sendrawtransaction
The transaction will be sent unconditionally to all peers, so using sendrawtransaction for manual rebroadcast may degrade privacy by leaking the transaction's origin, as nodes will normally not rebroadcast non-wallet transactions already in their mempool.
A specific exception, RPC_TRANSACTION_ALREADY_IN_CHAIN, may throw if the transaction cannot be added to the mempool.

Argument #3-maxburnamount
Type: numeric or string, Optional
Default="0.00"
Description: Reject transactions with provably unspendable outputs (e.g. 'datacarrier' outputs that use the OP_RETURN opcode) greater than the specified value, expressed in BTC. If burning funds through unspendable outputs is desired, increase this value. This check is based on heuristics and does not guarantee spendability of outputs.
