I am prototyping an application to store data in redis using
StackExhange.Redis client. I am using Protobuf for serializing my objects
and storing them as key/value pair in redis. When reading 20K keys using
pipeline (splitting keys in batches of 5000), I observe deserialization
times in 60-300 ms for a batch of say 5000 objects. Serialization code is
using protobuf-net library version. Deserialization code is using
protobuf-net 2.4.0.0.
Is there anyway I can speed up desrialization time since this will impact
my api performance.
The object I am trying to desrialize is not too complex.
[ProtoContract]
public struct MyObject
{
[ProtoMember(1)]
public int Key { get; set; }
[ProtoMember(2)]
public byte Attr1 { get; set; }
[ProtoMember(3)]
public bool IsUsed { get; set; }
[ProtoMember(4)]
public byte Attr2 { get; set; }
[ProtoMember(5)]
public SubObj[] SubObjects { get; set; }
public static MyObject Null
{
get
{
return default(MyObject);
}
}
public bool IsNull
{
get { return Attr1 == default(byte) && SubObjects == null; }
}
}
[ProtoContract]
public class SubObj
{
[ProtoMember(1)]
public int StartOffset { get; set; }
[ProtoMember(2)]
public int EndOffset { get; set; }
[ProtoMember(3)]
public byte Attr1 { get; set; }
[ProtoMember(4)]
public byte Attr2 { get; set; }
[ProtoMember(5)]
public bool IsUsed { get; set; }
public static SubObj Null
{
get
{
return default(SubObj);
}
}
public bool IsNull
{
get { return Attr1 == default(byte); }
}
}
Here're some sample timings using StopWatch:
Time to desrialize 5000 keys from redis:134
Time to desrialize 5000 keys from redis:147
Time to desrialize 5000 keys from redis:160
Time to desrialize 5000 keys from redis:65
Time to desrialize 5000 keys from redis:67
Time to desrialize 5000 keys from redis:242
Time to desrialize 5000 keys from redis:371
Time to desrialize 5000 keys from redis:190
Thanks,
