[sqlite] Efficient record insertion techniques?

Hi, I wrote a Real Time logging app that insert logs from various Unix machines in our lab into a sqlite Database. The insertions are not batched as of now. Maybe that itself is an optimization. 1) Should I use a transaction even for a single record? 2) I open the DB, insert the record and close

RE: [sqlite] Efficient record insertion techniques?

I'm no expert, but I hope the following are accurate. Regarding: 1) Should I use a transaction even for a single record? You already are, since your inserts automatically become one-line transactions. Re: 2) I open the DB, insert the record and close the DB for every record inserted. What if

[sqlite] Question about temp table performance

I have two versions of the same algorithm. The first operates directly on the main db table. The second operates on a temp table containing only the working set. The problem is that the second version is about 20x slower, 1.5 sec versus 30 sec. If the EXISTS line in the second version is
