- all tests green on RoaringTx
- RoaringTx on by default
- blueGreenTx testing framework available for A-vs-B comparison
of Tx implementations
- flag -tx added to server command line but not wired to
change NewIndex() selection yet.
- 918 green tests, 14 tests red on BadgerTx.
A full list of the 14 red tests on BadgerTx follows.
Note that these red tests represent not defects in BadgerDB
or BadgerTx but rather failures of the pre-existing pilosa infrastructure to yet
be fully adapted from files to using a transactional storage engine.
As such these are tests that RBF should not be expected to
pass yet either.
Fixing the pilosa infrastructure to allow these tests
to go green under Badger is the next and highest priority
order of business, but RBF can get much testing benefit
from the 918 green tests we do have, and hence we merge
as much as we have today.
The 14 red tests when NewIndex() is set to use
BadgerTx are as follows. Note in particular
that pilosa cluster resizing is not working yet under a
transactional store.
