Writes multiple KV entries using the executor batch contract. Valid items share commit facts where the underlying engine applies them together.

Itemwise batches return one positional item result per input item. The outer batch status summarizes whether all, some, or none of the items succeeded.

Examples

Write many entries in one commit.

CLI

$ strata command run --command-json '{"entries":[{"key":"YQ==","value":"MQ=="},{"key":"Yg==","value":"Mg=="}],"type":"kv_batch_put"}'
$ strata command run --command-json '{"keys":["YQ==","Yg=="],"type":"kv_batch_get"}'

Wire

{"entries":[{"key":"YQ==","value":"MQ=="},{"key":"Yg==","value":"Mg=="}],"type":"kv_batch_put"}
{"keys":["YQ==","Yg=="],"type":"kv_batch_get"}

Parameters

Name	Type	Required	Description
entries	BatchKvEntry[]	yes	Entries to write.

Plus the optional scope: branch and space (default to the session branch and the "default" space).

Returns

BatchResult<KvMutationItem>.
