      .dingodb.pb.common.RequestInfo request_info = 1;
      Returns:
      The requestInfo.

    • getRequestInfoOrBuilder

      Common.RequestInfoOrBuilder getRequestInfoOrBuilder()
      .dingodb.pb.common.RequestInfo request_info = 1;

    • hasContext

      boolean hasContext()

      Returns:
      Whether the context field is set.

    • getContext

      Store.Context getContext()
      .dingodb.pb.store.Context context = 2;
      Returns:
      The context.

    • getContextOrBuilder

      Store.ContextOrBuilder getContextOrBuilder()
      .dingodb.pb.store.Context context = 2;

    • getMutationsList

      List<Store.Mutation> getMutationsList()
       In this case every `Op` of the mutations must be `PessimisticLock`.
      repeated .dingodb.pb.store.Mutation mutations = 3;

    • getMutations

      Store.Mutation getMutations(int index)
       In this case every `Op` of the mutations must be `PessimisticLock`.
      repeated .dingodb.pb.store.Mutation mutations = 3;

    • getMutationsCount

      int getMutationsCount()
       In this case every `Op` of the mutations must be `PessimisticLock`.
      repeated .dingodb.pb.store.Mutation mutations = 3;

    • getMutationsOrBuilderList

      List<? extends Store.MutationOrBuilder> getMutationsOrBuilderList()
       In this case every `Op` of the mutations must be `PessimisticLock`.
      repeated .dingodb.pb.store.Mutation mutations = 3;

    • getMutationsOrBuilder

      Store.MutationOrBuilder getMutationsOrBuilder(int index)
       In this case every `Op` of the mutations must be `PessimisticLock`.
      repeated .dingodb.pb.store.Mutation mutations = 3;

    • getPrimaryLock

      com.google.protobuf.ByteString getPrimaryLock()
      bytes primary_lock = 4;
      Returns:
      The primaryLock.

    • getStartTs

      long getStartTs()
      uint64 start_ts = 5;
      Returns:
      The startTs.

    • getLockTtl

      long getLockTtl()
       the lock's ttl is timestamp in milisecond, it's the absolute timestamp when the lock is expired.
      uint64 lock_ttl = 6;
      Returns:
      The lockTtl.

    • getForUpdateTs

      long getForUpdateTs()
       Each locking command in a pessimistic transaction has its own timestamp oracle.
 If locking fails, then the corresponding SQL statement can be retried with a later timestamp oracle, Executor does
 not need to retry the whole transaction. The name comes from the `SELECT ... FOR UPDATE` SQL statement which is a
 locking read. Each `SELECT ... FOR UPDATE` in a transaction will be assigned its own timestamp oracle.
      uint64 for_update_ts = 7;
      Returns:
      The forUpdateTs.

    • getReturnValues

      boolean getReturnValues()
       If it is true, store will return values of the keys if no error, so executor can cache the values for
 later read in the same transaction.
      bool return_values = 8;
      Returns:
      The returnValues.
