Hello Adrian, Thank you for the quick reply. This link is indeed helpful. This link explains how is a query processed. I am aware of how the query processing happens.
In addition, I am looking for how the data processed, when data is inserted/modified, does the new data gets written to shared buffer -> WAL -> disk ? I would like to see the code that does this. (For example, data written into shared_buffer, wal_buffer, wal_segments and then fsync) On Thu, Apr 23, 2020 at 10:49 AM Adrian Klaver <adrian.kla...@aklaver.com> wrote: > On 4/23/20 8:44 AM, Preethi S wrote: > > Hello, > > > > I am fairly new to postgres and I am trying to understand how the data > > is processed during the insert from buffer to the disk.
