[jira] [Created] (SPARK-34062) Call updateTableStats() from
AlterTableAddPartitionCommand
Maxim Gekk created SPARK-34062:
----------------------------------
Summary: Call updateTableStats() from AlterTableAddPartitionCommand
Key: SPARK-34062
URL: https://issues.apache.org/jira/browse/SPARK-34062
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: Maxim Gekk
AlterTableAddPartitionCommand.run does almost the same as `CommandUtils.updateTableStats` while updating table stats. The code:
{code:scala}
if (table.stats.nonEmpty) {
if (sparkSession.sessionState.conf.autoSizeUpdateEnabled) {
val addedSize = CommandUtils.calculateMultipleLocationSizes(sparkSession, table.identifier,
parts.map(_.storage.locationUri)).sum
if (addedSize > 0) {
val newStats = CatalogStatistics(sizeInBytes = table.stats.get.sizeInBytes + addedSize)
catalog.alterTableStats(table.identifier, Some(newStats))
}
} else {
catalog.alterTableStats(table.identifier, None)
}
}
{code}
can be replaced by:
{code:scala}
CommandUtils.updateTableStats()
{code}
