Properties

Property	Value
`es_uri`	URI for Elasticsearch Server. ex. `https://lumeo1.elastic-cloud.com:9243` ex. `https://user:[email protected]:9243`
`es_api_key`	Base10 encoded API key for your Elasticsearch server. Leave empty if you specify credentials in the URI. ex. `V2F2Zk1YNEJkS2lTUHFvc0aUQ==`
`es_index`	Name of the index to which metadata will be published. This index will be created if it does not exist already. ex. `lumeometa`
`trigger`	If set, the metadata is only published when this trigger condition evaluates to True, subject to the minimum interval as specified below. The trigger expression must be a valid Dot-notation expression that operates on Pipeline Metadata and evaluates to `True` or `False`. See details here. ex. `nodes.annotate_line_counter1.lines.line1.total_objects_crossed_delta > 0
`interval`	Minimum time, in seconds, between consecutive Google Sheets publishing actions. If a trigger is not specified, the metadata will be published on the spreadsheet at this interval. ex. `60`
`schedule_publishing`	If set, ignores the Min Interval property and schedules publishing at a synchronized time. Options: Every Day Every Hour Every 30 minutes Every 15 minutes
`batch`	If true, collects metadata between the publishing intervals, and sends it as a batch. Else sends just a specific frame's metadata, discarding the metadata of the frames between each publishing interval. ex. `true` / `false`
`snapshot_type`	If not None, send snapshot as a base64 encoded jpeg to Elasticsearch. Warning: Significantly increases your ES storage consumption. Options: None (null) `small` : Max 320px width `medium` : Max 640px width
`use_stream_clock`	If true, reports timestamps from the stream to Elasticsearch instead of using clock time. Enable to report correct time information when processing files, since they are typically processed faster than real time. ex. `true` / `false`

Metadata

This node does not add any new metadata to the frame.
