Re: Reg: Help to understand the source code

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)
