TON Index (C++ Worker)

This is a C++ worker for TON indexer. This worker reads data from TON node files, parses TL-B schemas, and inserts data into PostgreSQL database.

1. How to install

Before installing the worker, ensure the TON Index database is set up using the instructions provided.

1.1. Setup as systemd daemon

To install as a daemon use the script below:

./scripts/add2systemd.sh --db /var/ton-work/db --host <ip> --port <port> \
                         --user <postgres user> --password <postgres password> --dbname <database name> \
                         --from 1 --max-active-tasks $(nproc) --threads $(nproc) \
                         --max-insert-actors <number of insert actors> [--force]

You may find the list of arguments in section available arguments. Use flag --force to force rebuild binary.

NOTE: We strongly recommend to setup worker separately from the database server because of significant RAM and Disk IO usage.

1.2. Manual install

Do the following steps to build and run index worker from source.

  1. Install required packages:

     sudo apt-get update -y
 sudo apt-get install -y build-essential cmake clang openssl libssl-dev zlib1g-dev gperf wget git curl libreadline-dev ccache libmicrohttpd-dev pkg-config libsecp256k1-dev libsodium-dev python3-dev libpq-dev ninja-build

  2. Build TON index worker binary:

     mkdir -p build
 cd build
 cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=off -GNinja ..
 ninja -j$(nproc) ton-index-postgres

  3. Install binary to your system:

     sudo cmake --install

  4. Increase maximum opened files limit:

     ulimit -n 1000000

  5. Run TON index worker:

     ton-index-postgres <args>

1.3. Available arguments:

  • --db <path> - path to TON node directory. Pass /var/ton-work/db, if you have TON node installed by mytonctrl. Required.
  • --host <ip> - PostgreSQL host. Only IPv4 is acceptable. Default: 127.0.0.1.
  • --port <port> - PostgreSQL port. Default: 5432.
  • --user <user> - PostgreSQL user. Default: postgres.
  • --password <password> - PostgreSQL password. Default: empty password.
  • --dbname <dbname> - PostgreSQL database name. Default: ton_index.
  • --from <seqno> - Masterchain seqno to start indexing from. Use value 1 to index the whole blockchain.
  • --max-active-tasks <count> - maximum parallel disk reading tasks. Recommended value is number of CPU cores.
  • --max-queue-blocks <size> - maximum blocks in queue (prefetched blocks from disk).
  • --max-queue-txs <size> - maximum transactions in queue.
  • --max-queue-msgs <size> - maximum messages in queue.
  • --max-insert-actors <actors> - maximum concurrent INSERT queries.
  • --max-batch-blocks <size> - maximum blocks in batch (size of insert batch).
  • --max-batch-txs <size> - maximum transactions in batch.
  • --max-batch-msgs <size> - maximum messages in batch.
  • --threads <threads> - number of CPU threads.
  • --stats-freq <seconds> - frequency of printing a statistics.
