Description

This is a tuning parameter that can be used in HBase to improve performance as a trade-off to data loss. For large clusters, this is a very useful optimization that can be employed.

FIX
Added an optional config (Not available through default from the stack)

ams-site : timeline.metrics.tables.durability
Valid values it can take : SKIP_WAL / SYNC_WAL / ASYNC_WAL / FSYNC_WAL
