Hi, Rohit, RocksDB TTL is best-effort: https://github.com/facebook/rocksdb/wiki/Time-to-Live. And the expired records are removed during compaction.
I wonder in your test case whether the compaction has ever happened. How long did you wait to see whether records are gone or not? -Yi On Thu, Mar 10, 2016 at 9:50 PM, Rohit Bansal <bansalrohi...@gmail.com> wrote: > Navina, > > Please find my configurations file below - > > # Licensed to the Apache Software Foundation (ASF) under one > # or more contributor license agreements.
