| 24 | * SYNOPSIS |
| 25 | * This file implements supporting threads for the secondary index implementation. |
| 26 | * Currently following two main threads are implemented here |
| 27 | * |
| 28 | * - Secondary index gc thread which walks sweeps through secondary indexes |
| 29 | * and cleanup the stale entries by looking up digest in the primary index. |
| 30 | * |
| 31 | * - Secondary index thread which cleans up secondary index entry for a particular |
| 32 | * partitions |
