.db.checkpoint.throughput.limit

|Description
a|Limit the write throughput per second of the background checkpoint process. This setting is advisory. It is ignored in Neo4j Community Edition and is followed to best effort in Enterprise Edition. Limiting the write IO in this way leaves more bandwidth in the IO subsystem to service random-read IOs, which is important for the response time of queries when the database cannot fit entirely in memory. The only drawback of this setting is that longer checkpoint times may lead to slightly longer recovery times in case of a database or system crash. A lower number means lower IO pressure and, consequently, longer checkpoint times. Set this to null to disable the throughput limit and fallback to IOPS limit.
|Valid values
a|A byte size (valid multipliers are B, KiB, KB, K, kB, kb, k, MiB, MB, M, mB, mb, m, GiB, GB, G, gB, gb, g, TiB, TB, PiB, PB, EiB, EB) that is minimum 8.00KiB.
