Two common wait types are latch wait types, such as PAGEIOLATCH_EX, which refers to a wait that happens when a task is waiting on a latch for an I/O request type of buffer, and CXPACKET wait types, a typical problem related to high server CPU usage due to poorly-written parallel queries (queries designed to run concurrently). While SQL is executing one or more queries or pulling resources, a certain amount of time must be spent both scanning the storage and data and performing the calculation or task at hand.

Wait States or Queue States: A period of waiting that comes after executing queries or loading resources related to particular tasks.

Let’s look at some definitions before we begin:

This article will explain how to find and address multiple SQL performance challenges. You might be dealing with slow-moving or poorly-written queries, inefficient subqueries, indexes with tons of writes to them but little or no reads, or different CPU and memory issues. Google Cloud also today brought Vertex AI Workbench, a tool for managing the entire lifecycle of a data science project, out of beta and into general availability, and launched Connected Sheets for Looker, as well as the ability to access Looker data models in its Data Studio BI tool.There’s a good chance you’ve come across various performance challenges while writing queries and working within SQL if you use it on a regular basis. “This ensures customers always have access to the freshest data as they can easily replicate changes from Spanner to BigQuery for real-time analytics, trigger downstream application behavior using Pub/Sub, or store changes in Google Cloud Storage (GCS) for compliance,” explains Kazmaier. In addition to BigLake, Google also today announced that Spanner, its globally distributed SQL database, will soon get a new feature called “change streams.” With these, users can easily track any changes to a database in real time, be those inserts, updates or deletes. Our customers have made it clear they need help.” As an organization’s data gets more complex and proliferates across disparate data environments, silos emerge, creating increased risk and cost, especially when that data needs to be moved. “This data is increasingly distributed across many locations, including data warehouses, data lakes, and NoSQL stores.

“The volume of valuable data that organizations have to manage and analyze is growing at an incredible rate,” Google Cloud software engineer Justin Levandoski and product manager Gaurav Saxena explain in today’s announcement.

“ BigLake allows companies to unify their data warehouses and lakes to analyze data without worrying about the underlying storage format or system, which eliminates the need to duplicate or move data from a source and reduces cost and inefficiencies.” “ Managing data across disparate lakes and warehouses creates silos and increases risk and cost, especially when data needs to be moved,” explains Gerrit Kazmaier, VP and GM of Databases, Data Analytics and Business Intelligence at Google Cloud, notes in today’s announcement. Through BigLake, developers will get access to one uniform storage engine and the ability to query the underlying data stores through a single system without the need to move or duplicate data. This data, it’s worth noting, could sit in BigQuery or live on AWS S3 and Azure Data Lake Storage Gen2, too. The idea here, at its core, is to take Google’s experience with running and managing its BigQuery data warehouse and extend it to data lakes on Google Cloud Storage, combining the best of data lakes and warehouses into a single service that abstracts away the underlying storage formats and systems. At its Cloud Data Summit, Google today announced the preview launch of BigLake, a new data lake storage engine that makes it easier for enterprises to analyze the data in their data warehouses and data lakes.
