Overview

A partition start record serves as a notification that the client should schedule the partitions to be queried. PartitionStartRecord returns information about one or more partitions.

Instance Attribute Summary

• #partition_tokens ⇒ Array<String>

  Unique partition identifiers to be used in queries.

• #record_sequence ⇒ String

  Record sequence numbers are unique and monotonically increasing (but not necessarily contiguous) for a specific timestamp across record types in the same partition.

• #start_timestamp ⇒ String

  Start timestamp at which the partitions should be queried to return change stream records with timestamps >= start_timestamp.

Instance Method Summary

• #initialize(**args) ⇒ PartitionStartRecord constructor

  A new instance of PartitionStartRecord.

• #update!(**args) ⇒ Object

  Update properties of this object.

Instance Attribute Details

#partition_tokens ⇒ Array<String>

Unique partition identifiers to be used in queries. Corresponds to the JSON property partitionTokens

# File 'lib/google/apis/spanner_v1/classes.rb', line 5212

def partition_tokens
  @partition_tokens
end

#record_sequence ⇒ String

Record sequence numbers are unique and monotonically increasing (but not necessarily contiguous) for a specific timestamp across record types in the same partition. To guarantee ordered processing, the reader should process records (of potentially different types) in record_sequence order for a specific timestamp in the same partition. Corresponds to the JSON property recordSequence

# File 'lib/google/apis/spanner_v1/classes.rb', line 5221

def record_sequence
  @record_sequence
end

#start_timestamp ⇒ String

Start timestamp at which the partitions should be queried to return change stream records with timestamps >= start_timestamp. DataChangeRecord. commit_timestamps, PartitionStartRecord.start_timestamps, PartitionEventRecord. commit_timestamps, and PartitionEndRecord.end_timestamps can have the same value in the same partition. Corresponds to the JSON property startTimestamp

# File 'lib/google/apis/spanner_v1/classes.rb', line 5230

def start_timestamp
  @start_timestamp
end
