Comment on SQLite performance tuning: concurrent reads, multiple GBs and 100k SELECTs/sparent

Comments

I am not sure if this works on my end:

  sqlite> PRAGMA journal_mode = delete;
  delete
  sqlite> PRAGMA journal_mode = wal2;
  delete
Does this mean wal2 is not available?

wal2 mode is not part of the main development branch of SQLite, you need to compile SQLite yourself from that branch. Same with BEGIN CONCURRENT [0]

Thank you!
