Examples with StartTransactionRequestV4 com.palantir.lock.v2.StartTransactionRequestV4 used on opensource projects

Example 1 with StartTransactionRequestV4

use of com.palantir.lock.v2.StartTransactionRequestV4 in project atlasdb by palantir.

the class AsyncTimelockResource method startTransactions.

/**
 * Returns a {@link StartTransactionResponseV4} which has a single immutable ts, and a range of timestamps to
 * be used as start timestamps.
 *
 * It is guaranteed to have at least one usable timestamp matching the partition criteria in the returned timestamp
 * range, but there is no other guarantee given. (It can be less than number of requested timestamps)
