Label:Running out of disk space in the Pg_xlog directory is a fairly common Postgres problem. This important directory holds the WAL (Write Ahead Log) files. (WAL files contain a record of all changes made to the Database-see the link for more details). Because of the near write?only nature of this directory, it's often put on a separate disk. Fixing the out of space error is fairly easy:i would discuss a few remedies below. When the Pg_xlog directory

Introduction to CSTORE_FDWHTTPS://GITHUB.COM/CITUSDATA/CSTORE_FDW, this external table extension is developed by Citusdata Corporation, which uses the Orc_file format to store data in columns.　　Advantage 1: Because of the compression, so the storage on disk greatly reduced, compression ratio can reach 2-4 timesAdvantage 2: Data internal block storage, the block data for the max and Min value of the record, in the query can be a jump block queryAdvantage 3: In the query, not all the disk data

In this article, we will focus on another option, the open source database named PostgreSQL. Although MySQL is a fast, powerful, and fairly simple relational database management system, PostgreSQL is more comprehensive and sacrifices some speed for this complexity. If you are used to using interfaces that contain various icons and shortcuts, PostgreSQL is very suitable for you, although MySQL 4 provides similar functions. To clearly illustrate how to build PostgreSQL in this article, I use the

First, let's look at the definition: In text retrieval, Full-text Search is the technique of searching for a single or multiple documents (document) stored in a computer from a full-text database. Full-text search is different from a metadata based search or a search based on the original text in the database. --Wikipedia This definition introduces the concept of the document, which is important. When you search for data, you are looking for meaningful entities that you want to find, and th
