Batch Insertion: Accumulates inserts in a cache (vector) Flushes cache when reaching BATCH_SIZE Uses transactions to group inserts Reuses prepared statements Performance Optimizations: Transactions reduce disk I/O operations Prepared statements avoid SQL parsing overhead Memory reserve for vector prevents ...

We will change the script that creates our environment so we won’t create the index until the bulk insertion is complete. The new script will be: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 -- Create the database create database TestBatch on (name=data,filename=...

Or it can be manually set with proper values for order (Negative values used to skip conflict with existing ones in Db). Here single Id value itself doesn't matter, db will change it to next in sequence, what matters is their mutual relationship for sorting. Insertion order is implemented...
And it only does the translation between database/sql and the network. It is not an ORM framework. It does not help with batch insertion, but it provides what you need for it. You'd have to write the batch insertion query yourself, the driver will send that query to the database for...
but can still cause recompilations. Take, for example, a batch that contains a literal larger than 8 KB. Suppose that this batch creates a temporary table, and then inserts 20 rows in that table. The insertion of the seventh row will cause a recompilation, but because of the large litera...
