    • adaptMutations

      protected Collection<com.google.bigtable.v2.Mutation> adaptMutations(Mutation mutation)

      Description copied from class: MutationAdapter
      Converts an HBase Mutation which represents a set of changes to a single row from an HBase perspective to a collection of Cloud Bigtable Mutation which represent the set of changes. The name "Mutation" represents a more granular change in Bigtable than an HBase "Mutation"; An HBase Cell is akin to a Cloud Bigtable Mutation. A CloudBigtable MutateRowRequest or MutateRowsRequest.Entry is akin to an HBase Mutation.

      Specified by:

      adaptMutations in class MutationAdapter<Mutation>

      Parameters:

      mutation - The HBase Mutation to convert

      Returns:

      a Collection of Cloud Bigtable Mutation
