Java implementation of a Write Ahead Log.
This is a working implementation of a Write Ahead Log. It's purpose is to illustrate how this technique works.
It's extensively explained in this blog post.
| Version | Github Tag | Commit tree | Explanation |
|---|---|---|---|
| 0.1 | 0.1 | Commit Tree | Basic and trivial usage of the WAL. |
| 0.2 | 0.2 | Commit Tree | WAL writes to files and the garbage collector deletes them after the data has been comitted. |
| 0.3 | 0.3 | Commit Tree | Full implementation with data recovery |
This is, at the time of writing a toy project that implements some workarounds in order to implement the basic technique.
This implementation is:
- Using a trivial method to write to files.
- The files are text based for debugging and illustration purposes.
- The data is not serialised in any binary format.
