  1. def addSplits[K](tableName: String, accumuloInstance: AccumuloInstance, keyBounds: KeyBounds[K], keyIndexer: KeyIndex[K], count: Int): Unit

    Split the given Accumulo table into the given number of tablets.

    Split the given Accumulo table into the given number of tablets. This should improve the ingest performance, as it will allow more than one tablet server to participate in the ingestion.

    tableName

    The name of the table to be split

    accumuloInstance

    The Accumulo instance associated with the ingest

    keyBounds

    The KeyBounds of the RDD that is being stored in the table

    keyIndexer

    The indexing scheme used to turn keys K into Accumulo keys

    count

    The number of tablets to split the table into

  2. def getSplits[K](kb: KeyBounds[K], ki: KeyIndex[K], count: Int): Seq[BigInt]

    Mapping KeyBounds of Extent to SFC ranges will often result in a set of non-contigrious ranges.

    Mapping KeyBounds of Extent to SFC ranges will often result in a set of non-contigrious ranges. The indices exluded by these ranges should not be included in split calculation as they will never be seen.
