Feed: Blog. Author: Ron Huizenga; ER/Studio Data Architect contains extensive metadata for all constructs utilized in the models and data dictionaries, whether used in logical modeling, physical modeling, or both. This includes names, descriptions, comments, datatypes, lengths and a myriad of additional properties. However, organizations often wish to define and create additional metadata to further define and classify model objects. This can be for a variety of reasons, but often it is to enable data governance. ER/Studio handles this through a construct called attachments. Attachments can be used to define additional properties for virtually any construct within data models and ... Read More

Like most analytics platforms it’s built on a column-oriented storage basis and unlike many alternatives is completely open source. It’s also exceedingly fast, even on relatively modest platforms.Clickhouse does have some differences from some other environments, for example, data inserted cannot easily be updated, and it supports a number of different storage and table engine formats that are used to store and index the information. So how do we get into that from our MySQL transactional ... Read More

Feed: Planet PostgreSQL. This blog is about my work on the Postgres open source database, and is published on Planet PostgreSQL. PgLife allows monitoring of all Postgres community activity. Micro-Optimizations Friday, December 14, 2018 This email thread discusses the tradeoffs of adding optimization improvements that affect only a small percentage of queries, i.e., micro-optimizations. The big sticking point is that we don't know if the time required to check for these optimizations is worth it. For short-running queries, it probably isn't, but for long-running queries, it probably is. The problem is that we don't know the final cost of the ... Read More

Feed: Planet PostgreSQL. PREVIOUS POST PostgreSQL streaming physical replication with slots simplifies setup and maintenance procedures. Usually, you should estimate disk usage for the Write Ahead Log (WAL) and provide appropriate limitation to the number of segments and setup of the WAL archive procedure. In this article, you will see how to use replication with slots and understand what problems it could solve. Introduction PostgreSQL physical replication is based on WAL. Th Write Ahead Log contains all database changes, saved in 16MB segment files. Normally postgres tries to keep segments between checkpoints. So with default settings, just 1GB of WAL segment files is ... Read More
