def inferRegionsWithStats(sparkSession: SparkSession, fileStorage: FileStorageOps, basePath: Path, tableNames: Seq[String], includeHot: Boolean = true, skipRegionInfoCache: Boolean = false): Seq[AuditTableRegionInfo]

In one spark job scans all of the specified tables and infers stats about each region of the listed tables.

includeHot
if true, than hot regions will be included in the scan. By default is true. False is useful when reading production data from dev environments, as compactions will be happening in out of office hours, this helps to avoid reading data in an inconsistent state.

def openTables(sparkSession: SparkSession, fileStorage: FileStorageOps, basePath: Path, tableNames: Seq[String], includeHot: Boolean = true)(newRegionID: (AuditTableFile) ⇒ String): (Map[String, Try[AuditTableFile]], Seq[String])

Reads the state of the multiple Audit Tables.
Reads the state of the multiple Audit Tables. It will scan the state of regions of all specified tables in one go.
fileStorage
object that actually interacts with the physical storage
basePath
parent folder which contains folders with table names
tableNames
list of tables to open
includeHot
include hot regions in the table
newRegionID
function that generates region ids
returns
(Map[TABLE NAME, AuditTable], Seq[MISSING TABLES]) - audit table objects that exist and of table names that were not found under the basePath
def setRegions(audit: AuditTableFile, allRegions: Seq[AuditTableRegionInfo], appendedRegions: Option[Seq[AuditTableRegionInfo]]): AuditTableFile

Creates a copy of the table with new list of regions.
Creates a copy of the table with new list of regions.
audit
- Audit table with old regions
allRegions
- Complete set of current regions
appendedRegions
- Optional list of regions that have been appended. If given, only new regions are written to cache. If None the current cached region information is completely rewritten. If the case of any region deletes, this should be None.
