LevelDB get 'stuck' in reorganizing keys.

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Generate about 100 Strings, like "00000" to "00999"
2. Generate around 200.000 (0 to 200k) numbers and concat them with the above 
like "0|00001", "1|00010", , ..., "199|00099", ..
3. Insert them into LevelDB

What is the expected output? What do you see instead?
Around 1.5M keys inserted, LevelDB starts to reorganize the files forever 
(watched around 15 minutes to no end). 

What version of the product are you using? On what operating system?
I'm using the Java LevelDB interface and MacOS X. Version 1.1.

Please provide any additional information below.
I know the keys are weird (to someone who don't know the business problem. 
LevelDB gives me something like this over the logger interface:

I even tried it with 1.5M random numbers, same thing. Any hint?

Just for clarification: It wasn't a pebkac problem, tried to delete the old 
comment, but it got already posted in the mailing list...

Do you have a standalone program that illustrates the problem?  Ideally in C++ 
since this project is not associated with the Java bindings.
