Hi, I'm performing an intensive write and read operations using PHT.
Everything works fine but after few minutes I'm getting some
exceptions. (listed below) . Pht database stops at 25MB.
And here are my methods, which are executed:
--------------------
using (var table = new PersistentHashTable(_dataBase))
{
table.Initialize();
table.Batch(actions =>
{
foreach (var item in records)
{
actions.Put(new PutRequest
{
Key = item.FetchedUri,
Bytes = new byte[] { 1 },
ExpiresAt =
item.PublishDate.AddMonths(2),
ParentVersions = new
ValueVersion[0],
OptimisticConcurrency =
false,
IsReadOnly = true
});
}
actions.Commit();
});
}
--------------------
using (var table = new PersistentHashTable(_dataBase))
{
table.Initialize();
table.Batch(actions =>
{
result = actions.Get(new GetRequest { Key =
fetchedUri }).Length == 1;
});
}
--------------------
