BatchReadPolicy.readTouchTtlPercent Field

Determine how record TTL (time to live) is affected on reads. When enabled, the server can efficiently operate as a read-based LRU cache where the least recently used records are expired. The value is expressed as a percentage of the TTL sent on the most recent write such that a read within this interval of the record’s end of life will generate a touch.

For example, if the most recent write had a TTL of 10 hours and read_touch_ttl_percent is set to 80, the next read within 8 hours of the record's end of life (equivalent to 2 hours after the most recent write) will result in a touch, resetting the TTL to another 10 hours.

Values:

• 0 : Use server config default-read-touch-ttl-pct for the record's namespace/set.
• -1 : Do not reset record TTL on reads.
• 1 - 100 : Reset record TTL on reads when within this percentage of the most recent write TTL.

Default: 0
