MARCH 22, 2022

This series doesn’t dwell too long on the basics but concentrates on less well-known aspects likely to trip up even the most experienced database professionals. In this first part, after a quick introduction, I look at the effects of simple parameterization on the plan cache. ALTER DATABASE SCOPED CONFIGURATION. sp_configure.

JUNE 21, 2017

Today, I'm excited to announce the general availability of Amazon DynamoDB Accelerator (DAX) , a fully managed, highly available, in-memory cache that can speed up DynamoDB response times from milliseconds to microseconds, even at millions of requests per second. Adding caching when your app is already experiencing load is not easy.

Andreas Andreakis , Ioannis Papapanagiotou Overview Change-Data-Capture (CDC) allows capturing committed changes from a database in real-time and propagating those changes to downstream consumers [1][2]. In databases like MySQL and PostgreSQL, transaction logs are the source of CDC events. Designed with High Availability in mind.

Let’s look at some examples using the Stack Overflow 2010 database on SQL Server 2019 CU 14, with database compatibility set to 150. You must enable the query store feature for the database context where the statement is executed and the OPERATION_MODE must be set to READ_WRITE , allowing the query store to actively collect data.

As in previous parts, most code examples use the Stack Overflow 2010 database on SQL Server 2019 CU 16 with the following additional nonclustered index: CREATE INDEX [ IX dbo. Names of tables and columns haven’t been resolved to database objects yet, and no type information is available. Let’s look at the plan cache: SELECT.

For SQL Server 2012 and earlier, this means 5 extra bytes per row are included in the data size calculation: One byte for an internal bit flag, and four bytes for the uniquifier (used in the calculation even for unique indexes, which do not store a uniquifier ).

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively. low-end Androids have finally caught up to the iPhone 5 from 2012. The Moto G4 , for example.

Before we dive into the differences between MariaDB and MySQL, we will provide a thorough examination of each relational database management system (RDBMS). While originally designed to be a drop-in replacement for MySQL, it evolved into its own distinct database management system and is now maintained and supported by the MariaDB Foundation.

The following chart shows the same 1TB database testing. Use SQL Server Management Studio (SSMS) or your favorite query editor to connect to a SQL Server 2012 or 2014 instance. Note: You may need to execute the dbcc a second time so buffer cache is hot, eliminating I/O sub-system variants. MultiObjectScanner = Older design.

This made it easier for database professionals to make the case for a hardware upgrade, and made the typical upgrade more worthwhile. They will also have up to 256MB of L3 cache per processor.
