error: src refspec master does not match any.

When I executed the following command, I got an error.

#] git push origin env-properites
  error: src refspec env-properites does not match any.
  error: failed to push some refs to 'http://localhost/mygit/firsttest.git'

I can solve this problem by doing as here is written. It is easy!
Just modify unnecessary file like .gitignore.
And add & commit.
Run the above command again.

You can see the following message.

com.aerospike.client.AerospikeException: Error Code 13: Record too big

Recently I am trying to verify Aerospike can satisfy our requirements -
1. Persistent Cache for images
2. Time To Live(TTL)
3. Eviction
4. Remove all of related data by a key
5. Scale Out easily

I am testing it with YCSB to check performance. When I tried 256KB data size test, YCSB just stopped. As you know, YCSB is not kind. It doesn't show me any error message. So I ran the following code.

You can find out how to use Aerospike client here.

What? I already ran same test case on AWS and had no problem. They say "The size of the object or record is exceeding the limit, currently at 1MB". I just ran 256KB and 456KB. Something is wrong. I tried applying several data size files to find out MAX_SIZE. MAX_SIZE was 128KB. Finally I got a hint to solve this problem.

I am using data file because server was already configured RAID 10 with 4 SSDs and I did not want to go far far our data center. :) Anyway the reason was [write-block-size]. It makes limitation on using data file. When I use raw device([device]), I had no problem. I removed it and could run my test case.

You know what?  The max size of our images is 10MB. orz...
