 | high.cardinality.threshold | 1000000  | It is a threshold to identify high cardinality of the columns.If the value of columns' cardinality > the configured value, then the columns are excluded from dictionary encoding. |
 | high.cardinality.row.count.percentage | 80 | Percentage to identify whether column cardinality is more than configured percent of total row count.Configuration value formula:Value of cardinality/ row number x 100 > configured value of high.cardinality.row.count.percentage. The value of the parameter must be larger than 0. |
 | carbon.cutOffTimestamp | 1970-01-01 05:30:00 | Sets the start date for calculating the timestamp. Java counts the number of milliseconds from start of "1970-01-01 00:00:00". This property is used to customize the start of position. For example "2000-01-01 00:00:00". The date must be in the form "carbon.timestamp.format". NOTE: The CarbonData supports data store up to 68 years from the cut-off time defined. For example, if the cut-off time is 1970-01-01 05:30:00, then the data can be stored up to 2038-01-01 05:30:00. |
