Timestamp format filter plugin for Embulk
A filter plugin for Embulk to change timesatmp format
Configuration
- columns: columns to retain (array of hash)
- name: name of column, must be a string column (required)
- from_format: specify the format of the input timestamp (array of strings, default is default_from_format)
- from_timezone: specify the timezone of the input timestamp (string, default is default_from_timezone)
- to_format: specify the format of the output timestamp (string, default is default_to_format)
- to_timezone: specify the timezone of the output timestamp (string, default is default_to_timezone)
- default_from_format: default timestamp format for the input timestamp columns (array of strings, default is
["%Y-%m-%d %H:%M:%S.%N %z"]
) - default_from_timezone: default timezone for the input timestamp columns (string, default is
UTC
) - default_to_format: default timestamp format for the output timestamp columns (string, default is
%Y-%m-%d %H:%M:%S.%N %z
) - default_to_timezone: default timezone for the output timestamp olumns (string, default is
UTC
) - stop_on_invalid_record: stop bulk load transaction if a invalid record is found (boolean, default is `false)
Example
Say example.jsonl is as follows (this is a typical format which Exporting BigQuery table outputs):
{"timestamp":"2015-07-12 15:00:00 UTC","record":{"timestamp":"2015-07-12 15:00:00 UTC"}}
{"timestamp":"2015-07-12 15:00:00.1 UTC","record":{"timestamp":"2015-07-12 15:00:00.1 UTC"}}
in:
type: file
path_prefix: example/example.jsonl
parser:
type: jsonl
columns:
- {name: timestamp, type: string}
- {name: record, type: json}
filters:
- type: timestamp_format
default_to_timezone: "Asia/Tokyo"
default_to_format: "%Y-%m-%d %H:%M:%S.%N"
columns:
- {name: timestamp, from_format: ["%Y-%m-%d %H:%M:%S.%N %z", "%Y-%m-%d %H:%M:%S %z"]}
- {name: record.timestamp, from_format: ["%Y-%m-%d %H:%M:%S.%N %z", "%Y-%m-%d %H:%M:%S %z"]}
type: stdout
Output will be as:
{"timestamp":"2015-07-13 00:00:00.0","record":{"timestamp":"2015-07-13 00:00:00.0}}
{"timestamp":"2015-07-13 00:00:00.1","record":{"timestamp":"2015-07-13 00:00:00.1}}
ToDo
- Currently, input must be a String column and output will be a String column. But, support Timestamp column (input / output)
- Write test
