示例1: UpdateAnimeSeriesContractsAndSave
private void UpdateAnimeSeriesContractsAndSave(ISessionWrapper session, IReadOnlyCollection<AnimeSeries> series)
{
_log.Info("Updating contracts for AnimeSeries");
// Update batches of AnimeSeries contracts in parallel. Each parallel branch requires it's own session since NHibernate sessions aren't thread safe.
// The reason we're doing this in parallel is because updating contacts does a reasonable amount of work (including LZ4 compression)
Parallel.ForEach(series.Batch(DefaultBatchSize), new ParallelOptions { MaxDegreeOfParallelism = 4 },
localInit: () => DatabaseFactory.SessionFactory.OpenStatelessSession(),
body: (seriesBatch, state, localSession) =>
{
AnimeSeries.BatchUpdateContracts(localSession.Wrap(), seriesBatch);
return localSession;
},
localFinally: localSession => { localSession.Dispose(); });
_animeSeriesRepo.UpdateBatch(session, series);
_log.Info("AnimeSeries contracts have been updated");
}示例2: UpdateAnimeGroupsAndTheirContracts
private void UpdateAnimeGroupsAndTheirContracts(ISessionWrapper session, IReadOnlyCollection<AnimeGroup> groups)
{
_log.Info("Updating statistics and contracts for AnimeGroups");
var allCreatedGroupUsers = new ConcurrentBag<List<AnimeGroup_User>>();
// Update batches of AnimeGroup contracts in parallel. Each parallel branch requires it's own session since NHibernate sessions aren't thread safe.
// The reason we're doing this in parallel is because updating contacts does a reasonable amount of work (including LZ4 compression)
Parallel.ForEach(groups.Batch(DefaultBatchSize), new ParallelOptions { MaxDegreeOfParallelism = 4 },
localInit: () => DatabaseFactory.SessionFactory.OpenStatelessSession(),
body: (groupBatch, state, localSession) =>
{
var createdGroupUsers = new List<AnimeGroup_User>(groupBatch.Length);
// We shouldn't need to keep track of updates to AnimeGroup_Users in the below call, because they should have all been deleted,
// therefore they should all be new
AnimeGroup.BatchUpdateStats(groupBatch, watchedStats: true, missingEpsStats: true, createdGroupUsers: createdGroupUsers);
allCreatedGroupUsers.Add(createdGroupUsers);
AnimeGroup.BatchUpdateContracts(localSession.Wrap(), groupBatch, updateStats: true);
return localSession;
},
localFinally: localSession => { localSession.Dispose(); });
_animeGroupRepo.UpdateBatch(session, groups);
_log.Info("AnimeGroup statistics and contracts have been updated");
_log.Info("Creating AnimeGroup_Users and updating plex/kodi contracts");
List<AnimeGroup_User> animeGroupUsers = allCreatedGroupUsers.SelectMany(groupUsers => groupUsers).ToList();
// Insert the AnimeGroup_Users so that they get assigned a primary key before we update plex/kodi contracts
_animeGroupUserRepo.InsertBatch(session, animeGroupUsers);
// We need to repopulate caches for AnimeGroup_User and AnimeGroup because we've updated/inserted them
// and they need to be up to date for the plex/kodi contract updating to work correctly
_animeGroupUserRepo.Populate(session, displayname: false);
_animeGroupRepo.Populate(session, displayname: false);
// NOTE: There are situations in which UpdatePlexKodiContracts will cause database database writes to occur, so we can't
// use Parallel.ForEach for the time being (If it was guaranteed to only read then we'd be ok)
foreach (AnimeGroup_User groupUser in animeGroupUsers)
{
groupUser.UpdatePlexKodiContracts(session);
}
_animeGroupUserRepo.UpdateBatch(session, animeGroupUsers);
_log.Info("AnimeGroup_Users have been created");
