storage: change default engine type from RocksDB to Pebble #48145

  1. storage: change default engine type from RocksDB to Pebble 

    This flips the switch to use Pebble by default. This will cause all
tests which don't explicitly specify RocksDB (i.e. the vast majority) to
now use Pebble. One exception is certain roachtests which create store
directories using older versions of CRDB and then upgrade to the current
version. Those tests will continue to use RocksDB (for now) due to the
nature of how `--storage-engine=...` is "sticky" if not specified,
defaulting to the previously used storage engine.

Release note (general change): Change the default engine type for new
storage directories from RocksDB to Pebble. Existing stores will
continue to use the previously specified storage engine, and an explicit
specification (via `--storage-engine=...`) will override the default.
