Example 1 with CheckAndSetCompatibility

use of com.palantir.atlasdb.keyvalue.api.CheckAndSetCompatibility in project atlasdb by palantir.

the class TransactionManagers method getTransactionSchemaInstallerIfSupported.

private static Optional<TransactionSchemaInstaller> getTransactionSchemaInstallerIfSupported(@Output List<AutoCloseable> closeables, KeyValueService keyValueService, Supplier<AtlasDbRuntimeConfig> runtimeConfigSupplier, TransactionSchemaManager transactionSchemaManager) {
    CheckAndSetCompatibility compatibility = keyValueService.getCheckAndSetCompatibility();
    if (compatibility.supportsCheckAndSetOperations() && compatibility.supportsDetailOnFailure()) {
        return Optional.of(initializeTransactionSchemaInstaller(closeables, runtimeConfigSupplier, transactionSchemaManager));
    }
    runtimeConfigSupplier.get().internalSchema().targetTransactionsSchemaVersion().filter(version -> version != TransactionConstants.DIRECT_ENCODING_TRANSACTIONS_SCHEMA_VERSION).ifPresent(version -> log.warn("This service seems like it has been configured to use transaction schema version {}," + " which isn't supported as your KVS doesn't support details on CAS failures" + " (typically Postgres or Oracle).

    return Optional.empty();
}
