 ** storageSeriesIdSetCacheSize **   <a name="tsinfluxdb-Type-InfluxDBv2Parameters-storageSeriesIdSetCacheSize"></a>
Size of the internal cache used in the TSI index to store previously calculated series results. Cached results are returned quickly rather than needing to be recalculated when a subsequent query with the same tag key/value predicate is executed. Setting this value to 0 will disable the cache and may decrease query performance.

Valid Range: Minimum value of 0. Maximum value of 1000000000000.  
Required: No

 ** storageWalMaxConcurrentWrites **   <a name="tsinfluxdb-Type-InfluxDBv2Parameters-storageWalMaxConcurrentWrites"></a>

Required: No

 ** storageWalMaxWriteDelay **   <a name="tsinfluxdb-Type-InfluxDBv2Parameters-storageWalMaxWriteDelay"></a>

Type: [Duration](API_Duration.md) object  
Required: No

Valid Values: `log | jaeger | disabled`   
Required: No

 ** uiDisabled **   <a name="tsinfluxdb-Type-InfluxDBv2Parameters-uiDisabled"></a>
