+ * Vectorized (batch) updater for nanosecond-precision timestamps: reads an
INT64 epoch-nanos
+ * column and decomposes each value into the two-child column vector
(epochMicros: Long,
+ * nanosWithinMicro: Short). Sub-microsecond digits are truncated to the
requested precision.
+ * Mirrors the row-based `newConverter` path which calls
+ * `DateTimeUtils.epochNanosToTimestampNanos(value, precision)`.
+ *
+ * No datetime rebase is applied (TIMESTAMP(NANOS) postdates the proleptic
Gregorian switch).
+ * No timezone conversion is applied at the storage level.
+ *
+ * Replaces the former `ParquetVectorUpdaterFactory.TimestampNanosUpdater`,
now owned by the
Review Comment:
Nit: stale reference to `TimestampNanosUpdater`.
