bd batch

Run multiple write operations in a single database transaction.

Commands are read from stdin (one per line) or from a file via -f/--file. All operations execute inside a single dolt transaction: on any error the whole batch is rolled back, otherwise it is committed with one DOLT_COMMIT.

This is intended for shell scripts that currently invoke 'bd' many times in a loop, which causes severe write amplification on a dolt sql-server backed by btrfs+compression. Batching collapses N invocations into one transaction and one dolt commit.

Grammar (one command per line): close <id> [reason...] update <id> <key>=<value> [<key>=<value> ...] create <type> <priority> <title...> dep add <from-id> <to-id> [type] dep remove <from-id> <to-id> #comment (blank lines and '# ...' comments are ignored)

Supported 'update' keys: status, priority, title, assignee Supported dependency types: see 'bd dep add --help' (default: blocks)

Tokens are whitespace-separated. Double-quoted strings ("like this") may contain spaces; use " to embed a quote and \ for a backslash.

Examples:

From a pipe

bd list --status stale -q | awk '{print "close",$1," stale"}' | bd batch

From a file

bd batch -f operations.txt

Inline

printf 'close bd-1 done\nupdate bd-2 status=in_progress\n' | bd batch

On success, exits 0 and prints a summary (or JSON with --json). On any error, rolls back the entire transaction and exits non-zero with the failing line.

NOTE: This is a narrow subset. Commands like 'show', 'list', 'ready', 'sync', complex create flows, or any flag not listed above are NOT accepted. Use normal 'bd' subcommands for interactive/read operations.
