Fields
name

string

Output only. The name of the session. This is always system-assigned.

labels

map (key: string, value: string)

The labels for the session.

  • Label keys must be between 1 and 63 characters long and must conform to the following regular expression: [a-z]([-a-z0-9]*[a-z0-9])?.
  • Label values must be between 0 and 63 characters long and must conform to the regular expression ([a-z]([-a-z0-9]*[a-z0-9])?)?.
  • No more than 64 labels can be associated with a given session.

See https://goo.gl/xmQnxf for more information on and examples of labels.

createTime

string (Timestamp format)

Output only. The timestamp when the session is created.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

approximateLastUseTime

string (Timestamp format)

Output only. The approximate timestamp when the session is last used. It is typically earlier than the actual last use time.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

creatorRole

string

The database role which created this session.

multiplexed

boolean

Optional. If true, specifies a multiplexed session. Use a multiplexed session for multiple, concurrent read-only operations. Don't use them for read-write transactions, partitioned reads, or partitioned queries. Use sessions.adapter to create multiplexed sessions. Don't use sessions.batchCreate to create a multiplexed session. You can't delete or list multiplexed sessions.
