Initializing the Partitions of Inventory Tables
Function
Calculate the last modification time of each historical partition and write the time to the .hoodie_partition_metadata file in each partition in the format of lastUpdateTime=Last modification time. TTL determines whether a partition is aged based on the result of Current system time – Last modification time of the partition.
Syntax
call ttl_update_partitions(table => "[table]", path => "[path]", dryRun => [dryRun])
- If dryRun is true, the last modification time of each partition is printed, but is not written to the .hoodie_partition_metadata file.
- When dryRun is false, the last modification time of each partition is printed and written to the .hoodie_partition_metadata file.
