requestTag property
A per-request tag which can be applied to queries or reads, used for statistics collection.
Both request_tag
and transaction_tag
can be specified for a read or
query that belongs to a transaction. This field is ignored for requests
where it's not applicable (for example, CommitRequest
). Legal characters
for request_tag
values are all printable characters (ASCII 32 - 126) and
the length of a request_tag is limited to 50 characters. Values that
exceed this limit are truncated. Any leading underscore (_) characters are
removed from the string.
Implementation
core.String? requestTag;
