The primary change introduced in this commit is partitioning of
the `TaggedCache`, with each partition being indepedent of each
other, making it possible to potentially perform multiple cache
operations in parallel. In particular, the `sweep` operation is
now parallelized by default on systems with at least four cores
present.
The `TaggedCache` could also be instantiated in 'key-only' mode
which complicated the interface significantly but was only used
by a single consumer (the `FullBelowCache`). This commit splits
the 'key-only' functionality of `TaggedCache`, and incorporates
directly into `FullBelowCache`, resulting in simple and cleaner
interfaces for both `TaggedCache` and `FullBelowCache` but at a
cost: some code duplication.
Lastly, this commit includes a medley of changes, including the
restructuring of `Transaction`, reducing its size by 48 bytes.
* Add a new operating mode to rippled called reporting mode
* Add ETL mechanism for a reporting node to extract data from a p2p node
* Add new gRPC methods to faciliate ETL
* Use Postgres in place of SQLite in reporting mode
* Add Cassandra as a nodestore option
* Update logic of RPC handlers when running in reporting mode
* Add ability to forward RPCs to a p2p node
When processing the `tx` command, we will now load both the transaction
and its metadata directly from SQLite.
Previously the `tx` RPC call was querying SQLite for the transaction
and then separately querying the key-value store for the metadata.
* The `tx` command now supports min_ledger and max_ledger fields.
* If the requested transaction isn't found and these fields are
provided, the error response indicates whether or not every
ledger in the the provided range was searched.
This fixes#2924
At this point all of the jss::* names are defined in the same
file. That file has been named JsonFields.h. That file name
has little to do with either JsonStaticStrings (which is what
jss is short for) or with jss. The file is renamed to jss.h
so the file name better reflects what the file contains.
All includes of that file are fixed. A few include order
issues are tidied up along the way.
Add a LedgerMaster function to get a ledger's
close time from either its hash or sequence number.
Use this function when adding the 'date' fields to
transaction JSON. This avoids constructing large numbers
of ledgers.
* Move InboundTransactions to app/ledger
* Move TransactionAcquire to app/ledger
* Move LocalTxs to app/ledger
* Move Transaction to app/misc
* Move TransactionMaster to app/ledger
