Smallrye nessie version store persist

Property	Default Value	Type	Description
`nessie.version.store.persist.repository-id`	(empty)	`String`	Nessie repository ID (optional) that identifies a particular Nessie storage repository. When remote (shared) database is used, multiple Nessie repositories may co-exist in the same database (and in the same schema). In that case this configuration parameter can be used to distinguish those repositories.
`nessie.version.store.persist.commit-retries`	`2147483647`	`int`	maximum retries for CAS-like operations. Used when committing to Nessie, when the HEAD (or tip) of a branch changed during the commit, this value defines the maximum number of retries. Default means unlimited. See: #retryMaxSleepMillis()
`nessie.version.store.persist.commit-timeout-millis`	`5000`	`long`	Timeout for CAS-like operations in milliseconds. See: #retryMaxSleepMillis()
`nessie.version.store.persist.retry-initial-sleep-millis-lower`	`5`	`long`	When the commit logic has to retry an operation due to a concurrent, conflicting update to the database state, usually a concurrent change to a branch HEAD, this parameter defines the initial lower bound of the exponential backoff. See: #retryMaxSleepMillis()
`nessie.version.store.persist.retry-initial-sleep-millis-upper`	`25`	`long`	When the commit logic has to retry an operation due to a concurrent, conflicting update to the database state, usually a concurrent change to a branch HEAD, this parameter defines the initial upper bound of the exponential backoff. See: #retryMaxSleepMillis()
`nessie.version.store.persist.retry-max-sleep-millis`	`250`	`long`	When the commit logic has to retry an operation due to a concurrent, conflicting update to the database state, usually a concurrent change to a branch HEAD, this parameter defines the maximum sleep time. Each retry doubles the lower and upper bounds of the random sleep time, unless the doubled upper bound would exceed the value of this configuration property. See: #retryInitialSleepMillisUpper()
`nessie.version.store.persist.parents-per-commit`	`20`	`int`	Number of parent-commit-hashes stored in each commit. This is used to allow bulk-fetches when accessing the commit log.
`nessie.version.store.persist.max-serialized-index-size`	`204800`	`int`	The maximum allowed serialized size of the content index structure in a reference index segment. This value is used to determine, when elements in a reference index segment need to be split. Note: this value must be smaller than a database’s hard item/row size limit.
`nessie.version.store.persist.max-incremental-index-size`	`51200`	`int`	The maximum allowed serialized size of the content index structure in a Nessie commit, called incremental index. This value is used to determine, when elements in an incremental index, which were kept from previous commits, need to be pushed to a new or updated reference index. Note: this value must be smaller than a database’s hard item/row size limit.
`nessie.version.store.persist.max-reference-stripes-per-commit`	`50`	`int`	Maximum number of referenced index objects stored inside commit objects. If the external reference index for this commit consists of up to this amount of stripes, the references to the stripes will be stored inside the commit object. If there are more than this amount of stripes, an external index segment will be created instead.
`nessie.version.store.persist.assumed-wall-clock-drift-micros`	`5000000`	`long`	Assumed wall-clock drift between multiple Nessie instances in microseconds.
`nessie.version.store.persist.ref-previous-head-count`	`20`	`int`	Named references keep a history of up to this amount of previous HEAD pointers, and up to the configured age.
`nessie.version.store.persist.ref-previous-head-time-span-seconds`	`300`	`long`	Named references keep a history of previous HEAD pointers with this age in seconds, and up to the configured amount.
`nessie.version.store.persist.cache-capacity-mb`		`int`	Fixed amount of heap used to cache objects, set to 0 to disable the cache entirely. Must not be used with fractional cache sizing. See description for `cache-capacity-fraction-of-heap` for the default value.
`nessie.version.store.persist.cache-capacity-fraction-min-size-mb`		`int`	When using fractional cache sizing, this amount in MB is the minimum cache size.
`nessie.version.store.persist.cache-capacity-fraction-of-heap`		`double`	Fraction of Java’s max heap size to use for cache objects, set to 0 to disable. Must not be used with fixed cache sizing. If neither this value nor a fixed size is configured, a default of .7 (70%) is assumed.
`nessie.version.store.persist.cache-capacity-fraction-adjust-mb`		`int`	When using fractional cache sizing, this amount in MB of the heap will always be “kept free” when calculating the cache size.
`nessie.version.store.persist.reference-cache-ttl`		`Duration`	Defines the duration how long references shall be kept in the cache. Enables reference-caching, if configured with a positive duration value, defaults to not cache references. If reference caching is enabled, it is highly recommended to also enable negative reference caching. This is an experimental feature, currently only for single Nessie node deployments! If in doubt, leave this un-configured!
`nessie.version.store.persist.reference-cache-negative-ttl`		`Duration`	Defines the duration how long sentinels for non-existing references shall be kept in the cache (negative reference caching). Enabled, if configured with a positive duration value, default is not enabled. If reference caching is enabled, it is highly recommended to also enable negative reference caching. This is an experimental feature, currently only for single Nessie node deployments! If in doubt, leave this un-configured!
