WAL buffers, and CLOG buffers. The main purpose of a buffer is to store the data. Similarly, we have a shared buffer in PostgreSQL, which stores data on the server. A shared buffer is faster to read or write data than other buffers. Database servers must need buffers...
Learn how to find slow queries in PostgreSQL using logs and metrics. Tutorial on how to check for and fix performance issues to speed up your database.
The PostgreSQL.conf file contains a parameter known as “shared_buffers.” These buffers are referred to as “shared” because they are accessed by all background servers. The shared buffer is responsible for allocating memory to cache data, providing several key advantages such as enhanced system...
Large numbers of fsyncs by client backends could indicate misconfiguration of shared buffers or of the checkpointer. The stats do not differentiate between data which had to be fetched from disk and that which already resided in the kernel page cache. Allow vacuum/analyze to specify buffer ...

Well the way PostgreSQL does batches having a batch size this large does not make sense. Not sure what "We can use MAX_ALLOWED_PACKET parameter which is defined in MySQL server in the server side." has to do with anything? Sorry, something went wrong. ...
I used MySQL 5.1.41 for my tests increasing buffer pool to 1G and log file size to 128M so all data is comfortably in memory. I ranged number of partitions from 1 to 1000 and loaded the table with 1000000 of sequential values from 1 to 1million (the C column was set same as ID ...
order to use disk space and a small amount of memory at the same time without a huge disk I/O penalty. The idea is to load in memory only the parts that are currently processed. This is important when you need to sort a multi-gigabyte table with only a memory buffer of 100 ...
