01/31/2022, 11:48 AM(n * row / qds) * (latency * 3) // 1000
. The n is the row count, row is maximum byte size of the row, qds is the queryDataSize. Maximum value for qds was used (around 260KB). If the latency between ingestion server and db doubles, the time doubles. The fetchSize between 100 and 200 seemed to perform the best.
I wonder how a database management system anyways handles full table selects, assuming that a table is selected using a naive “SELECT * FROM table” without any lowerBound/upperBound partitioning on some column (e.g. WHERE partition_column BETWEEN 0 AND 10000). Does it just read the records in the heap file in the order they have been written? Paginated into fetchSize-sized pages? I suppose it has to somehow make sure that the different pages refer to the same version of the whole table - and storing the query result to memory is not realistic with whole tables.
I have read the Database Internals book by Alex Petrov (O’Reilly), but it was a lot to take in for a novice like me. Maybe I’ll need to read it again at some point.Daniel Spence
